Research of domestic photovoltaic charging system with maximum power point tracing(MPPT)

In order to prolong life of storage cell in domestic photovoltaic system and improve performance of this system, the paper developed a domestic photovoltaic charger, and in design of this charger proposes, a kind of charging control method, the maximum power point tracing (MPPT) of photovoltaic array conjointed with temperature compensation to charging voltage for storage cells, was developed. The results of experiment and simulation show that this system can control photovoltaic array by MPPT and achieve temperature compensation required by charging for storage batteries.
