DIP Switches

Turning SW5 on the DIP switch to position 1, the machine will be solar priority model.
At this model, the load can be fed by the batteries or mains alternately under specific transition
condition.
By turning the Battery Type Selector you can change the transition condition in order to match
different battery types. All transition conditions are listed below and the numbers stand for the
directing of the arrow in the Battery Type Selector.
From mains feeding to battery feeding
NO.1 to NO.8. If the solar is on, the mains charging current should be less than 2A AC, and
the solar charging current should be less than 10A DC. If the solar is off, the solar charging
current should be less than 10A DC. After achieving these conditions, the machine will transform
in 10 minutes.
NO.9. If the solar is on, the solar charging current should be less than 10A DC. After
achieving this condition, the machine will transform in 10 minutes. If the solar is off, the machine
can't transform.
From battery feeding to mains feeding
NO.1 to NO.6. If the single battery voltage is less than 11V DC, the machine will transform
immediately.
NO.7. If the single battery voltage is less than 11.6V DC, the machine will transform
immediately.
NO.8. If the single battery voltage is less than 12V DC, the machine will transform
immediately.
NO.9. If the single battery voltage is less than 12.4V DC, the machine will transform
immediately.
