Pure Sine Wave
The Renogy Power Inverters output a pure sine wave similar to the waveform of the grid power. In a pure sine wave, the voltage rises and falls in a smooth fashion with very low harmonic distortion and cleaner utility-like power.
This gives users stable enough power to operate tools, fans, lights, computers, and other electronics without any interference. Pure sine wave inverters are in many cases more efficient, allowing users to use less energy and allow for more device capability. The main advantage to pure sine wave inverters is that they are used to operate sensitive electronic devices that require a high quality waveform with little harmonic distortion. Almost any electronic device could be powered using a pure sine wave inverter.

Included Components
Battery Temperature Sensor (BTS)
Renogy inverter chargers come equipped with a battery temperature sensor that will help prolong the battery life. The temperature sensor allows the charge controller to continuously adjust the charging voltage based on the battery temperature. The charging voltage will be reduced by 0.1V for every degree of temperature above 104
℉. The battery temperature sensor should be installed on all battery banks as it ensures that the battery receives the proper voltage. The sensor mounts on the side of the battery.

Additional Components
Additional component can be purchased for extra functionality.
LCD Remote Control Module (RCM)
The inverter-chargers feature a remote LCD port for connecting this additional switch panel. It will have the same functionality as the main panel located on the invertercharger such as “off”, “power saver off”, or “power saver on”. Additionally, the LCD RCM displays input and output AC/DC voltage, output frequency, alarm notifications, and battery status.
When connecting the LCD RCM, it will connect in parallel to the inverter charger’s main switch board. This means to turn the inverter on, both the LCD RCM and the inverter charger switch board need to be in the off position first. Whichever board switches first, will power the inverter charger.
6
If commands from the two boards conflict with each other, the following priorities will automatically take place:
Power Saver On > Power Saver Off > Power Off
Both panels in the off position will power the inverter off.
NOTE: When the inverter is in Battery-priority mode, finishes a complete charging cycle, and switches to inverter
mode, “AC: Abnormal” will be displayed.
NOTE: In AC mode, the LCD will not display the status of the AC load

Location Recommendations
WARNING: Never install the inverter in a sealed enclosure with flooded batteries.
Gas can accumulate and there is a risk of explosion.
Ensure installation follows the following guidelines:
1. Cool, dry, well-ventilated area
—Heat is the worst enemy for electronic equipment. Inverters must be in an area where the fans are not blocked or where they are not hit directly by the sun. They should be in an area free of any kind of moisture and allow for clearance of at least 10” around the unit to provide for adequate ventilation.
2. Protection against fire hazard
—the unit should be away from any flammable material, liquids, or any other combustible material. The unit can spark and the consequences could be severe.
3. Close proximity to battery bank
—prevent excessive voltage drop by keeping the unit close to the battery bank and having a properly sized wire going from the battery bank to the inverter.
4. WARNING : Do not install the inverter in the same compartment as the battery bank because it could serve as a potential fire hazard.
5. Limiting electromagnetic interference (EMI)
—ensure the inverter is firmly grounded to a building, vehicle, or earth grounded. Keep the inverter away from
EMI receptors such as TVs, radios, and other audio/visual electronics to prevent damage/interference to the equipment.
6. Secure inverter
—the inverter could be stand alone or mounted using the outlying terminals on the inverter.
WARNING: The inverter should never be mounted vertically on a vertical surface since it would present a hazard for the fan opening which is crucial for cooling the inverter.
Sizing a Battery Bank
1. Determine the amount of Watts (Amps * Volts) for the load, and how long the load needs to operate
—each electrical appliance has a technical specifications indicating the watts, or the volts and amps required for operation.
2. Estimate load run-time
—determining a battery size relies heavily on load watts and run-times. Most loads will not be constant, so estimations are key.
3. Utilize the formula Watts = Volts * Amps
4. Determine Amps used for how many hours
– Amp-hour (Ah)
11
*For this Renogy Inverter Charger, the battery bank will be 12 volts direct current
(12 VDC)
Example
A Microwave = 700 Watts
12V battery bank
700 Watts to run microwave using the batteries as if it was a 12VDC microwave requires 58 Amps
700 Watts / 12 Volts = 58 Amps
Load Operation = 3 hours
Now that amps have been determined, the amps hours need to be determined. The microwave will be used for approximately 3 hours a day.
58 Amps * 3 hours = 174 Ah
At least a 174 Ah battery must be selected in order to use the 700 Watt microwave at
3 hours a day. However, determining a battery size is also dependent on the battery that is able to handle repeated discharge/charge cycles.
NOTE: This is just an example. Actual quantities vary by battery capacity and rates of discharge.
NOTE: In the example above, the user would need to be using at least the Renogy
1000W Pure Sine Wave Inverter Charger.
Grounding
The Renogy Pure Sine Wave Inverter Chargers come equipped with a grounding lug for appropriate grounding to earth ground or to another designated ground (For example, a metal frame of an RV). The connections to ground must be tight and against bare metal.
Whether using the inverter in a mobile application, such as an RV or in a building, grounding is highly recommended. The recommended wire size for grounding is 8 AWG copper wire. For more information regarding grounding, users and/or installers must consult with the Local and National Electric Codes (NEC) for more specific grounding regulations and suggestions as they can change per scenario.
12
DC Wiring
CAUTION: We recommend installing the inverter as close as possible to the battery bank. The torque rating for the DC terminal is 12.5NM-20.5NM. The torque rating suggested is 17NM.

