1、LITHIUM BATTERY ACTIVATION AND STABLE CHARGING: Avoid controller crash and protect battery cells. When the battery is not powering the controller, power is drawn from the PV instead 2、ADAPT TO A VARIETY OF BATTERIES: Suitable for acid gel batteries, ternary lithium batteries, lithium iron phosphate batteries and other types of batteries 3、MULTIPLE PROTECTION FUNCTIONS: Solar reverse proof charging, battery reverse connection protection, battery open circuit protection, overvoltage and load overload protection, power failure protection, thunder protection 4、MPPT HIGH EFFICIENCY CHARGING: In any environment, the maximum power point of the photovoltaic array can be quickly tracked, the maximum energy of the solar panel can be obtained in real time, and the energy utilization rate of the solar system can be significantly improved 5、HIGH ENERGY UTILIZATION: Compared with the traditional PWM controller, the MPPT controller can exert the maximum power of the battery panel, so can provide a larger charging current. Generally speaking, the MPPT can increase the energy utilization by 15%~20% than the PWM controller Item Type: MPPT Solar Charge Controller Rated Current: 30A Photovoltaic Maximum Access Power: 24V: 30A-780W 48V: 30A-1560W Controller Takes Power: Battery or photovoltaic panel to take power Charging Method: MPPT charging function Load: A Variety of Working Modes Available: Pure light control mode, normally open mode, light control and time control mode (four periods and morning light) Protection Type: Solar battery reverse proof charging protection, battery open circuit protection, battery reverse connection protection, overload protection, etc. 1 x MPPT Solar Charge Controller 1 x User Manual
