Solar Charge Controller 12V 24V PWM 10A 20A 30A 40A 50A 60A Solar Panel Battery Regulator LCD Display Dual USB 5V Output The reverse order applies when deinstalling! An flawed sequence order can harm the controller! Connection 1 the battery to the charge regulator - plus and minus,double verify the relationship is good or now not 2 the photovoltaic module to the regulator - plus and minus double test the connection is good three Connect the consumer to the fee regulator - plus and minus double verify the relationship is right Deinstalling 1 the patron to the fee regulator - plus and minus 2 the photovoltaic module to the regulator - plus and minus 3 the battery to the charge regulator - plus and minus MODEL PWM-E-10A PWM-E-20A PWM-E-30A PWM-E-40A PWM-E-50A PWM-E-60A Battery Voltage 12V 24V Auto Charging Current 10A 20A 30A 40A 50A 60A Discharging Current 10A 10A 10A 20A 30A 30A Max Solar enter 48V(for 24V battery) 24V(for 12V battery) Equalization 14(Sealed) 14(Gel) 14(Flood) Float price 13(defaul,adjustable) Discharge stop 10(defaul,adjustable) Discharge reconnect 12(defaul,adjustable) Charge reconnect 13V Voltage of open gentle Solar Panel8V(Light lighting fixtures delay) Voltage of shut gentle Solar Panel8V(Light off delay) USB output 5V/3A Self-consume <10mA Operating temperature -35°C~+60°C Size 133*70*35mm 188*90*47mm *all pink shade voltage X2 ,while utilizing 24V formula this photo voltaic controller isn't waterproof, please set up it in indoor or out of the rain Features 1 business micro controller 2 LCD display,all adjustable parameter 3 4-stage PWM charge leadership four short-circuit protection,open-circuit protection,reverse protection,over-load defense 5 mosfet Reverse latest protection ,low warmth manufacturing This is very realistic type PWM solar controller ,it is small and lightweight ,you can use 12V and 24V Lead acid ,Gel,Sealed,Flooded,AGM Batteries can totally meet your place Photovoltaic system(including home lighting formulation )requirements PWM-E-10A , Max Voc : 24V (12V), 48V (24V); Max Power: 120W (12V), 240W (24V) PWM-E-20A , Max Voc : 24V (12V), 48V (24V); Max Power: 240W (12V), 480W (24V) PWM-E-30A , Max Voc : 24V (12V), 48V (24V); Max Power: 360W (12V), 720W (24V) PWM-E-40A , Max Voc : 24V (12V), 48V (24V); Max Power: 520W (12V), 1040W (24V) PWM-E-50A , Max Voc : 24V (12V), 48V (24V); Max Power: 650W (12V), 1300W (24V) PWM-E-60A , Max Voc : 24V (12V), 48V (24V); Max Power: 780W (12V), 1560W (24V)
