SUNGUARD CONTROLLER

MORNINGSTAR SUNGUARD SG 4 CHARGE REGULATOR

SunGuard’s technology provides exceptional reliability, pulse width modulation (PWM) battery charging and consistent high quality. The SunGuard™ uses the same charging circuit and the same high quality components as the SunSaver™. It is ideal where a 12 V, high quality, low power regulator is needed. It can control up to 4.5 A of PV module output. This is ideal for single module systems of 75 W or less. There are 4 wires for connectionto module and battery wiring.
