Votronic's MPP-series solar controllers utilise Maximum Power Point Tracking (MPPT) technology to maximise the power harvested from your solar panel.  The MPPT technology continuously and automatically calculates the maximum power yield of the solar modules several times per minute with any surplus voltage from the solar panel being transformed into a higher charging current for the battery. This ensures short charging times and the best possible efficiency of your solar system under any given daylight conditions. MPPT-based controllers perform particularly well in low light levels and in overcast conditions.

This controller is fully automatic, maintenance-free and can be used with any 12V lead-acid (flooded, sealed, AGM, gel etc.) or LiFePO4 lithium battery and any solar panel (or combination of solar panels) with an output up to 250W, 15A and 50V DC.

The MPP-series controllers feature a second output so that some of the solar power can be used to trickle-charge a starter battery with a current of 1A max.

Works a treat

Have had this charger on our camper van for over 2 years. Changed to this one because starter battery went flat due to tracker drain (as insurance insist on tracker being on the vehicle battery).
This one keeps up with that and any radio usage whilst away in it as well as charging two 100ah leisure batteries with no headaches or faults at all.
