Measure and judge if the voltage of
battery is too high, and switch off the
wiring of solar array.
When operating ambient temperature or
battery temperature reaches more than
85°C, controller will automatically cut off
input and output circuit.
When the temperature is less than 75°C,
controller will automatically recover the
connection of input and output circuit.
Please restart controller, if the fault still
exists, immediately cut off charging and
discharging circuit and contact the
supplier to make maintenance.
Please reduce the number of electric
equipments. When load power reaches
1.05-1.25 times, 1.25-1.5 times and 1.5
times more than nominal value, controller
will automatically close loads in 60
seconds, 5 seconds and 1 second,
respectively. It is reactivated after delayed
5 seconds for the first time, 10 seconds for
the second time, 15 seconds for the third
