50A Advanced MPPT Solar Charge Controller | SunStar

Supplier: Soanar

The SunStar 50A Advanced MPPT Solar Charge Controller includes a full, four-stage battery charging station.

Price Guide: POA

A true commercial grade MPPT solar charge controller from Rich Electric, with a whole host of features to suit almost any system. Features high grade maximum power point tracking to provide maximum efficiency in converting solar generated power into battery charging. With a wide solar (PV) input voltage range and ability to charge either a 12V, 24V, 36V or 48V battery, this MPPT controller can be used in any number of different system applications. The two auxiliary relay outputs can also be configured to do such tasks as start up a generator with remote start, or control a dump load so that you can also incorporate a wind generator into the system. With the ability to parallel stack up to 16 units, they can even be applied to solar arrays up to 50kW! See user manual on website for full features and specifications.