AC Wiring
WARNING: AC Output should NEVER be connected to public power or a generator.
CAUTION: When connecting to an AC source we recommend using 6-10AWG wire
and wiring just like the picture below. (120V Single Phase Wiring Only). Consult a
qualified electrician about specific wire gauge in terms of material and inverter
power.
AC Input: Ground-Hot Line-Neutral
AC Output: Neutral-Hot Line-Ground
Automatic Neutral-to-Ground Connection
CAUTION: Be careful of the positive and negative poles. Reversing the poles might cause permanent damage to the inverter. It will surely blow the internal fuse.
NOTE: Damage to the Renogy inverters due to reverse polarity is NOT covered by warranty.
13
NOTE: The input terminals of the inverters have large capacitors connected to them. Once a positive and negative wire are connected to the terminals, it will complete the circuit, and commence drawing a heavy current momentarily. As a result, there may be a sparking occurring even if the inverter is in the off position.
To minimize sparking, it is recommended that the user have the appropriate size wire feeding into the inverters and/or install an external fuse leading into the
inverter.
The Renogy Inverter Charger is equipped with an automatic neutral-to-ground switch.
The inverter uses an internal relay to connect the AC neutral output to the vehicles/boats ground in inverter mode and disconnects it when an external AC source is detected.
Operation
AC Charger
The Renogy inverter comes equipped with a 4-stage battery charger and an 8-battery type selector switch. The charging current can be adjusted from 25%-100%. The charging current will vary depending on the inverter model.

Bulk Stage: The charger will supply constant current until the battery voltage reaches the boost voltage. The software will calculate the time charging began up until the battery voltage reaches 0.3V below the boost voltage. It uses this time to as T0 and
T0×10 = T1.
Boost Stage: The charger will supply constant voltage and reduce the current slowly through this stage. The charger will stay in this stage until T1 has run out. After this time the charger will enter the float stage. This stage will last between 1 hour and 12 hours depending on T1.
Float Stage: During this stage the charger will supply a constant voltage which is determined by the battery selected and will keep current at a minimum. This stage acts as a trickle charger.
Equalization: This stage is only available if the battery selector is switched to position
8. During this stage the batteries are charged at a higher voltage than normal and for
15
most batteries this could cause damage. Please refer t o the batteries owner’s manual or contact the manufacturer to see if this stage is needed.
Transfer Switch
The inverters come with a 20A/30A transfer switch that allows the inverters to switch between AC shore power and AC inverter mode (DC to AC) in a matter of 10 milliseconds. The inverter will automatically switch to battery power when the AC input voltage drops below 90VAC.

