First connect the battery, then the load, and finally the solar panel. When
wiring, follow the order of first "+" and then "-".
④ Power on
After connecting all power wires solidly and reliably, check again whether
wiring is correct and if the positive and negative poles are reversely
connected. After confirming that no faults exist, first close the fuse or
breaker of the battery, then see whether the LED indicators light up and the
LCD screen displays information. If the LCD screen fails to display
information, open the fuse or breaker immediately and recheck if all
connections are correctly done.
If the battery functions normally, connect the solar panel. If sunlight is
intense enough, the controller's charging indicator will light up or flash and
begin to charge the battery.
After successfully connecting the battery and photovoltaic array, finally
close the fuse or breaker of the load, and then you can manually test
whether the load can be normally turned on and off. For details, refer to
information about load working modes and operations.
Warning: when the controller is in a normal charging state,
disconnecting the battery will have some negative effect on the DC loads,
and in extreme cases, the loads may get damaged.
Warning: within 10 minutes after the controller stops charging, if the
battery's poles are reversely connected, internal components of the
controller may get damaged.
Note:
1) The battery's fuse or breaker shall be installed as close to the battery side as possible, and
it's recommended that installation distance be not more than 150mm.
2) If no remote temperature sensor is connected to the controller, the battery temperature value
will stay at 25 °C.
3) If an inverter is deployed in the system, directly connect the inverter to the battery, and do not
connect it to the controller's load terminals.
