Charge Controller 30A DC-DC MPPT

An RV parks for the night at a campsite, no shore power socket in sight, and the road continues the next morning. This is exactly the everyday scenario the Charge Controller 30A DC-DC MPPT was built for: a charge controller that doesn't just manage solar, but taps every available energy source on the way.

Three sources, one battery. The Charge Controller 30A 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 the best source. No switching cables, no thinking required.

MPPT that keeps up. With an MPPT voltage range of 15 to 50V and up to 30A of PV input current, the Charge Controller 30A DC-DC MPPT draws the maximum from any solar panel, even under overcast skies or partial shading from trees at the campsite.

Two batteries, one app. For anyone who wants to keep starter and leisure batteries separate, the Charge Controller 30A 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 the road, not just the season. The multi-phase synchronous rectification buck-boost circuit design delivers high efficiency with low heat build-up. That pays off over years: less wear on components, stable charging power even with fluctuating vehicle bus voltage. For anyone using their vehicle season after season, not just one summer.

For campers and RVs: the alternator charges while driving, the solar panel takes over at the campsite, shore power completes the picture at the campground. The leisure battery is always full by evening.

For boats and off-grid setups: where shore power is rare and the sun is the main source, MPPT regulation 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, full control via app.
