1. Connect the battery.
2. Start the inverter.
3. Connect the circuit breakers for PV, grid, and load.

To power off, follow the reverse order.

5. Operating Instructions

5.1 Charging Modes

The inverter offers three charging modes to meet diverse user application requirements:

• Solar Energy Priority: Solar power is prioritized for charging the battery and powering loads.
• Solar + Utility Simultaneously: Both solar and grid power are used concurrently for charging and powering loads.
• Solar Only Battery Charging: Only solar energy is used to charge the battery.

5.2 Output Modes

The inverter provides two output modes to cover the electrical needs of a wide range of equipment:

• Solar Priority Output, then Utility: Solar power is prioritized for loads, then supplemented by utility power.
• Solar Output Priority, then Battery, then Grid: Solar power is prioritized, then battery power, and finally grid power for loads.
