Best Charge Controllers Ranked

For RV and van owners running 500-700 W of panels on 12 V or about 1,400 W on 24 V. It has the same app and warranty as the smaller Victrons at a low cost per amp.

A strong default for 300-450 W van and RV arrays on 12 V. It is well priced for a five-year-warranty controller with a built-in app.

The pick for small van, trailer or boat systems with one or two panels. It costs little, has a polished app and a five-year warranty.

For large RV, cabin or boat systems that need 60 A and long series strings. Worth the premium if you want Victron’s app, BMS control and warranty.

A low-cost 40 A controller with app monitoring built in, for 12/24 V van and RV systems up to about 600 W.

The best all-round alternator charger for most vans and RVs with a 12 V lithium bank. It is small, very efficient and fully configurable from a phone.

For smaller vans and truck campers with a 100 Ah battery and a panel or two on the roof. Bigger banks or arrays need the 50 A DCC50S.

The value pick for vans and campers that want alternator and solar charging in one box. It costs well under half as much as a Redarc dual-input unit for more current.

A cheap, quiet way to add alternator charging to a van or camper with a lithium house battery. Pay more for Victron if you want built-in Bluetooth.

For boats and vans that need an isolated charger from a brand with a long track record. Buyers who don’t need isolation get more current and efficiency from the Orion XS.
