4-Stage charging(Boost, ABS, Equalization,Float),and equipped with industrial-grade STM 8 microprocessor to prolong your battery life cycle.Dual USB can give your electronic product max 5V 2.5A. This solar controller backlight display PV/Battery/Load charge and discharge parameter. like the fourth picture, adjustable Floating voltage/LVD/LVR/Timer according needs with with power-off-memory function. This solar charge controller fit for Lead-acid batteries(OPEN,AGM,GEL) with mutiple load timer.Load should be DC. For protecting the lifespan of your battery, once the voltage of the battery drop below 8V, the solar controller will turn off automatically. Eight PWM charge controller Protection:Power off memory /Dual MOSFET Reverse current /over heat /Under-voltage discharge /short-circuit /open-circuit / over-load /over-charging protection.more safe for home, industrial,commercial etc. The battery positive and negative pole according to the icon access controller,the control er will automatically detect the battery voltage,the load positive and according to the icon access controller,pay attention not to negative pole answer,the solar panel according to the icon access controller. please strictly follow the above order to access,otherwise it may damage the controller or other components; the disassembly sequence is contrary to the wiring order. 12V system with 17.5V solar panels,24V system with 36V solar panels.
