SRNE MA2440N15 MPPT Solar Controller pre built resulting in efficiencies of 50%

resulting in efficiencies of 50% or even less in solar systems where several days of reserve energy is required (battery operating in 70% to 100% charged state)

accommodating devices that may need extra power during startup

and durable IP32 enclosure for reliable performance

Note: these are not intended to extend to the bottom of the tank so the metal probes will actually be shorter than the tank depth options shown above
