• N and PE wiring via ON-GRID and BACK-UP ports of the inverter are different based on the
regulation requirements of different regions. Refer to the specific requirements of local
regulations.
• There are built-in relays inside of the inverter's ON-GRID and BACK-UP AC ports. When the
inverter is in the off-grid mode, the built-in ON-GRID relay is open; while when the inverter
is in grid-tied mode, it is closed.
• When the inverter is powered on, the BACK-UP AC port is charged. Power off the inverter
first if maintenance is required for the loads connected with BACK-UP ports. Otherwise, it
may cause electric shock.
• Only GEH series inverters support PV
N and PE cables are connected together in the Main Panel for wiring.
