3.2 Basic Settings
When the system is put into service for the first time, the parameters of controller module must be set based on the
actual system configuration, such as battery number, capacity, user’s charge current limit and other functional
requirements. Only after that can the controller module display system operation information and control the output.
(M221S,M222S controller password is 2; M225S controller password is1 )
The system model has been set correctly in factory before delivery, check that the setting agrees with the
