PV
UTILITY
48V Battery Storage
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.
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.
Battery Charging Modes:
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.
CHARGING CHARGING
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.
CHARGING CHARGING
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 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.
CHARGING
06
Load Output Working Modes
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.
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.
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.
07
CHARGING
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.

Ensure installation follows the following guidelines:
1.
2.
3.
4.
5.
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 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.
WARNING
Do not install the inverter in the same compartment as the battery bank because it could serve as a potential fire hazard.
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.
10
Other Precautions:
When installing the battery, be very careful, when installing lead-acid liquid batteries, you should wear protective glasses, once in contact with battery acid, please wash with water in time.
Avoid placing metal objects near the battery to prevent short circuits in the battery.
Acid gas may be generated when the battery is charged so ensure good ventilation around the environment.
Incorrect or improper connection points and corroded wires can cause great heat to melt the wire insulation, burning surrounding materials, and even cause fire, so ensure that the connection is tightened it is best to avoid mobile applications when the wire shakes and cause the connection head loose.
Outdoor installation should avoid direct sunlight and rain, snow.
Do not install the solar inverter in harsh environments such as damp, greasy, flammable and explosive areas or where dust accumulation is high.
The municipal electrical input and AC output are high voltage, do not touch the wiring.
Do not touch the unit when the fan is working.
To avoid damage, do not use more than one (in parallel) input AC power supply.

WARNING
WARNING
CAUTION
NOTE
CAUTION
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.
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.
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.
ON
Locate the power button on the solar inverter and make sure the solar inverter main power is turned off
OFF
Remove the terminal cover by unscrewing the appropriate terminals located on the face of the solar inverter

Bare Wire
For PV to charge 48V battery banks, you will need a minimum PV Voc voltage of
60VDC.
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 50A 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.
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.
