★When the internal temperature is 81℃, the reducing power charging mode which
reduce the charging power of 5%,10%,20%,40% every increase 1 ℃is turned on. If
the internal temperature is greater than 85℃, the controller will stop charging. But
while the temperature decline to be below 75 º C, the controller will resume.

4.3 Maintenance

The following inspections and maintenance tasks are recommended at least two
times per year for best performance.

Make sure controller firmly installed in a clean and dry ambient.

Make sure no block on air-flow around the controller. Clear up any dirt and
fragments on radiator.

Confirm that PV and battery
wire connections are correct
and tight
Please check the voltage of
battery. At least 8V voltage to
activate the controller.
Check if battery voltage is
higher than OVD(over voltage
disconnect voltage), and
disconnect the PV.
When the battery voltage is
restored to or above LVR(low
voltage reconnect voltage), the
load will recover
The controller will
automatically turn the system
off. But while the temperature
decline to be below 55 º C, the
controller will resume.
①Please reduce the number
of electric equipments.
②Restart the controller.
③wait for one night-day cycle
(night time>3 hours).
①Check carefully loads
connection, clear the fault.
②Restart the controller.
