Battery Charging Modes:
05
The solar inverter will have 4 operational charging modes which changes the logic as how and
when to charge the battery banks. The solar inverter has four working modes: PV priority, Utility
Priority, Hybrid Charging, and Only Solar Charging.
PV Priority
In PV Priority mode it will make full use of the solar input during the day in order to charge the
battery bank. This effectively allows using the unit off-grid during peak utility times in order to
cut costs on utility charging. Only when solar fails to start or is interrupted will the unit
automatically switch to utility mode for backup.
Photovoltaic Modules (PV): convert light energy into DC power, charge the battery through
the solar inverter charger, or directly reverse into alternating current to power the load.
PV
UTILITY
48V Battery Storage
Power or generator (Utility): Access at the AC input can power the load and charge the
battery. If you do not have a power supply or generator, the system can also operate normally,
where the load is supplied by batteries and photovoltaic modules.
Battery: The role of the battery is to ensure the normal use of electricity for the system load
when the solar energy is insufficient and there is no electricity.
Household load: Can be accessed to a variety of household and office loads, including
refrigerators, lamps, televisions, fans, air conditioning and other AC loads.
CHARGINGCHARGING

06
Utility Priority
In Utility Priority mode, the detected AC input will be priority for battery charging. If the power
becomes unstable or unusable, then it will switch to PV charging.
CHARGINGCHARGING
CHARGINGCHARGING
Hybrid Charging
In Hybrid Charging, PV and Utility will work together to charge the battery bank at the same
time. Priority will be given to PV and utilize MPPT charging. Upon PV charging being
insufficient, the power supply replenishes with Utility power. This method is the fastest to
charge and suitable for unstable areas of the grid, ready to provide adequate backup power
supply.
CHARGING
Only Solar Charging
Only solar charging is the most energy-efficient way to charge your battery bank and does not
make use of AC input. Utility will not charge the battery, even if it is available.

07
Load Output Working Modes
PV Priority
In this mode only the incoming solar energy and battery power are used to power the loads.
This can maximize the use of green energy when selecting PV priority in Battery Charging
Mode to achieve overall energy conservation and emission reduction. Upon there being no
more usable solar energy or the battery voltage drops to a low voltage setpoint, then the unit
will switch to utility power to continue to power up the loads. It is recommended to be in this
mode for relatively stable areas.
The solar inverter has 3 working modes that dictate how the incoming power is used to power
the loads.Users may configure the output source priority to configure load power.
CHARGING
CHARGING
CHARGING
Utility Priority
Equivalent to a backup UPS for use in unstable areas of the grid, Utility will provide power to
the loads as priority. Solar and battery energy will provide power to the loads only when utility
power is not available.
Inverter Mode
The Battery energy will supply power to the loads. Utility provides power to the loads only when
battery voltage drops to low voltage which maximizes the use of DC power.

exposed directly to the sun. They should be in an area free of any kind of moisture and
allow for clearance of at least 8” around the unit to provide adequate ventilation.
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.
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.
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.

WARNING
WARNING
The Renogy Solar Inverter is suitable for 48V battery banks systems ONLY. Not
following the minimum DC requirement may cause irreversible damage to the unit.
The solar inverter components at the AC input/output, battery components, and
PV components will produce high energy output. Make sure to connect the
appropriate component to the appropriate labeled terminals.
Be careful of the positive and negative poles. Reversing the poles may cause
permanent damage to the inverter.
After the power switch is switched off, there is still high energy inside the solar
inverter, do not open or touch the internal device, wait for the capacitance to be
put off after the relevant operation.
Locate the power button on the solar
inverter and make sure the solar inverter
main power is turned off
Remove the terminal cover by unscrewing
the appropriate terminals located on the
face of the solar inverter
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 solar inverters and/or install an external
fuse leading into the inverter.

The solar inverter takes a 48V battery input to operate. This will require combining 12V or 6V
batteries in series to achieve the minimum voltage DC requirement. It is recommended to use
battery cables with ring terminals. The ring terminals must be firmly tightened and secured on
the respective battery terminals to prevent any excessive heating or resistance. Connect the
positive and negative battery ring terminals to the respective positive and negative battery
terminals on the solar inverter.
When combining panels in parallel it is recommended to use a combiner box for safety and
organizational precautions. The solar inverter accepts a maximum of 150VDC input and
requires a 48V battery input to operate. This will require combining solar panels in series or
series parallel to achieve the minimum voltage DC requirement. Due to many factors affecting
PV performance, it is recommended to utilize the open circuit voltage (Voc) when connecting
panels in series to make sure you stay under the 150VDC input. For parallel connections, it is
recommended to use the short circuit current (Isc) to make sure you are well under the 80A limit.
The bare wire terminal blocks must be firmly tightened and secured to prevent any excessive
heating or resistance. Connect the positive and negative PV wire to the respective positive and
negative PV terminal block on the solar inverter.

Charging Parameters Glossary
Overvoltage Disconnect—
When and if the charge controller experiences a voltage
higher than what is assigned, it will disconnect itself from the circuit; ceasing charge.
Overvoltage Recover--
in the event a charge controller experiences an over-voltage
condition set by the previous parameter, then this reconnecting parameter is put into
play to direct the controller when it can connect and safely charge again. Typically
over-voltage reconnection is achieved when time has passed (ex. The sun setting), or
when the over-voltage condition is remedied ultimately reducing the voltage to a user
defined charging voltage.
Equalization Voltage--
equalization voltage is a corrective over-charge of the battery.
The user should consult their battery manufacturer regarding specific battery
equalization capacity. This parameter sets the equalization voltage to set the battery at
when it reaches the equalization state.
Boost Voltage--
users should check with their battery manufacturer for proper charging
parameters. In this stage, users set the boost voltage where the battery will reach a
voltage level and remain there until the battery undergoes an absorption stage.
Float Voltage--
once the charge controller recognizes the set float voltage, it will
commence floating. The battery is supposed to be fully charged in his state, and the
charge current is reduced to maintain battery stability levels.
Undervoltage Recover--
deals with the loads connected to the system. When batteries
are determined to be low due to them approaching low voltage disconnect, then the loads
will be shut off to give the batteries time to recover. This parameter sets the controller to
shut off the loads until it can reach the low voltage reconnect stage.
Undervoltage Alarm--
this parameter deals with the batteries themselves approaching
the under-voltage recovery state. The user should minimize loads before the charge
controller approaches a level where it will do this automatically to protect the battery from
discharging.
Low Voltage Recover--
parameter allows loads connected to the system will be able to
operate (not fully) again.
Low-voltage disconnect--
prevents over-discharge of the batteries by automatically
disconnecting any loads. This extends battery life and is the precedent to being in an
under-voltage state, recovering from the undervoltage state, and finally reconnecting to
normal operational state.

This equipment has been tested and found to comply with the limits for a class B digital device, pursuant to
part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses and can radiate radio frequency
energy and if not installed and used in accordance with the instructions, may cause harmful interference to
radio communications. However, there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct the interference
by one or more of the following measures:
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) this device may not cause harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired operation.
·
Reorient or relocate the receiving antenna.
·
Increase the separation between the equipment and receiver.
·
Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
·
Consult the dealer or an experienced radio/TV technician for help.
Discharging limit Voltage--
This parameter ensures that the controller does not exceed
the default or assigned parameter before needing to be charged again. This is put into
play to optimize and extend the battery life by going with a higher voltage. The lower the
discharge limit voltage the more negative effect on battery efficiency.
