SRNE ML2440 MPPT Solar Charge Controller 40A 12/24V

Maximise solar energy efficiency

The SRNE ML2440 MPPT Solar Charge Controller, also known as a solar regulator, is essentially a solar battery charger connected between the solar panels and battery. It regulates the battery charging process and ensures the battery is charged correctly, or more importantly, not over-charged.

The SRNE ML2440 MPPT Solar Charge Controller can also be connected to an external LCD screen or Bluetooth module so that users can not only check operating data and status but also modify the controller parameters. It’s perfect for RV systems and solar power systems.

Advanced tracking technology
Advanced dual-peak or multi-peak tracking technology. When the solar panel is shadowed or part of it breaks down, multiple peaks of the I-V curve will occur. The controller is still able to accurately track the maximum power point. The maximum power point tracking algorithm can significantly improve the energy utilization efficiency of photovoltaic systems. The charging efficiency is 15% to 20% higher than the conventional PWM method.
