1. Important Safety Information
WARNING! Before using the Inverter, you need to read and save the safety instructions.
1-1. General Safety Precautions
1-1-1.Do not expose the Inverter to rain, snow, spray, bilge or dust. To reduce risk of hazard, do not cover or obstruct the ventilation openings. Do not install the Inverter in a zero-clearance compartment. Overheating may result. Allow at least 30CM of clearance around the inverter for air flow. Make sure that the air can circulate freely around the unit. A minimum air flow of 145CFM is required.
1-1-2. To avoid risk of fire and electronic shock, make sure that existing wiring is in good electrical condition and that the wire is not undersized. Do not operate the Inverter with damaged or substandard wiring.
1-1-3. This equipment contains components which may produce arcs and/or sparks. To prevent fire and/or explosion do not install in compartments containing batteries or flammable materials or in a location which require ignition protected equipment. This includes any space containing gasoline-powered machinery, fuel tanks, or joints, fittings, or other connection between components of the fuel system.
See Warranty for instructions on obtaining service.
1-1-4. Do not disassemble the Inverter/Charger. It contains no user-serviceable parts. Attempting to service the Inverter/Charger yourself may result in electrical shock or fire. Internal capacitors remain charged after all power is disconnected.
1-1-5. To reduce the risk of electrical shock, disconnect both AC and DC power from the Inverter/Charger before attempting any maintenance or cleaning. Turning off controls will not reduce this risk
CAUTION: Equipment damage
The output side of the inverter’s AC wiring should at no time be connected to public power or a generator.
This condition is far worse than a short circuit. If the unit survives this condition, it will shut down until corrections are made.
Installation should ensure that the inverter’s AC output is, at no time, connected to its AC input.
Warning: Limitations On Use
SPECIFICALLY NOTE THAT THE GLOBAL LF INVERTER/CHARGER SHOULD NOT BE USED IN
CONNECTION WITH LIFE SUPPORT SYSTEMS OR OTHER MEDICAL EQUIPMENT OR DEVICES.
1-2. Precautions When Working with Batteries
1-2-1. If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters eye, immediately flood eye with running cold water and get medical attention immediately.
1-2-2. Never smoke or allow a spark or flame in the vicinity of a battery or engine.
1-2-3. Do not drop a metal tool on the battery. The resulting spark or short-circuit on the battery may cause an explosion.
1-2-4. Remove personal metal items such as rings, bracelets, necklaces, and watches when working with a lead-acid battery. A lead-acid battery produces a short-circuit current high enough to weld a ring or the like to metal, causing a severe burn.
1-2-5. To reduce the risk of injury, charge only deep-cycle lead acid, lead antimony, lead calcium gel cell, absorbed mat, or NiCad/NiFe type rechargeable batteries. Other types of batteries may burst, causing personal injury and damage.

2. Introduction
2-1. General Information
Global LF Series Pure Sine Wave Inverter is a combination of an inverter, battery charger and AC autotransfer switch into one complete system with a peak conversion efficiency of 88%.
It is packed with unique features and it is one of the most advanced inverter/chargers in the market today.
It features power factor corrected, sophisticated multi-stage charging and pure sine wave output with unprecedentedly high surge capability to meet demanding power needs of inductive loads without endangering the equipment.
For the regular model, when utility AC power cuts off(or falls out of acceptable range), the transfer relay is de-energized and the load is automatically transferred to the Inverter output. Once the qualified AC utility is restored, the relay is energized and the load is automatically reconnected to AC utility.
The Global LF Series Inverter is equipped with a powerful charger of up to 90Amp(depending on model).
The overload capacity is 300% of continuous output for up to 20 seconds to reliably support tools and equipment longer.
Another important feature is that the inverter can be easily customized to Battery priority via a DIP switch, this helps to extract maximum power from the battery in renewable energy systems.
Thus, the Global LF Series Pure Sine Wave Inverter is suitable for Renewable energy systems, Utility, RV,
Marine and Emergency appliances.
To get the most out of the power inverter, it must be installed, used and maintained properly. Please read the instructions in this manual before installing and operating.

