Charge controller Victron SmartSolar MPPT 75/15 Bluetooth

Between your solar panel and your battery sits the component that decides charging time, yield and lifespan: the charge controller. Save here, and you waste sunlight. The Victron SmartSolar MPPT 75/15 is built for everyone who refuses to do exactly that — in the camper, on the boat, at the garden shed or in an off-grid setup.

MPPT. The top class of charge controllers. Maximum Power Point Tracking is the premier league of solar charging. A microprocessor determines the optimal operating point of your module several times per second and converts surplus voltage into additional charge current. The result isn't a marketing promise but physics: shorter charging times and the best possible yield from every hour of sun. Where simple PWM controllers leave yield on the table, the MPPT brings it into the battery.

Bluetooth is already built in. No extra module, no cable. The SmartSolar communicates out of the box. With the free VictronConnect app you read yield, state of charge and history straight on your phone — and set the controller to your battery in a few taps. Full control, no tools, no cable clutter.

For every battery you run. Lead-acid, AGM, GEL or lithium — the SmartSolar 75/15 charges them all with the right profile. You pick your battery type in the app, and the controller applies the matching charge program. That way you get maximum capacity while protecting your battery's lifespan.

Wired right, full power. On a 12 V battery you run at least one 12 V panel, ideally two 12 V panels in series or one 24 V panel, at most three 12 V panels in series. Important: mind the open-circuit voltage of your panels — it must never exceed 75 V. The controller delivers up to 15 A charge current reliably, for both 12 V and 24 V systems.

Camper and motorhome. More yield on every drive, a full battery by evening — and the app showing what the roof is producing in real time.

Boat and off-grid. Rugged charging that squeezes the maximum from a small area. Where every amp-hour counts, MPPT plays to its strength.

SmartSolar. By Victron. For decades Victron has stood for charging technology that doesn't fade under hard, continuous use. We supply it as your Swiss specialist retailer, with advice that fits your setup. Quality you notice at the battery.
