Type 3: Special grid topology
Please follow the below circuit diagram to configure the connection:
For the following grid topology, the standard hybrid inverter is NOT applicable.
Please contact Solis to purchase necessary accessories to be compatible with them.
Requirements:
1. A special contactor box (Automatic change-over switch box)
2. Special firmware update
NOTE:
With the change-over switch installed and the firmware updated, the hybrid
inverter’s backup port WILL NOT supply power unless the grid fails.
When the grid fails, the contactor switches inside the box will switch on the
backup port and the loads will be supported by the backup port only
(Power from battery and PV).