2.5 Electrical Performance
2.5.1 Invert
Topology
The Global LF inverter/charger is built according to the following topology.
Invert: Full Bridge Topology.
Charge: Isolate Boost Topology
Because of high efficiency Mosfets and 16bit, 4.9MHZ microprocessor and heavy transformers, it outputs
PURE SINE WAVE AC with an average THD of 15% (min 5%, max 25%) depending on the load connected and the battery voltage.
The peak efficiency of the Global LF series is 88%.
Overload Capacity
The Global LF series inverters have high overload capacities, making it ideal to handle demanding loads.
1 For 110%<Load<125%(±10%), no audible alarm for 14 minutes, beeps 0.5s every 1s in the 15th minute, and Fault(Turn off) after the 15th minute.
2 For 125%<Load<150%(±10%), beeps 0.5s every 1s and Fault(Turn off) after 1 minute.
Caution:
After the inverter is switched on, it takes a finite time for it to self diagnose and get ready to deliver full power. Hence, always switch on the load(s) after a few seconds of switching on the inverter. Avoid switching on the inverter with the load already switched on. This may prematurely trigger the overload protection.
When a load is switched on, it may require initial higher power surge to start. Hence, if multiple loads are being powered, they should be switched on one by one so that the inverter is not overloaded by the higher starting surge if all the loads are switched on at once.

AIMS Power www.aimscorp.net
2.5.2 AC Charger
Global LF Series is equipped with an active PFC (Power Factor Corrected) multistage battery charger. The
PFC feature is used to control the amount of power used to charge the batteries in order to obtain a power factor as close as possible to 1.
Unlike other inverters whose max charging current decreases according to the input AC voltage, Global LF series charger is able to output max current as long as the input AC voltage is in the range of 164-
243VAC(95-127VAC for 120V model), and AC freq is in the range of 48-54Hz(58-64Hz for 60Hz model).
The Global LF series inverter has a very rapid charge current available, and the max charge current can be adjusted from 0%-100% via a liner switch at the right of the battery type selector. This will be helpful if you are using our powerful charger on a small capacity battery bank. Fortunately, the liner switch can effectively reduce the max charging current to 20% of its peak.
Choosing “0” in the battery type selector will disable the charging function.
Caution:
Pls turn the charge current control switch gently to avoid breakage due to over-turning.
There are 3 charging stages:
Bulk Charging: This is the initial stage of charging. While Bulk Charging, the charger supplies the battery with controlled constant current. The charger will remain in Bulk charge until the Absorption charge voltage
(determined by the Battery Type selection) is achieved.
A software timer will measure the time from A/C start until the battery charger reaches 0.3V below the boost voltage, then take this time asT0 and T0×10 = T1.
Absorb Charging: This is the second charging stage and begins after the absorb voltage has been reached.
Absorb Charging provides the batteries with a constant voltage and reduces the DC charging current in order to maintain the absorb voltage setting.
In this period, the inverter will start a T1 timer; the charger will keep the boost voltage in Boost CV mode until the T1 timer has run out. Then drop the voltage down to the float voltage. The timer has a minimum time of 1 hour and a maximum time of 12 hours.
Float Charging: The third charging stage occurs at the end of the Absorb Charging time. While Float charging, the charge voltage is reduced to the float charge voltage (determined by the Battery Type selection*). In this stage, the batteries are kept fully charged and ready if needed by the inverter.
If the A/C is reconnected or the battery voltage drops below 12Vdc/24Vdc, the charger will restart the above cycle.
If the charge maintains the float state for 10 days, the charger will deliberately reset the cycle to protect the battery.

De-sulphation
The de-sulphation cycle, switch position 8, is marked in red because this is a very dangerous setting if you do not know what you are doing. Before attempting to use this cycle you must clearly understand what it does and when and how you would use it.
What causes sulphation? This can occur with infrequent use of the batteries, or if the batteries have been discharged so low that they will not accept a charge. This cycle is a very high voltage charge cycle designed to try to break down the sulphated crust that is preventing the plates from taking a charge and thus allow the plates to clean up and accept a charge once again.
Charging depleted batteries
The Global LF series inverter allows start up and through power with depleted batteries.
For 12VDC models: after the battery voltage goes below 10V and the power switch is kept in the "ON"
10
AIMS Power www.aimscorp.net
position and the inverter stays connected to the battery and the battery voltage doesn’t drop below 2V, the inverter will be able to charge the battery once qualified AC inputs are present.
Before the battery voltage goes below 9VDC, the charging can be activated when the switch is turned to
“Off”, then to “ON”.
When the voltage goes below 9VDC, and you accidently turn the switch to OFF or disconnect the inverter from the battery, the inverter will not be able to charge the battery once again, because the CPU loses memory during this process.

