Description Advanced maximum power point tracking (MPPT/PWM) technology, the efficiency is not less than 99.5%. High-quality components improve the system performance, and the maximum conversion efficiency is 98%. Super fast tracking speed and guarantee tracking efficiency.Large screen LCD display, charge and discharge current display, cumulative power generation and discharge power query, temperature display, light control + delay control; adjustable charge and discharge parameters, with power-off memory and other functions.Dual USB output, the maximum current is 2.5A. Equipped with all necessary protection devices, the control parameters of the system are adjustable, easy to set up and operate. Built-in overheating, overcurrent, short circuit, open circuit protection, fault elimination, controller automatic recovery. Two-way MOS tube anti-backflow circuit, high-power charging mode, ultra-low heat.Built-in short circuit protection, open circuit protection, reverse connection protection, overload protection. Reverse current protection, low calorific value, with self-recovery function, will not damage the controller.Real-time display of temperature, charging current and discharge current. Current autofocus MPPT tracking charging, high charging efficiency, charging process does not stop detection, two-way focus tracking.Name: LCD screen solar controllerVoltage: DC 12V / 24VDisplay: LCD screenSelf-consumption: less than 10MAOvercharge protection: 14.4V / 28.8VOvercharge Float charge: 13.7V / 27.4VCharge recovery voltage: 12.6V / 25.2VOver discharge protection: 10.7V / 21.4VOver discharge recovery: 12.6V / 25.2VWorking temperature: -35 Celsius -60 Celsius12V fits 18V solar panel, 24V fits 36V solar panel12.0 volt lead acid battery correspondingThe float voltage is set to: 13.6 The recovery discharge voltage is set to: 12.6The discharge cut-off voltage is set to: 10.712.8 volt lithium iron phosphate battery correspondingThe float voltage is set to: 14.6The recovery discharge voltage is set to: 13.6The discharge cut-off voltage is set to: 11.011.1 volt lithium battery correspondingThe float voltage is set to: 12.6The recovery discharge voltage is set to: 11.6The discharge cut-off voltage is set to: 9.6The minute is adjustable when the output is turned off, which is more convenient (there is no adjustment when the market is only available).PV system power Description:100A battery 12V photovoltaic system: power is 650W100A battery 24V photovoltaic system: power is 1300Wcolour: orangeMaterial: Plasticsize: 133x70x35mmPackage Contents:1 x 100A Solar ControllerOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
