MPPT solar charge controller 12V-250W

The MPPT250 solar charge controller is a high-end product. It incorporates a sophisticated optimal energy conversion algorithm, called MPPT (Maximum Power Point Tracking) designed to maximize energy storage from the photovoltaic generator. The MPPT constantly monitors the operating constants of the PV generator to ensure it remains at its maximum energy conversion point. This technology becomes an advantage in all sunlight conditions, especially in cloudy regions with variable climates where these sunlight conditions change from moment to moment. The solar energy conversion efficiency can be increased by up to 50% more compared to a classic controller.

This MPPT 12V-250W model converts the maximum energy from a PV generator to provide the maximum available current for battery charging. During charging, it controls the battery's charging voltage and current and the discharge current based on the amount of energy available from the PV generator and the battery's state of charge. Additionally, it operates over a wide input voltage range from the PV generator and offers increased flexibility to installers in choosing PV modules and their configuration.
