3 / 3
Pin 6(US2000C/US3000C).
For direct-pin communication inverter, please make sure the communication cable Pin1/2/3
are NULL. Or alternatively order the correct communication cable (WI0SCAN30RJ1) or
external cable kits (BW0US3000BAL0007) from us.
For cross-pin communication inverter, please make sure it`s strictly follow the Pin order and
requirements defined above to make the cable. It needs to highlight that due to Pin1/2/3
shall be NULL, some of the premade cross-pin communication cable supplied by inverter
manufacture will be not applicable.
Apart from above two points, for some inverter operation interface it also supports manual
settings of the operation voltage on the battery module. Under lithium battery operation
mode such kind of manual settings might be followed in case the communication with
battery is lost. Please make sure the charge cut-off voltage is set at 53.2 – 52.5Vdc,
discharge cut-off voltage is set at 45.5Vdc or higher for US2000C/US3000C.
