MPPT Solar Regulator Carspa MH-R2440, 12/24 V, 40 A

Product detailed description

Professional MPPT controller for charging 12/24 V lead and LiFePO4 batteries with solar energy. Compared to cheaper PWM controllers, MPPT technology achieves significantly higher efficiency (up to 98 %) and ensures maximum utilization of energy from solar panels.

The controller supports sealed batteries of AGM, GEL and LiFePO4 types, and automatically recognizes the system voltage. On the clear LCD display you can easily view the panel and battery voltage, charging current, state of charge, load consumption, temperature or error code in case of a fault. A temperature sensor is included with the controller for charging compensation.

You can switch the connected DC load manually or according to a program, for example at dusk with a timer. An advanced protection system protects the controller, solar panels and battery from damage and incorrect wiring.
