Victron BlueSolar MPPT 150/70-Tr: High-Capacity Solar Charge Controller for 12V, 24V, and 48V Systems

Efficient Energy Harvesting with Ultra-Fast MPPT Technology

The Victron BlueSolar MPPT 150/70-Tr is a robust, non-Bluetooth solar charge controller engineered for demanding off-grid and mobile power systems. Its ultra-fast Maximum Power Point Tracking (MPPT) algorithm continuously adjusts to changing light conditions, boosting energy yield by up to 30% compared to traditional PWM controllers and up to 10% over slower MPPT designs. This is particularly valuable under intermittent cloud cover, where rapid response ensures your batteries receive maximum available power.

With a rated charge current of 70 A and support for 12 V, 24 V, and 48 V battery banks (auto-select), this controller handles substantial solar arrays—up to 1000 W at 12 V, 2000 W at 24 V, and 4000 W at 48 V. The 150 V maximum PV open-circuit voltage allows flexible series string configurations, reducing wiring costs and voltage drop in larger installations.

Advanced Partial Shading Performance

Partial shading from trees, antennas, or nearby structures can create multiple power peaks on a solar array’s voltage curve. Conventional MPPT controllers often lock onto a local peak, missing the true maximum power point. The BlueSolar’s innovative algorithm scans the entire curve to consistently find the optimal MPP, maximising energy harvest even in challenging shading scenarios. This makes it an excellent choice for installations where shading is unavoidable, such as on vehicle roofs or in built-up areas.

High Efficiency and Reliable Thermal Design

With a peak conversion efficiency exceeding 98%, the BlueSolar MPPT 150/70 minimises energy losses during charge regulation. Its fanless design relies on a substantial aluminium heatsink for cooling, ensuring silent operation and reducing maintenance. The controller delivers full rated output current up to 40 °C, with automatic power derating at higher temperatures to protect internal components. This thermal resilience is critical for installations in hot Australian climates, where enclosed compartments can reach extreme temperatures.

Flexible Charge Control and Battery Protection

The controller features a fully programmable charge algorithm via VE.Direct, allowing customisation of absorption, float, and equalisation voltages to suit various battery chemistries. For quick setup, eight pre-programmed algorithms are selectable via a rotary switch. An internal temperature sensor automatically compensates charge voltages, preventing overcharge in hot conditions and undercharge in cold environments—essential for prolonging battery life.

Comprehensive electronic protections include:

• PV reverse polarity and short circuit protection
• PV reverse current blocking at night
• Output short circuit and over-temperature safeguards

These features reduce the risk of system damage from wiring errors or environmental extremes, offering peace of mind for critical off-grid applications.

Monitoring and Integration Options

While this BlueSolar model does not include built-in Bluetooth, it is equipped with a VE.Direct communication port for wired data connections. You can add wireless monitoring by pairing it with the VE.Direct to Bluetooth Low Energy dongle (sold separately), enabling real-time data display on smartphones or tablets via the VictronConnect app. Alternatively, connect to a Color Control GX panel or other GX devices for comprehensive system monitoring and remote management via the VRM portal.

Built for Harsh Environments

The BlueSolar MPPT 150/70 is housed in a rugged enclosure with an IP43 rating for electronics (IP22 for the connection area), protecting against water spray and solid objects. The large screw terminals accept cables up to 35 mm² (AWG2), ensuring secure, low-resistance connections for high-current wiring. Its compact dimensions (185 x 250 x 95 mm) and integrated mounting flange allow straightforward installation in tight spaces, such as motorhome battery compartments or marine engine rooms.

Ideal Applications

This controller is well suited for:

• Large off-grid solar systems for homes, cabins, and remote sheds
• Marine and RV installations requiring high charge currents
• Industrial and agricultural solar pumping systems
• Telecommunications and remote monitoring stations

Its ability to handle high PV voltages and currents makes it a scalable solution for expanding energy demands.
