Morningstar SunGuard solar regulator
£29
The SunGuard is the smallest controller we sell, suitable for solar panel systems delivering up to 54W. Tough and compact (it weighs a mere 90g and measures just 6 x 5 x 4 cm), it should keep your batteries in great condition for years. It comes with a 5 year manufacturer's warranty.
The tough outer case disguises sophisticated electronic circuits that regulate the solar voltage using pulse width modulation. PWM controllers maintain a higher state of charge in the battery bank than old-fashioned on-off regulators.
The SunGuard electronics are fully encapsulated in epoxy, so the SunGuard is completely weatherproof, and can be used in almost any location.
