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.

1-1-2. To avoid a risk of fire and electronic shock. Make sure that existing wiring is in good electrical condition; and that wire size is not undersized. Do not operate the Inverter with damaged or substandard wiring.

1-1-3. This equipment contains components which can produce arcs or sparks. To prevent fire or explosion do not install in compartments containing batteries or flammable materials or in locations 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 userserviceable parts. Attempting to service the Inverter/Charger yourself may result in a risk of 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 RV Series

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, PLEASE NOTE THAT THE APC SERIES 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 for at least 20 minutes and get medical attention immediately.

1-2-2. Never smoke or allow a spark or flame in vicinity of battery or engine.

1-2-3. Do not drop a metal tool on the battery. The resulting spark or short-circuit on the battery of other electrical part 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

APC Series Pure Sine Wave Inverter is a combination of an inverter, battery charger and AC auto-transfer 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 APC 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 battery in renewable energy systems.

Thus, the APC Series Pure Sine Wave Inverter is suitable for Renewable energy system,Utility, RV, Marin 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 APC inverter/charger is built according to the following topology.

Invert: Full Bridge Topology.

Charge: Isolate Boost Topology

The peak efficiency of APC series is 88%.

Overload Capacity

The APC series inverters have different overload capacities, making it ideal to handle demanding loads.

1 For 110%<Load<125%(±10%), no audible alarm in 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 the 1 minute.

3 For 300%≧Load>150%(±10%), beeps 0.5s every 1s and Fault(Turn off) after 20s.

2.5.2 AC Charger

APC Series is equipped with an active multistage battery charger.

The APC series inverter is with a strong charging current of 90Amp(for 3KW,12V), and the max charge current can be adjusted from 0%-100% via a liner switch at the right of the battery type selector. The liner switch can effectively reduce the max charging current to 20% of its peak.

Choosing “0” in the battery type selector will disable charging function.

There are mainly 3 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.

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 fl oat charge voltage (determined by the Battery Type

7

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 reset the cycle above.

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 on switch position 8 is marked in red because this is a very dangerous setting if you do not know what you are doing. Before ever 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 left 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 taking a charge and thus allow the plates to clean up and so accept charge once again.

Charging depleted batteries

The APC series inverter allows start up and through power with depleted batteries.

NOTE:

① The optional battery temperature sensor automatically adjusts the charging process of the controller according to the type of the battery is selected by user through battery type selector. With the battery temperature sensor installed, the controller will increase or decrease the battery charging voltage depending on the temperature of the battery to optimize the charge to the battery and maintain optional performance of

the battery.

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 all the power they are capable of.

The PV-seeker Charge controller is a microprocessor-based system designed to implement the MPPT.

And it can increase charge current up to 30% or more compared to traditional charge controllers (see figure

1).

Figure 1 Current, Power vs. Voltage Characteristics

2.5.4 Power Saver

There are 2 different working status for APC inverter: “Power On” and “Power Off”.

When power switch is in “Unit Off” position, the inverter is powered off.

When power switch is in either of “Power Saver

Auto” or “Power Saver Off”, the inverter is powered on.

Power saver function is to dedicated to conserve battery power when AC power is not or little 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.

10

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 DIP switch.

Note: The minimum power of load to take inverter out of sleep mode (Power Saver On) is 25 Watts.

2.5.5 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), 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.

There is a 15-second delay from DC to AC.

2.5.6 Automatic Voltage Regulation*

The automatic voltage regulation function is only for APS Pure Sine Wave Inverter/ Charger which is a combination of APC inverter and Automatic Voltage Regulator.

Instead of simply bypassing the input AC to power the loads, the APS series inverter stabilizes the input AC voltage to a range of 230V/120V±10%.

Connected with batteries, the APS inverter will function as a UPS with max transfer time of 10 ms.

With all the unique features from the inverter and AVR, it brings you long-term trouble free operation beyond your expectation.

2.5.7 Protections

The APC 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.

12

The Low batter voltage trip point can be customized from defaulted value 10VDC to 10.5VDC thru the SW1 on DIP switch.

Output) after 30 seconds. The switch has to be reset to activate the inverter.

The APC series Inverter is with back feeding protection which avoids presenting an AC voltage on the AC input terminal in Invert mode.

After the reason for fault is cleared, the inverter has to be reset to start working.

2.5.8 Remote control

Apart from the switch panel on the front 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.

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 accept command according to the following priority:

Power saver on> Power saver off> Power off

Only when both panels are turned to “Unit Off” position, the inverter will be powered off.

2.5.11 FAN Operation

For 1-3KW, there is one multiple controlled DC fan which starts to work according to the following logics.

For 4-6KW, there is one multiple controlled DC fan and one AC fan. The DC fan will work in the same way as the one on 1-3KW, 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.
