Charge Controller 50A DC-DC MPPT

A large RV with air conditioning, a compressor fridge and multiple loads running needs more than a standard charge. This is exactly the higher demand the Charge Controller 50A DC-DC MPPT was built for: a charge controller that taps every available energy source, sized for 50A of charging power.

Three sources, full capacity. The Charge Controller 50A DC-DC MPPT charges from the vehicle alternator while driving, from the solar panel on the roof, and from shore power at the campsite. All three paths feed into one system that automatically prioritizes and handles up to 50A of PV input current.

MPPT for bigger setups. With an MPPT voltage range of 15 to 50V and up to 700W of PV input power, the Charge Controller 50A DC-DC MPPT is built for larger solar setups, the kind common on RVs with multiple roof panels or boats with high power demands.

65A generator input for backup. When sun and shore power aren't available, the generator input takes over with up to 65A, recharging the battery quickly even under poor conditions.

Two batteries, one app. For anyone who wants to keep starter and leisure batteries separate, the Charge Controller 50A DC-DC MPPT delivers smart battery management that cleanly isolates and monitors both circuits. Via the Bluetooth app, state of charge, voltage and current show up in real time on your phone.

Built for sustained load. The multi-phase synchronous rectification buck-boost circuit design delivers high efficiency with low heat build-up, even under the higher continuous 50A load. That pays off over years: less wear on components, stable charging power even with fluctuating vehicle bus voltage.

For large RVs: air conditioning, compressor fridge and multiple loads running at once, without the leisure battery running dry by evening.

For boats and high-demand off-grid setups: where shore power is rare, MPPT regulation up to 700W does the precision work, while CAN and Modbus interfaces allow integration into existing onboard systems.

For any dual-battery setup: anyone wanting to keep starter and service batteries cleanly separated gets the management built in, no extra device needed.

One controller, three charging sources, 50A of power controlled via the app.
