The SunGuard 4 12 volt controller offers most of the same features of the ProStar line, but without the battery status LED's, automatic equalization or the optional LCD display. The SunGuard 4 is a PWM controller and can control up to 4.5 array amps (can be paralleled for 40 amps or more). The SunSaver's advanced design delivers outstanding performance and value.
SunSaver's low cost is made possible by Morningstar's unique approach to design and manufacturing: automated production, latest power electronic power technologies, latest control and logic technologies, and high volume manufacturing.
