Victron SmartSolar MPPT 150/35 Solar Charge Controller | SCC115035210

The Victron SmartSolar MPPT 150/35 is a solar charge controller built for off-grid and battery-based solar systems. It accepts a maximum PV open-circuit voltage of 150V and delivers up to 35A of charge current, making it suited to residential, commercial and mobile off-grid installations that need accurate battery charging.

Charge controller for solar panel arrays

The 150/35 rating means the controller can accept panel strings with a combined open-circuit voltage of up to 150V, allowing series-connected arrays without a separate combiner. The 35A output suits battery banks common in off-grid cabins, narrowboats, campervans and small commercial sites. Its MPPT algorithm tracks the maximum power point as irradiance changes, which matters given frequent cloud cover and partial shading.

Key features

• PV input, accepts strings up to 150V open-circuit.
• Charge current, up to 35A.
• Bluetooth, built in, configured through the VictronConnect app without extra hardware.
• Battery compatibility, works with lithium (LiFePO4), AGM, gel and flooded batteries.
• Load output, supports direct DC load control.
• VE.Direct port, connects to Victron GX devices, the MPPT Control display and other Victron components.
• Weight, 1.4 kg.

Applications

Fits off-grid residential systems on 12V, 24V or 48V battery banks, narrowboat and marine installations, campervan and motorhome setups needing Bluetooth monitoring, and remote telecoms or agricultural equipment run from solar. It also integrates into small commercial off-grid systems built around the wider Victron range.

Installation notes

Fitting should be carried out by a qualified electrician or experienced installer. PV string open-circuit voltage must stay under 150V at all times, including the increase seen in cold weather. Battery chemistry and voltage should be checked in VictronConnect before commissioning, and any grid-connected or larger integrated system should follow current UK wiring regulations and G98/G99 requirements where relevant.
