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.
Gen_Start_relay (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).
Gen_ON_relay (9,10): reserved.
RSD_short signal: reserved.
RSD_voltage signal: reserved.
RSD 12V_out 15+16-: reserved.
ATS: 230V output port when inverter is on.
Note: Normally only 1pcs CT is needed only,
and the secondary side of the CT should
be connected to 5&6 port (CT-L2).
