Turn on and Turn off the controller
Automatic shutdown controller
When the controller is in the low voltage protection state (battery voltage < 11V) and is not in the charging state (at night or the
PV is not connected), the controller automatically shuts down after 1 minute. When charging is resumed, the controller reopens
automatically
Two-stage charging
Load overcurrent protection
1. 1.2 times overload :12A, Turn off the load in 60 seconds
2. 1.5 times overload :15A, Turn off the load in 20 seconds
1. Connect sequence: battery --solar array --loads
2. Wier size: min2.5mm
3. Grounding the solar system: Be aware that the positive terminals
of the SLDcontroller are connected internally and therefore have
the same electrical potential. if any grounding is required ,always
do this on the positive wires.

Connecting
Green ON: voltage normal
Green flash: battery full
Yellow: battery low
Green ON: charging
Green OFF: no PV or Evening
Green flash(1time/1s): PV overvoltage
Green flash(1time/2s): PV overpower
ON/OFF Switch
1. When the user only connects to the battery and does not connect the solar panel, the controller is turned off. If you need to turn
on the controller, you must press the button for 2 seconds.
2. When the user is connected to the battery and solar energy at the same time, the controller automatically starts charging, and
the load is ON
3. when the controller is working, after pressing the switch for 2 seconds, the controller is turned off, charging and discharge
stop. If you need the controller to work again, you must press the key again for 2 seconds, otherwise, In all cases, the controller
is off, including reconnect the battery and reconnect PV
When the initial voltage of the battery is more than 12.6V, the controller will cancel the constant voltage charging, when
the battery voltage rises to the constant voltage, it will directly start the floating charge stage.
ON/OFF Switch
Press for 2 seconds: ON/OFF
