Connect the AC IN (grid) terminal to a stable grid power supply. If the grid voltage
fluctuates too frequently, or if the grid frequency is unstable, this may lead to phase
lock failure.
USB port is for data communication port only. There is no charging capacity.
When RS485 connect to PC port, needs and supporting the USB to RS485 converter,
cable with standard 8-core.
When the number of inverters in parallel,there must and only a master and one
slave to connect to the “CAN R”.
If would like to connect with PC program,please using the standard USB cable,softw
are and drive can be download from website(www.cnbou.com)

Under this option, the inverter output is the power supply. When the battery voltage is low, it
will switch to the grid supply or the power will shut off (if the grid is not connected). When the
inverter is providing power and the MPPT Controller is charging the batteries, the AC Charger
will stop charging. If you switch to Grid Priority, the AC Charger and the MPPT Controller can
charge the batteries together.
