Morningstar 4.5 amp Control (DEMO)


Morningstar Sunguard charge controller


Very Small charge controller for a single panel and small battery. Constant voltage, pulse width modulation. Regulates to constant 14.1 volts with temperature compensation. Six milliampere internal power consumption. No meter included. These are the best for fence chargers, small boats, radio repeater sites and other small unattended projects. Has wire leads, 2 solar, 2 battery. Not recommended for residential power system, because adding appropriate meters brings total cost higher than other small residential controls. Epoxy potted and sealed. 12 Volt Only.

We’ve seen the SunGuard installed as a controller in an out-building lighting system among other uses. Great little basic charge control for up to a single 65 watt, 12 volt solar panel.
