As shown as the right gure, the displaying number is the
protection voltage. And if the battery voltage is lower than
this voltage, the controller will disconnect the load loop to
prevent the battery from over-discharging.
At this interface, press button for long( 5 seconds),the
number starts to icker, and it means the controller enters into the interface ofsetting
the protection voltage.Use button to adjustthis parameter.
After nishing setting, press button for long ( 5 seconds) to exit this interface
and the controller can store this setting number.

protection state, and when the battery voltage recovers to
be higher than the recovering voltage, then the controller
will reconnect the load loop automatically.
At this interface,press button ( 5 seconds),thenumber

As shown asthe right gure, thedisplaying number is thevoltage of ceasing
charging. When thebattery voltage reaches upto this voltage, the controller
will disconnect the chargingloop to prevent thebattery from o vercharging.
After th e battery voltage drops, the controller will reconnectthe chargingloop.
At this interface, press button for long( 5 seconds),the number starts

Breakdown & disposal
If the screen shows as the right gure, it means thebattery
voltage is lower than the protection voltage. The controller
enters into the low voltage protection state and the load loop
disconnects. Use the solar panels or charger to charge for the
battery. When battery voltage recovers to the protection
voltage, the controller will recover to supply power for load,
and enter into the working state.
Low voltage protection & disposal:
V
If the screen shows as the right gure, and thelight ickers, it
mean the current of the load loop is 1.2 times ofthe rated current
within 3 seconds, and the controller is at overloading state.After
removing some loads, the controller will supply power to the
loads automatically within seconds, or you can press button to recover the
power supply compulsively.
Overloading protection & disposal:
If the screen shows as the right gure, and thelight ickers, it
means there happens short-circuit in the load loop, and the controller
is at short-circuit protection state. Please check whetherthe loads
are damaged and whether the connecting cables are short-circuit.
After eliminating the breakdown, press button to recover the power supply
for the loads.
Short-circuit protection & disposal:
Breakdown & disposal of solar panels:
Sign ickering means the controller do notdetect the existence of solar panels.
Please check whether the connecting with the solar panels is ingood condition, and
check whether the cables connecting the solar panels and the controller are i n
open-circuit condition.
If ickers when you turn onthe load, it means the starting impulsion current is
more than twice of the rated working current. Please restart the controllerfor times.
Other exceptional conditions:Please contact the distributor or manufacturer.
