COMM 71-500900-XXG 1 Same with VM-2000
Note: “XX” in the sheet of PCBA number is the version of semi-finished PCBA.
4.1 Main board
The main board consists of SPS, DC-DC converter, inverter, charger, MCU control. Many semiconductors
and easy-failure components on the board, so it should be pay more attention when the system is
abnormal.
4.2 SCC board
The solar current control (SCC) board based on a MPPT control mode for VM-2000 and VM-1000 .When
the solar source is presented, battery charged from solar source; MAX charge current is 40A@ VM-2000
and VM-1000, if solar panel with enough energy.
4.3 COMM board
This inverter/charger is equipped with a communication port to communicate with a PC with corre
sponding software. Please use supplied communication cable to connect to communication port of
this inverter and USB port of the PC.
