Detailed overview: Victron SmartSolar MPPT 150/35 charge controller
The Victron SmartSolar MPPT 150/35 is a premium solar charge controller from Victron Energy, built for setups that step up in voltage. Its 150/35 designation means it accepts up to 150V of solar (PV) input voltage and delivers 35A of charge current, on 12V, 24V, or 48V battery systems (36V available via software configuration), with automatic battery voltage detection.
This 150V rating changes how a setup gets wired: it allows several solar panels to be wired in series (a string) rather than in parallel, which cuts line losses over long cable runs and allows thinner cable gauges. It's the only controller in our range able to accept this kind of wiring, where our BlueSolar 75/15 and SmartSolar 100/20 remain capped at 75V and 100V.
Its ultra-fast MPPT technology continuously tracks the optimal power point of the panels and harvests up to 30% more energy than a conventional PWM controller, with efficiency reaching up to 98%. In practice, it handles up to 500W of panels at 12V, 1000W at 24V, 1500W at 36V, and 2000W at 48V. It works with every major battery chemistry, lead-acid AGM, gel, flooded, and lithium LiFePO4, thanks to its 8 pre-programmed charge algorithms plus a fully customizable one.
Built-in Bluetooth lets you use the VictronConnect app to track output in real time, review the 46-day history, and adjust every setting with no extra dongle. A wired VE.Direct port is still available for integration into a wider Victron system (Cerbo GX, remote VRM monitoring). The IP43-rated case handles everyday use in an RV or off-grid site well, though it isn't built for permanent outdoor exposure.
It weighs 2.8 lb (1.25 kg) at 7.3 x 5.1 x 2.8 in (186 x 130 x 70 mm), backed by a generous 5-year warranty for this kind of hardware. Its price sits above entry-level controllers, but that's justified by Victron's reliability, Bluetooth monitoring, and above all the unique ability to wire panels in series at high voltage. For a van, boat, or off-grid solar setup that outgrows a 100V controller, the SmartSolar 150/35 is a benchmark choice.

The SmartSolar 150/35 stands out for its 150V PV rating, which allows several panels to be wired in series, unlike the SmartSolar 100/20 and the Renogy Rover 40A, both capped at 100V and parallel wiring. Against the EPEVER Tracer 3415AN, also rated at 150V, Victron keeps the edge with standard built-in Bluetooth (no separate module needed) and proven build quality. The Renogy Rover 40A offers more current for large 100V setups, but doesn't step up in voltage. For a build that goes beyond 100V PV, the SmartSolar 150/35 remains the safest pick.

Our tester's review: Julien De Jurquet
You install the SmartSolar 150/35 once a plain 75V or 100V controller becomes too tight for the build. On a van with two 200W panels wired in series rather than parallel, the gain is immediate: less loss in the wiring, a thinner cable gauge does the job, and the controller keeps tracking the maximum power point without a hitch, even under a hazy sky. Built-in Bluetooth is a genuine everyday plus, the VictronConnect app shows live output, a 46-day history, and lets you tweak charge thresholds with no cover to open. Victron's build quality inspires confidence, and the case doesn't run hot even under full load. The real downsides: the price sits well above a plain PWM controller or a budget Chinese MPPT, the IP43 rating means it needs shelter from direct spray, and Amazon hides the checkout price until it's in your cart, worth a quick check before you commit. But for a build that goes beyond 100V PV, this is one of the safest picks on the market today.
Frequently asked questions: Victron SmartSolar MPPT 150/35 charge controller
A 150V PV rating lets you wire several panels in series (a string) rather than in parallel. Current flowing through the cables is lower, cutting line losses and allowing a thinner cable gauge over long runs between the panels and the controller.
It handles up to 500W of panels on a 12V system, 1000W at 24V, 1500W at 36V, and 2000W at 48V. Solar input voltage must not exceed 150V (145V maximum at start-up).
Yes. It offers 8 pre-programmed charge algorithms covering lead-acid AGM, gel, flooded batteries, and lithium LiFePO4, adjustable and fully customizable from the VictronConnect app.
The 100/20 is capped at 100V PV and 20A, enough for one or two panels in parallel. The 150/35 steps up to 150V and 35A: it's the only one able to accept several panels wired in series, for a more powerful setup or long cable runs.
The controller has built-in Bluetooth: the VictronConnect app shows live output and a 46-day history. A wired VE.Direct port also allows integration into a Victron GX system for monitoring via the VRM portal.
