CN1:
CT-R (1,2,7,8): current transformer (CT-R) for“zero
export to CT”mode clamps on L1 when
in three phase system.
CT-S (3,4,9,10): current transformer (CT-S) for“zero
export to CT”mode clamps on L2 when
in three phase system.
CT-T (5,6,11,12): current transformer (CT-T) 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 ac�ve, the open contact
(GS) will switch on (no voltage output).
DRY-1 (3,4): reserved
.
DRY-2 (5,6): reserved
.
RSD (7,8): When ba�ery is connected and the
inverter is in "ON" status, it will provide 12Vdc.
Meter: for energy meter communica�on.
Parallel_1: Parallel communica�on
port 1.
Parallel_2: Parallel communica�on
port 2 .
CAN: reserved
.
DRM: Logic interface for AS/
NZS 4777.2:2020.
BMS1: BMS port for ba�ery
communica�on port 1.
BMS2: BMS port for ba�ery
communica�on port 2.
