MPPT Solar Charger Controller 40A 30A 20A12V 24V Solar Panel Controller LCD Display Various Load Control Modes Support Li

Thank you for selecting MPPT series solar charge controller with the most advanced MPPT control algorithm and the maximum power point of the pv array can be quickly tracked in any environment so that it can get the maximum energy from the solar panel and significantly improve the utilization of energy in solar system. The machine has the dual display function of LCD and Remote header (optional) and standard communication interface, convenient for user extension application and satisfy different monitoring needs to the maximum extent. It can be used in communication base station, home power supply system, traffic light, solar street lamp, courtyard lamp systems, etc.

Feature：

● Advanced MPPT maximum power point tracking technology, the tracking efficiency is no less than 99.5%.

● High quality components are used to improve the system performance, and the maximum conversion efficiency can reach97%.

● Super fast maximum power tracking speed while ensuring tracking efficiency.

● Accurate identification and tracking of the maximum power point of multi-wave peak.

● Reliable maximum input power of pv array to ensure the safety of equipment.

● Wide pv array maximum power point operating voltage range.

12/24v automatic voltage identification

● The LCD is designed to dynamically display the operation data and working status of the equipment.

● Various load control modes: general mode, light control mode, dual time mode, pure charger mode and timing mode.

● Seal, GEL, Flooded, LifePO4 and Li(NiCoMn)O2 charging process can be selected.

● The function of battery temperature compensation.

● Power statistics recording function.

● External display unit and other peripherals, realize real-time data view and parameter setting function.

Kind tips: The controller will start PWM function at high voltage disconnection (HVD) voltage point, which limits voltage rising to protect battery.
