Troubleshooting

Confirm that PV wire connections

are correct and tight

1) Please check the voltage of

battery. At least 9V voltage to

activate the controller

2) Check the PV input voltage

which should be higher than

battery's

Check if the battery voltage is

higher than OVD point (over

voltage disconnect voltage), and

disconnect the PV.

When the

battery

voltage

restored to or above LVR point

(low voltage reconnect voltage),

the load will recover

The controller will automatically

turn the system off. But while the

temperature decline to be below

50 ºC, the controller will resume.

Please reduce the number of

electric

equipments

check

carefully loads connection.
