Dry contact switch
NOTE!
When using generation remote start function , the generator must be
connected to the EV-SB's GEN terminals.
The dry 1 contact switch / dry 2 contact switch / dry 3 contact switch can
be used to implement Load Shed function.
Load Shed function can perform load management. It is intended to turn off
designated loads during low battery periods to conserve remaining battery
power.

The GEN dry contact switch is used as a controller for an AC generator with
a remote start function. The GEN dry contact switch may be used to start the
generator by closing the appropriate circuit.

Ÿ Connecting external CTs
CT placement locations include the following:
A set of CTs (CT L1A , CT L2A,200A) has been built in the EV-SB. In some
application scenarios ,it can measure both load and generation and there is
no need to connect external CTs.But in some application scenarios,such as
Partial-Home Backup solution,connecting external CTs (CT L1B , CT L2B) to
measure total current both load and generation is needed. In addition,if the
site includes solar equipment, a solar CT is placed after the solar inverter to
measure the solar output.
CT L1A terminal and CT L1B terminal have been connected in parallel on
PCB. CT L1A and CT L1B are used to measure total current both load and
generation of the same phase L1.
CT L2A terminal and CT L2B terminal have been connected in parallel on
PCB. CT L2A and CT L2B are used to measure total current both load and
generation of the same phase L2.
