Charge Controllers

GF CHARGE CONTROLLER

The GF charge controllers are designed to withstand the toughest weather conditions while providing a long service life of battery charge regulation. With a single knob control and 4 indicator lights and an easy to access terminal connector strip, the operation of the GF series controllers requires no technical background. Its durable, aluminum case, water resistant construction, reverse polarity protection and ability to withstand temperatures from -40 deg. C (or F) allows exterior mounting with only minimal sheltering so that the least amount of wiring is required for your PV power regulation needs.

All GF series controllers come with a standard DC current diversion feature allowing excess source current to be used in auxilliary applications, coupled with unmatched efficiency due to minimal source - load voltage drop and a 9 milliampere circuit current draw even during full capacity charging.

The GF series controller is an excellent choice for multilingual applications as no complex display screens or menus are used for its adjustment or reading battery condition. Operating manuals are available in most languages upon request.