SW 1 (Low Battery Disconnect):
This switch can change the low battery disconnect between 10.0V-11.5V. Depending on whether shore power is present or not the low voltage set point will change. For most applications, the voltage should be set to 11.5V to prevent the batteries from being depleted.
SW 2 (AC Input Range):
Most electronics have a recommended AC voltage range and staying within this range will allow the electronic to function normally. Some electronics will function between
100-130VAC 60Hz while other accept a lower frequency 40-60HZ. If the AC source falls below 50Hz or 100VAC then position 1 will need to be used.
SW 3 (Power Saver):
The inverter’s power saver mode is activated when position 1 is selected. The inverter will detect a load for 250ms every 3 seconds and if a load is detected the inverter will start outputting AC power.
NOTE:
If the switch position is set to 0 and power saver mode is selected on the inverter main power switch, then no AC power will be outputted unless there is shore power connected to the inverter.
SW 4 (Frequency Switch):
16
The inverter can be set to output 50Hz or 60Hz using this switch
SW 5 (Battery/AC Priority):
When the inverter is set to battery priority (Position 1) it will invert power from the battery bank to the AC outlets until the low voltage set point is reached. If there is an AC source connected while under battery priority it will charge the battery after the low voltage is reached and use the AC source to power the AC outlets. When the battery is fully charged, the inverter will switch to battery power.
When choosing AC priority (Position 0) the battery power will only be used when there is no shore power connected to the inverter. Once AC power is connected the inverter will start charging the battery bank. If shore power is present for 15 continuous days, then the inverter will use the battery bank for one cycle. This cycle is used to prolong battery life.

Troubleshoot
Use a multi-meter to check the voltage of the battery. Make sure the battery voltage is not below the rated specification of the inverter. The inverters have an input requirement of at least 10.5 ± 0.5 volts. Disconnect battery if necessary.
Use a multi-meter to check the voltage of the battery. Make sure the battery voltage is not exceeding the rated specification of the inverter. The maximum input voltage should not be exceeding 16 volts.
Turn off the inverter and check the rated specification for the electronic device(s). Be sure to check that the watts
(volts * amps) does not exceed the specification for the inverter. Be very cautious if using power strips as they can be clear indicator for overload for inverters.
Also, some electronic devices may require an initial high power surge start. Make sure all AC appliances are off before turning on the inverter’s power switch.
Short Circuit
A short might occur down the DC line connecting to the inverter. Check the battery connections going to the inverter and ensure that there is continuity. If there is an inline fuse installed, check to make sure the fuse has not
Other Considerations
blown. Reset the inverter by turning it off for approximately
5 seconds and powering it back on.
Battery cables are connected to the inverter but it does not power on
The inverter needs a minimum of 10.5 volts to operate. Use a multi-meter to make sure the battery levels are suitable for operation. If all checks out, check the wire connections and inspect for any breaks or tears.
Make sure the inverter is switched to Power saver on or
Power saver off.
The AC input voltage is not within the acceptable range.
Idle draw from inverter
When the inverter is switched on, the circuitry inside is activated. Even if there is no load on the AC side of the inverter, users will experience a small amount of current draw to keep the circuitry within the inverter ready to power.
It is recommended to turn off the inverter when not in use.
The inverter is only able to run AC loads for a short period of time
This will happen when the battery voltage is low. Check battery voltage and resume running loads when battery voltage is above 12.7 volts.
20
External Fusing
Fusing is a recommended in PV systems to provide a safety measure for connections going from panel to controller and controller to battery. Remember to always use the recommended wire gauge size based on the PV system and the controller.
