1. Disconnect the solar array and
measure the battery voltage whether is
too high; 2. Change the controller; 3.
Change the battery

The controller cut off the output
automatically. LED indicator will return to
green automatically when fully
The radix point of
digital tube fast
flashing and load not
working
Short circuit
Clear short circuit. It is reactivated after
delayed 10 seconds for the first time, If
over 1 time，press the key to clear error
and the controller will resume to work
after 3s or restart the controller

digital tube slowly
flashing and load not
working
Over load
Please reduce the number of electric
equipments.
When load power reaches 1.25-1.5
times, 1.5-2 times and 2 times more than
nominal value, controller will
automatically close loads in 60 seconds,
5 seconds and 1 second, respectively.
Please press the key to clear error and