The charging capacity will go to peak charge rate in about 3 seconds. This may cause a generator to drop frequency, making the inverter transfer to battery mode.
It is suggested to gradually put the charging load on the generator by switching the charging switch from min to max. Together with the 15s switch delay our inverter gives the generator enough time to spin up.
This will depend on the size of the generator and rate of charge.
2.5.3 Transfer
While in the Standby Mode, the AC input is continually monitored. Whenever AC power falls below the
VAC Trip voltage (154 VAC, default setting for 230VAC,90VAC for 120VAC), the inverter automatically transfers back to the Invert Mode with minimum interruption to your appliances - as long as the inverter is turned on. The transfer from Standby mode to Inverter mode occurs in approximately 10 milliseconds. And it is the same time from Inverter mode to Standby mode.
Though it is not designed as a computer UPS system, this transfer time is usually fast enough to keep your equipment powered up.
There is a 15-second delay from the time the inverter senses that continuously qualified AC is present at the
11
AIMS Power www.aimscorp.net
input terminals to when the transfer is made. This delay is built in to provide time for a generator to spin-up to a stable voltage and avoid relay chattering. The inverter will not transfer to generator until it has locked onto the generator’s output. This delay is also designed to avoid frequent switching when input utility is unstable.
2.5.4 Auto Frequency Adjust
The inverter is designed with an Auto Frequency adjust function.
The factory default configuration for inverters sold in American market is 60Hz.
If the output frequency needs to be changed this is done by putting in a valid input Power Source to the inverter’s input lines. Once the inverter validates the input, the output will automatically change.
NOTE: The inverter will output factory set frequency of 60Hz after it restarts. Customers who can only accept 50Hz frequency at startup, should notify AIMS Power when ordering.

Maximum Power Point Tracking (MPPT) Function
Maximum Power Point Tracking, frequently referred to as MPPT, is an electronic system that operates the
Photovoltaic (PV) modules in a manner that allows the modules to produce the maximum power they are capable of.
The PV-seeker Charge controller is a microprocessor-based system designed to implement the MPPT.
It can increase the charge current up to 30% or more compared to traditional charge controllers (see figure
1).
Figure 1 Current, Power vs. Voltage Characteristics
The Charge controller built in was designed with 12/24V battery voltage auto detecting function.
For 12VDC inverter, the output voltage of the solar charger will be accordingly 12VDC, and the qualified
DC input volt range is 15v-30VDC.
For 24VDC inverters, the output voltage of the solar charger will be accordingly 24VDC, and the qualified
DC input volt range is 30v-55VDC.
If the voltage falls out of this range, the charger will not work properly. Special attention should be paid to this when configuring the solar array.
2.5.6 Automatic Voltage Regulation
The automatic voltage regulation function is for the full series of Global LF Pure Sine Wave Inverter/
Chargers with the exception of split phase models, including PICGLF50W24V230VS,
PICGLF50W48V230VS, PICGLF60W24V230VS, and PICGLF60W48V230VS.
Instead of simply bypassing the input AC to power the loads, the Global LF series inverter stabilizes the input AC voltage to a range of 230V/120V±10%.
Connected with batteries, the Global LF inverter will function as a UPS with max transfer time of 10 ms.
With all the unique features and top quality minded design our inverter provides, it will provide you with
13

2.5.7 Power Saver
There are 2 different working statuses for our
Global LF inverter: “Power On” and “Power Off”.
14
AIMS Power www.aimscorp.net
When the power switch is in “Unit Off” position, the inverter is powered off.
When the power switch is turned to either of “Power Saver Auto” or “Power Saver Off”, the inverter is powered on.
Power saver function is designed to conserve battery power when AC power is not or rarely required by the loads.
In this mode, the inverter pulses the AC output looking for an AC load (i.e., electrical appliance). Whenever an AC load (greater than 25 watts) is turned on, the inverter recognizes the need for power and automatically starts inverting and output goes to full voltage. When there is no load (or less than 25 watts) detected, the inverter automatically goes back into search mode to minimize energy consumption from the battery bank.
In “Power saver on” mode, the inverter will draw power mainly in sensing moments, thus the idle consumption is significantly reduced.
The inverter is factory defaulted to detect a load for 250ms every 30 seconds. This cycle can be customized to 3 seconds thru SW3 on the DIP switch.
Power saver on Power saver off Power saver on(Load detected)
Note: The minimum power of load to take inverter out of sleep mode (Power Saver On) is 25 Watts.
The Global LF Series is designed with extraordinarily low idle power consumption which is only a mere
0.8-1.8% of its rated power.

