①

When load current reaches1.02-1.05 times 1.05-1.25 times, 1.25-1.35 times and

1.35-1.5 times more than nominal value, controller will automatically turn off loads in 50s,

30s,10s and 2s respectively

4.3 Load mode setting

Operating Steps:

Under load mode setting interface, press SET button and hold on 5s till the number begin

flashing, then press MENU button to set the parameter, press SET button to confirm.

Troubleshooting

array

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 º C, the controller will resume.

Please reduce the number of

electric

equipments

carefully loads connection.
