General Information The new all-in-one Renogy Solar Inverter Charger is an advanced hybrid system combining the advanced charging algorithm of solar and industrial reliability and electrical energy of pure sine wave inverters to give you a complete power system. The unit features 4 charging modes and 3 output modes to meet an array of application needs.
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.
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.
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.

Installation Please read this manual carefully and familiarize yourself with the installation procedures before installation. WARNING CAUTION NOTE Indicates a potentially dangerous condition. Use extreme caution when performing this task. Indicates a critical procedure for safe and proper operation of the inverter. Indicates a procedure or function that is important to the safe and proper operation of the inverter.
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.
Wiring 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.
Wiring and installation methods must comply with national and local electrical specifications. The following chart is reference only. Longer wire runs between solar panels and the solar inverter as well as longer runs between the solar inverter and battery bank will require thicker wiring size to minimize loss and improve system performance.
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.
AC Output Wiring NOTE NOTE WARNING CAUTION Only the Live and Neutral wires will be connected to the Output Terminal Block, the Ground will be connected to the screw terminal. Make sure any circuit breakers are disconnected and ensure the unit is in the off position. AC Output should NEVER be connected to public power/utility or a generator. There are two terminal blocks with “IN” and “OUT” markings. Please do NOT misconnect input and output connectors.
AC Input Wiring WARNING NOTE CAUTION The AC input must never be connected to the AC output as irreversible overload or damage may result The AC Input Terminal Block is connected to circuit breakers for added protection. Do not modify or alter them as it may cause irreversible damage to the solar inverter. There are two terminal blocks with “IN” and “OUT” markings. Please do NOT mis-connect input and output connectors. Run the AC input line through the AC input cable entry slot.
Communication Ports Dry Contacts NOTE WARNING To use this to function, an auto start controller must be installed on the generator. there are three contacts; up to down: NO, N, NC Do not store units with auto gen start feature enabled. Generators exhaust dangerous fumes when running. This contact automatically starts the generator and charges the battery bank. Under normal conditions, this terminal is NC-N point closed, NO-N point open.
Operation ON Assuming all connections are correct and tightly secured, Locate the power button on the solar inverter and turn the main power switch to the ON position.

When modifying parameters in User Mode or Lithium, the following rules must be followed to set parameters successfully. 1. Overvoltage Disconnect > Overvoltage Disconnect Recover ≥ Equalization voltage ≥ Boost voltage ≥ Float voltage 2. Overvoltage Disconnect > Over Voltage Disconnect Recover 3. Low Voltage Disconnect Recover > Low Voltage Disconnect (at least 2V Smaller) < Discharge Limit Voltage 4.
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.
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. 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.