When in the search sense mode, the green power LED will blink and the inverter will make a ticking sound.
At full output voltage, the green power LED will light steadily and the inverter will make a steady humming sound. When the inverter is used as an “uninterruptible” power supply the search sense mode or “Power
Saver On” function should be defeated.
Exceptions
Some devices when scanned by the load sensor cannot be detected. Small fluorescent lights are the most common example. (Try altering the plug polarity by turning the plug over.) Some computers and sophisticated electronics have power supplies that do not present a load until line voltage is available. When this occurs, each unit waits for the other to begin. To drive these loads either a small companion load must be used to bring the inverter out of its search mode, or the inverter may be programmed to remain at full output voltage (Power On mode).
2.5.8 Protections
The Global LF series inverter is equipped with extensive protections against various harsh situations/faults.
These protections include:
AC Input over voltage protection/AC Input low voltage protection
Low battery alarm/High battery alarm
Over temperature protection/Over load protection
Short Circuit protection (1s after fault)
Back feeding protection
When Over temperature /Over load occur, after the fault is cleared, the master switch has to be reset to restart the inverter.
The Low battery voltage trip point can be customized from a defaulted value of 10VDC to 10.5VDC thru
SW1 on the DIP switch.
(shutdown Output) after 30 seconds. The switch has to be reset to activate the inverter.
16
AIMS Power www.aimscorp.net
The Global LF series Inverter has back feeding protection which avoids presenting an AC voltage on the AC input terminal in Invert mode.
After the reason for the fault is cleared, the inverter has to be reset to start working.
2.5.9 Remote Control
Apart from the switch panel on the front (or top) of the inverter, an extra switch panel connected to the RJ11 port at the DC side of the inverter thru a standard telephone cable can also control the operation of the inverter (sold separately Part # PICGLFREMOTE).
If an extra switch panel is connected to the inverter via “remote control port”, together with the panel on the inverter case, the two panels will be connected and operated in parallel.
Whichever first switches from “Off” to “Power saver off” or “Power saver on”, it will power the inverter on.
If the commands from the two panels conflict, the inverter will operate according to the following priority:
Power saver on> Power saver off> Power off
Only when both panels are turned to the “Unit Off” position, will the inverter be powered off.
The Max length of the cable is 10 meters.
WARNING
Never cut the telephone cable when the cable is attached to inverter and battery is connected to the inverter.
Even if the inverter is turned off. It will damage the remote PCB inside if the cable is short circuited during cutting.

2.5.12 FAN Operation
For 1-3KW models, there is one multiple controlled DC fan which starts to work according to the below logic.
19
AIMS Power www.aimscorp.net
For 4-6KW models, there is one multiple controlled DC fan and one AC fan. The DC fan will work in the same way as the 1-3KW models, while the AC fan will work once there is AC output from the inverter.
So when the inverter is in power saver mode, the AC fan will work from time to time in response to the pulse sent by the inverter in power saver mode.
The Operation of the DC fan at the DC terminal side is controlled by the following logic:

