4. Installation
Proper installation is crucial for the safe and efficient operation of your solar inverter. It is recommended that installation be performed by a certified electrician or qualified professional.
4.1 Mounting the Inverter
- Choose a dry, cool, and well-ventilated area, away from flammable materials.
- Mount the inverter vertically on a sturdy wall or surface.
- Ensure sufficient clearance around the inverter for proper airflow and heat dissipation.
4.2 Wiring Connections
Follow the wiring diagram carefully. All connections must be tight and secure to prevent loose connections, which can cause overheating or damage.
- PV Input: Connect solar panels to the PV input terminals. Ensure the total PV open circuit voltage (VOC) does not exceed 500VDC and the starting voltage is greater than 60V. Recommended PV wire size: 12AWG.
- Battery Connection: Connect the 24V battery bank to the battery terminals. Recommended battery cable size: 2AWG. Ensure correct polarity.
- AC Input: Connect the utility grid or generator to the AC input terminals. Recommended AC wire size: 12AWG.
- AC Output: Connect your loads to the AC output terminals.
- Grounding: Connect the inverter to an earth ground using a protective conductor.

5. Operation
Once installed, the inverter can be configured and operated via its LCD display and control buttons.
5.1 Initial Startup
- Ensure all wiring connections are correct and secure.
- Connect the battery bank to the inverter.
- Connect the solar panels to the PV input.
- Connect the AC input (utility or generator) if applicable.
- Turn on the inverter's power switch. The LCD display will illuminate, showing system status.
5.2 Charging and Output Modes
The inverter offers flexible modes to suit various energy requirements:
- Battery Charging Modes:
- Solar First: Prioritizes solar energy for battery charging. Utility/generator charges only when solar is insufficient.
- Solar and Utility: Solar and utility/generator charge the battery simultaneously.
- Only Solar: Only solar energy charges the battery, regardless of utility availability.
- Load Output Working Modes:
- Utility First: Prioritizes utility power for loads. Inverter switches to battery/solar only when utility is unavailable.
- Solar First: Prioritizes solar power for loads. Switches to utility/battery when solar is insufficient.
- SBU Priority (Solar-Battery-Utility): Prioritizes solar, then battery, then utility for powering loads.
