Couldn't load pickup availability
The Victron SmartSolar MPPT 150/35 is the entry to the 150V family — same 35A charge current as a 100/35 would deliver, but with 150V max PV input. That higher voltage headroom is what you need for residential-grade 60-cell or 72-cell panels (which have Voc above 35V each), longer panel strings, and cold-climate installs where Voc spikes. Works on 12V, 24V, 36V, or 48V battery banks.
Solar array sizing
| Battery bank | Maximum solar array | Typical setup |
|---|---|---|
| 12V | ~500W | 2× 280W residential panels in series |
| 24V | ~1000W | 3× 330W residential panels (series-parallel) |
| 48V | ~2000W | 4–6× residential panels in series strings |
Maximum PV open-circuit voltage: 150V. This is the threshold that unlocks residential-grade panel use without needing parallel-only wiring.
Why pick a 150V controller?
- Residential panels in series — 60-cell panels have ~40V Voc; two in series is 80V; safe well under 150V even in cold weather.
- Longer cable runs — higher-voltage strings lose less power to wire resistance.
- Cold-climate safety margin — panel Voc spikes 25%+ in sub-freezing weather; the 150V headroom keeps you well clear of damage.
- Lower amps for given watts — higher-voltage strings let you use thinner gauge wire.
Why the SmartSolar 150/35
- Ultra-fast Maximum Power Point Tracking — Victron's algorithm responds in milliseconds to changing cloud and shading conditions.
- Built-in Bluetooth — pair directly with VictronConnect on iPhone or Android.
- 98% conversion efficiency — natural convection cooling, no fans.
- VE.Direct port — connect to Cerbo GX for VRM Portal, or chain with SmartShunt / BMV-712.
- Automatic battery voltage detection — 12V, 24V, 36V, 48V.
- Multi-stage adaptive charging — AGM, Gel, Flooded, LiFePO4 profiles preconfigured.
- Optional remote temp sensor — sold separately for battery temperature compensation.

Recommended applications
- Off-grid cabin with residential panels — 24V or 48V system with 2–3 residential 280–400W panels
- RV / Marine with high-Voc panels — longer panel strings, lower amps, thinner cable
- Cold-climate solar — anywhere panel Voc spikes in winter
- 48V backup systems — mid-size battery backup with 1500–2000W of solar
- Commercial telecom — remote tower or cabinet solar
