TEMP (1,2): battery temperature sensor for
lead acid battery.
CT-L1 (3,4): current transformer (CT1) for
“zero export to CT”mode clamps
on L1 when in three phase system.
CT-L2 (5,6): current transformer (CT2) for
“zero export to CT” mode clamps
on L2 when in three phase system.
CT-L3 (7,8): current transformer (CT3) for “zero export to CT” mode clamps on L3 when
in three phase system.
G-valve (3,4): Dry contact output. When the inverter is
in off-grid mode and the “Signal ISLAND MODE” is
checked, the dry contact will switch on.
Grid_Ry (5,6): reserved.
RSD (7,8): When the battery is connected and
the inverter is in “ON” status, it will provide
12Vdc.

G-Start (1,2): dry contact signal for startup the diesel generator. When the "GEN signal" is
active, the open contact (GS) will switch on (no voltage
output).
Parallel A: Parallel communication
port 1 (CAN interface).
Parallel B: Parallel communication
port 2 (CAN interface).
Meter_485: for energy meter
communication
Modbus: Reserved.
BMS: BMS port for battery
communication (CAN/RS485).
