CN1:
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.
CN2:
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).
G-valve (3,4): reserved.
Grid_Ry (5,6):
RSD (7,8): When battery is connected and the
inverter is in "ON" status, it will provide 12Vdc.
Parallel A: Parallel communication
port 1 (CAN interface).
Parallel B: Parallel communication
port 2 (CAN interface).
Meter_485: for energy meter
communication.
ModeBUS: Reserved.
BMS: BMS port for battery
communication(CAN/RS485).
