Warning: Risk of explosion. Short circuit of battery positive and negative terminals
and wires connected to them will cause fire or explosion. Please be careful during operation.
Please connect battery first, then connect load, and finally connect the solar panel,
please follow the connection mode of "+" first and then "-".

Power On
Tip: ML series solar charge controller only starts the solar charge controller via wiring at
the battery end, but ML - LI can start the solar charge controller via power of PV array,. This
applies to starting the solar charge controller and activating lithium battery when lithium
battery BMS is in the protection state and cannot export electricity externally.
When all the power line connections are firm and reliable, recheck whether the wiring is
correct, and whether positive and negative ends are connected reversely. After confirmation,
connect battery fuse or circuit breaker, observe whether LED indicator is lit, and whether LCD
screen displays content. If there is no display, disconnect the fuse or circuit breaker
immediately and recheck whether the circuit connection is correct.
If battery is powered on normally, connect the solar panel. If solar charge controller
charging indicators are on normally or flashing, start battery charging.
When battery and photovoltaic is well connected, then connect load fuse or circuit
breaker. At this time, you can use manual mode to test whether the load On and Off is normal.
See load working mode and operation.
Warning: When the solar charge controller is under normal charging state,
disconnecting battery connection will affect solar charge controller DC load. In a severe case,
the load can be damaged.
Warning: Within 10 minutes after solar charge controller charging stops, battery
reverse polarity operation may damage internal components of the solar charge controller.
Attention:
1
）
Battery insurance installation site should be as close as possible to the battery end.
Recommended installation distance shall be no more than 150 mm.
2
）
When solar charge controller is not connected to a remote temperature sensor,
battery temperature is a fixed value of 25 ℃.
3
）
If the inverter is connected in the system, please connect inverter directly with
battery, and do not connect solar charge controller with the load end.

Close wiring cover
When all wirings of the system are well connected, close the wiring cover
and screw screws tight.
