Giantz 40A MPPT Solar Charge Controller 12V–48V

Overcharging a battery bank is one of the quickest ways to shorten its life — especially when you're relying on solar power off-grid at camp, in a caravan or on a remote property. The Giantz 40A MPPT Solar Charge Controller takes the guesswork out of solar management, automatically detecting your system voltage and regulating charge across 12V, 24V, 36V and 48V setups.

With up to 99% MPPT tracking accuracy and up to 97% maximum charging efficiency, it squeezes the most out of your solar panels and keeps your batteries in better health over the long run. The backlit LCD display makes it easy to monitor system status, while built-in protection covers overcharge, reverse polarity, overloading and overheating — so your setup stays safe even when conditions change.