Low Battery Trip Volt:
Deep discharge of the lead acid battery leads to high losses in capacity and early aging. In different applications a different low voltage disconnection level is preferred. For example, for solar applications, user may intend to have less DOD to prolong the battery life cycle. While for mobile applications users may intend to have more DOD to reduce battery capacity and on board weight.
For 12VDC models, the Low Battery Trip Volt is set at 10.0VDC by default. It can be customized to
10.5VDC using SW1. This is to prevent batteries from over-discharging while there is only a small load applied on the inverter.
*2 for 24VDC, *4 for 48VDC
AC Input Range:
There are different acceptable AC input ranges for different kinds of loads.
For some relatively sensitive electronic devices, a narrow input range of 184-253VAC (100-135V for
120VAC model) is required to protect them.
While for some resistive loads which work in a wide voltage range, the input AC range can be customized to
20
AIMS Power www.aimscorp.net
154-264VAC (90-135V for 120VAC model), this helps to power loads with the most AC input power without frequent switches to the battery bank.
In order to make the inverter accept dirty power from a generator, when the SW2 is switched to position “1”, the inverter will bypass an AC input with a wider voltage and frequency (40Hz plus for 50Hz/60Hz).
Accordingly, the AC charger will also work in a wider freq range (43Hz plus for 50Hz/60Hz).
This will avoid frequent switches between battery and generator. But some sensitive loads will suffer from the low quality power.
The pros and cons should be clearly realized.
Load Sensing Cycle:
The inverter is factory defaulted to detect load for 250ms in every 30 seconds. This cycle can be customized to 3 seconds thru the SW3 on the DIP switch.
AC/Battery Priority:
Our inverter is designed with AC priority by default. This means, when AC input is present, the battery will be charged first, and the inverter will transfer the input AC to power the load. Only when the AC input is stable for a continuous period of 15 days will the inverter start a battery inverting cycle to protect the battery. After 1 normal charging cycle ac through put will be restored.
The AC Priority and Battery Priority switch is SW4. When you choose battery priority, the inverter will invert from battery despite the AC input. Only when the battery voltage reaches the low voltage alarm point(10.5V for 12V) will the inverter transfer to AC Input, charge battery, and switch back to battery when the battery is fully charged. This function is mainly for wind/solar systems using utility power as back up.
Note: In battery priority mode, when qualified AC inputs for the first time, the inverter will only go into battery priority mode after a cycle of bulk charging and absorb charging is finished. The inverter will not go into float charging mode.
2.5.14 Output Socket
The inverter is either equipped with a dual GFCI socket (rated at 30Amps) or an universal socket (rated at
10Amps) for more convenient wiring.
2.5.15 Other Features
Battery voltage recovery start
After low battery voltage shut off (10V for 12V model or 20V for 24V model), the inverter is able to restore operation after the battery voltage recovers to 13V/26V (with power switch still in the “On” position). This function helps to save the users extra labor to reactivate the inverter when the low battery voltage returns to an acceptable range in the renewable energy systems. The built in battery charger will automatically reactivate as soon as city/generator ac has been stable for 15 seconds.
WARNING
Never leave the loads unattended, some loads (like a Heater) may cause accident in such cases.
21
AIMS Power www.aimscorp.net
It is better to shut everything down after low voltage trip than to leave your load on, due to the risk of fire.
Auto Gen Start
The inverter can be customized to start up a generator when the battery voltage goes low.
When the inverter goes to low battery alarm, it can send a signal to start a generator, and turn the generator off after battery charging is finished.
The auto gen start feature will only work with generators designed to work with this feature. There is an open/close relay that will short circuit the positive and negative cable from a generator. The input DC voltage can vary, but the Max current the relay can carry is 16Amp.
Conformal Coating
AIMS Power entire line of Global LF inverters have been processed with a conformal coating on the PCB, making it water, rust, and dust resistant as well as corrosion resistant.
While these units are designed to withstand corrosion from the salty air, they are not splash proof.

Symptom
Inverter will not turn on during initial power up.
No AC output voltage and no indicator lights ON.
AC output voltage is low and the inverter turns loads OFF in a short time.
Charger is inoperative and unit will not accept AC.
Charger is supplying a lower charge rate.
Possible Cause
Batteries are not connected, loose battery-side connections.
Recommended Solution
Check the batteries and cable connections. Check DC fuse and breaker.
Low battery voltage.
Inverter has been manually transitioned to OFF mode.
Low battery.
AC voltage has dropped out-of-tolerance
Charger controls are improperly set.
Charge the battery.
Press the switch to Power saver on or Power saver off position.
Check the condition of the batteries and recharge if possible.
Check the AC voltage for proper voltage and frequency.
Refer to the section on adjusting the “Charger Rate”.
Low AC input voltage.
Source qualified AC power..
27
AIMS Power www.aimscorp.net
Charger turns OFF while charging from a generator.
Sensitive loads turn off temporarily when transferring between grid and inverting.
Noise from Transformer/case*
Loose battery or AC input connections.
High AC input voltages from the generator.
Inverter's Low voltage trip voltage may be too low to sustain certain loads.
Applying specific loads such as hair drier
Check all DC /AC connections.
Load the generator down with a heavy load.
Turn the generator output voltage down.
Choose narrow AC voltage in the
DIP switch, or Install a UPS if possible.
Remove the loads
*The reason for the noise from transformer and/or case
When in inverter mode sometimes the transformer and/or case of the inverter may vibrate and make noise.
If the noise comes from transformer:
According to the characteristics of our inverter, mainly there is one type of load which most likely may cause rattles of transformer.
That is half wave load: A load that uses only half cycle of the power. This tends to cause an imbalance of the magnetic field of the transformer, reducing its rated working freq from 20KHz to, say, maybe 15KHz (it varies according to different loads). In such a case the frequency of noise falls exactly into the range
(200Hz-20KHz) that human ears can hear.
The most common load of such kind is a hair drier.
If the noise comes from the case:
Normally when loaded with inductive loads, the magnetic field generated by the transformer keeps attracting or releasing the steel case at a specific freq, this may also cause noise.
Reducing the load power or using an inverter with bigger capacity will normally solve this problem.
The noise will not do any harm to the inverter or the loads.
5 Warranty
