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 inverter charger 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 inverter-
charger 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.

7
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 bykeeping 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)

12
*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.

13
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.

14
NOTE: Damage to the Renogy inverters due to reverse polarity is NOT covered by
warranty.
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.

Battery Charging Stages
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.

16
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
most batteries this could cause damage. Please refer to 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.

17
SW 4 (Frequency Switch):
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.

The Renogy Inverter Charger has two working mode: “Power Saver Off” and “Power
Saver AUTO”
When the inverter is switched on to Power Saver Off the inverter will supply AC power
without any interruptions.

18
When the inverter is switched on to Power Saver AUTO the inverter will send a signal to
the AC loads for 250ms every 3 seconds and if an AC device (50W+) is connected the
inverter will start supplying power. NOTE: To activate this mode DIP switch 3 must be set
to position 1.
The idle consumption when using power saver mode is approximately 8 watts.

Troubleshoot
Under Voltage Alarm
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.
Over Voltage Alarm
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.
Over Load Protection
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 in-
line fuse installed, check to make sure the fuse has not
blown. Reset the inverter by turning it off for approximately
5 seconds and powering it back on.
Other Considerations
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.
There is no AC output
or LED indicator
lights on
Make sure the inverter is switched to Power saver on or
Power saver off.
The battery charger
turns off while
connected to an
external AC source
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.
