Victron - Model MPPT 75/15 - Solar Controllers - Brochure

Victron MPPT 75/15 Controller – Maximum power point tracking (MPPT) is a technique solar charger controllers use to get the maximum possible power from one or more solar panels. Solar cells have a complex relationship between solar irradiation, temperature and total resistance that produces a non-linear output efficiency which can be analysed based on the I-V curve. It is the purpose of the MPPT system to sample the output of the cells and apply the proper resistance (load) to obtain maximum power for any given environmental conditions.
