Description
The Victron Energy BlueSolar MPPT 150/35 is a high-efficiency fanless solar charge controller with ultrafast maximum power point tracking and advanced partial shading detection. It delivers 98% peak efficiency across 12V, 24V, and 48V battery systems for demanding off-grid solar installations.
Key Features:
- Ultrafast MPPT Technology — Continuously tracks the true maximum power point to improve energy harvest by up to 30% over PWM controllers and up to 10% over slower MPPT controllers in all light conditions.
- Advanced Partial Shading Detection — Proprietary BlueSolar algorithm scans the full power-voltage curve to always lock onto the optimum MPP, even when partial shading creates multiple power peaks.
- Fanless 98% Peak Efficiency — No cooling fan required, with maximum efficiency exceeding 98% and full rated output maintained up to 40°C without derating.
- Eight Pre-Programmed Charge Algorithms — Selectable via rotary switch with full programmability, covering all major battery chemistries for immediate out-of-the-box use.
- Internal Temperature Sensor — Automatically compensates absorption and float charge voltages for ambient temperature to ensure accurate, battery-safe charging at all times.
The BlueSolar MPPT 150/35 supports 12V, 24V, and 48V battery systems with automatic voltage detection, delivering 35A of rated charge current. It handles up to 500W on 12V, 1,000W on 24V, and 2,000W on 48V systems with a 150V maximum PV open circuit voltage.
Real-time data monitoring is available through Color Control GX or other GX devices for wired system integration. Bluetooth access is available via a VE.Direct Bluetooth Smart dongle for wireless smartphone monitoring and configuration.
Comprehensive electronic protection covers PV reverse polarity, PV reverse current, output short circuit, and over-temperature power derating. The IP43-rated blue enclosure operates across a -30°C to +60°C temperature range and meets international safety certifications including UL 1741 and CSA C22.2.
