Description
The Victron Energy BlueSolar MPPT 150/70-MC4 is a high-power fanless solar charge controller with industry-standard MC4 connectors, delivering 98% peak efficiency, ultrafast MPPT tracking, and advanced partial shading detection for large-scale off-grid solar installations.
Key Features:
- MC4 PV Connection — Equipped with two sets of industry-standard MC4 connectors for fast, tool-free solar panel string connections directly to the controller.
- Ultrafast MPPT Technology — Continuously tracks the true maximum power point, improving energy harvest by up to 30% over PWM controllers and up to 10% over slower MPPT controllers.
- Advanced Partial Shading Detection — Proprietary BlueSolar algorithm scans the full power-voltage curve to lock onto the optimum MPP even when multiple peaks exist due to partial shading.
- Fanless 98% Peak Efficiency — No cooling fan required, with maximum efficiency exceeding 98% and full rated output maintained up to 40°C.
- Eight Pre-Programmed Charge Algorithms — Selectable via rotary switch with full programmability to cover all major battery chemistries for immediate optimized use.
The BlueSolar MPPT 150/70-MC4 supports 12V, 24V, and 48V battery systems with automatic voltage detection, delivering 70A of rated charge current and handling up to 4,000W of PV power on 48V systems. The 150V maximum PV open circuit voltage allows flexible string configurations across a wide range of panel types.
An internal temperature sensor continuously compensates absorption and float charge voltages for ambient temperature changes, ensuring precise charging in all conditions. Real-time monitoring is available through Color Control GX or other GX devices, with Bluetooth access available via a VE.Direct Bluetooth Smart dongle.
Comprehensive electronic protection covers PV reverse polarity, PV reverse current, output short circuit, and over-temperature power derating for reliable long-term deployment. The IP43-rated blue enclosure operates across a wide -30°C to +60°C temperature range and meets international safety certifications including UL 1741 and CSA C22.2.
