System diagram applied to electric meters:
Notice!
D series& M series + X1 MATEBOX BASIC supports parallel
function. M series + X1 MATEBOX ADVANCED does not
support parallel function.
Notice!
The BMS port on the inverter is the communication port for
connecting the battery. The communication port on the lithium
battery must be consistent with the definition of pins 4, 5, 7, and
8 above.
The series inverters provide parallel function, and up to 2 inverters can be
connected in a system. In this system, one inverter is set as the "master
inverter", and the other inverter is switched to the "slave inverter" state,
and the inverters are connected to communicate through the CAN line.
The converter "controls the "slave inverter".
Notice!
At present, there are only PIN6 (DRM0) and PIN1 (DRM1 /5), and
other PIN functions are under development.
