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 split phase system.
CT-L2 (5,6): current transformer (CT2) for
“zero export to CT”mode clamps
on L2 when in split phase system.
G-start (7,8): 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 (9,10): reserved.
RSD (11,12): provide 12Vdc output when
inverter is on.
ATS: 230V output port when inverter is on
Note: For - EU model (7.6/8kW,230V@50Hz),
1pcs CT is needed only, and the secondary
side of the CT should be connected to
5&6 port (CT-L2).

RS 485: RS 485 port for battery
communication.
CAN: CAN port for battery
communication.
Parallel A: Parallel communication port 1
(CAN interface).
Parallel B: Parallel communication port 2
(CAN interface).
*Meter_CON: for energy meter communication.
*Some hardware versions don't
have this port.
