Morningstar Sunguard SG-4

Very compact solar charge controller for industrial use, the Morningstar SunGuard is the world's leading single module controller. Solar charge controllers or regulators should be used to prevent battery damage due to overcharging or deep discharge. The Morningstar SunGuard controller is designed for simplified installation and can be used with gel, AGM (absorbed glass mat), encapsulated, and non-encapsulated lead acid batteries. The SunGuard utilizes advanced PWM (pulse width modulation) charge control for constant voltage charging. A true PWM cycle from 0 to 100% is very fast and stable, ideal for efficient battery charging. The device can be mounted inside or outside as the cables are Hypalon insulated.
