SRNE MPPT Solar Charge Controller Makes Your Energy Management More Efficient!

Advanced Maximum Power Point Tracking

This serie controller adopts the industry-leading MPPT which tracking efficiency up to 99.9% to achieve the maximum energy trackingfor the solar panel, that is, it can quickly and accurately track the maximum power point of the solar battery on any condition.

Temperature Sampling and Control

Fitted with a Remote Temperature Sensor, the MPPT Charge Controller can measure battery temperature in real-time. Connect the temperature sensor to the corresponding temperature interface to achieve the high and low temperature protection for the battery and the temperature compensation for the charging voltage of lead-acid battery (no temperature compensation for the lithium battery) , assuring stable and constant charging.

Support TTL & RS485 Communication

MPPT solar charge controller has powerful TTL and RS485 communication protocol function. By connecting the controller with other devices, you can easily obtain the status information of the charger, adjust battery charging parameters, etc.

Intelligent Protection Functions

MPPT provides multiple protection functions: Over-temperature protection of device, Battery over-temperature protection, Input over-power protection, PV input side too high voltage protection, PV input reverse-connection protection, Reverse charging protection at night.

Max. Solar Input Power 12V/260W 24V/520W

The MPPT charge controller can work with standard off-grid 12/24V solar panels. In particular, this controller will significantly increase the efficiency of a solar system where the solar panel voltage is much higher than the battery voltage.
