About this product

SOLAR · MPPT CONTROLLER · 45A · COLD WEATHER
✓ Bluetooth Built-in✓ MPPT Technology✓ 150V Max PV✓ 45A Output✓ Cold Weather Rated
High-voltage MPPT controller for series panels and cold conditions — 150V max PV, 45A output

Manages high-voltage series solar arrays safely whilst delivering rapid 45A charging to your leisure battery bank. A generous 150V input threshold provides critical voltage headroom for series-connected panels, preventing sub-zero winter voltage spikes from damaging your system. Integrated Bluetooth enables precise wireless monitoring and customisable charging stages directly from your phone.

  • 150V max PV voltage — cold weather series panel ready
  • 45A output — handles large arrays (up to ~650W at 12V)
  • Built-in Bluetooth — VictronConnect app
  • MPPT — up to 30% more power than PWM
  • Series panel support — 4x 190W in series = 94V (safely under 150V)
  • Cold weather protection — VOC at -10°C still within range

⚡ Key Features

01Cold Weather Champion

At -10°C, panel VOC increases ~0.3%/°C below 25°C STC. 4x 190W in series = 94V STC, but ~104V at -10°C. The 150V limit handles this safely. A 100V controller would trip.

02Series Panel Support

Higher PV voltage means thinner cables and lower losses on long runs from roof to controller. Series connections are more efficient for larger arrays.

03Victron Tolerates Overcurrent

Victron controllers tolerate 30% overcurrent before damage, so 45A handles 58.5A max — covers 4x 190W (48.2A needed).

04BatteryLife Algorithm

Intelligent maintenance prevents the chronic undercharging that kills batteries in solar systems.
