Detailed description

The Victron Energy BlueSolar MPPT 250/70-Tr VE.Can is a solar charge controller designed for large-scale photovoltaic (PV) installations, operating on 12V, 24V, and 48V battery systems. It features ultra-fast maximum power point tracking (MPPT) technology to optimize energy harvesting from solar panels, particularly during changes in lighting conditions or partial shading.

Performance and Efficiency

This controller delivers a maximum charge current of 70A and supports a maximum PV open-circuit voltage of 250V. It automatically detects battery system voltage (12V, 24V, or 48V) and can handle PV power up to 1,000W for 12V systems, 2,000W for 24V systems, and 4,000W for 48V systems. Its peak conversion efficiency exceeds 99%, ensuring optimal use of solar energy. The BlueSolar MPPT 250/70-Tr VE.Can is equipped with a multi-stage adaptive charging algorithm, fully programmable, with eight pre-programmed options selectable via a rotary switch. Its proprietary algorithm provides advanced partial shading detection by scanning the power-voltage curve to find the maximum power point even in the presence of multiple peaks.

Connectivity and Protection

VE.Can communication allows synchronization of up to 25 units for multi-controller solutions and centralized monitoring when connected in series to a Victron GX device (such as a Color Control GX). Remote monitoring and control are possible via the VictronConnect app (with an optional Bluetooth dongle) or the Victron Remote Management (VRM) portal via an internet-connected GX device. The controller includes extensive electronic protection against overheating, power derating at high temperatures, PV short-circuit, PV reverse polarity, and PV reverse current. It features an internal temperature sensor for charge voltage compensation, a programmable relay that can be configured for alarms or user-defined events, and a 2-pole remote on/off connector for integration with systems such as a VE.BUS BMS. Its fanless design ensures silent operation, and its protection rating is IP43. It is equipped with screw terminals for PV connections. Its dimensions are 185 x 250 x 95 mm and it weighs 3.00 kg. It operates in a temperature range from -35 °C to +60 °C.

« Technical analysis of the BlueSolar MPPT 250/70-Tr VE.Can solar charge controller for large installations »

The BlueSolar MPPT 250/70-Tr VE.Can charge controller is a robust solution for marine and land-based solar installations requiring significant power management. Its ability to operate on 12V, 24V or 48V battery voltages makes it adaptable to a wide range of applications, including solar systems for recreational vehicles, marine applications, residential installations, and off-grid systems.

The integration of VE.Can communication is a major asset for complex installations. It enables not only synchronization of up to 25 units but also centralized monitoring and control via a Victron GX device, such as a Color Control GX. This feature is essential for large solar farms where modularity and redundancy are critical. The proprietary algorithm system for advanced partial shading detection ensures consistent performance, even in environments where panels may be obstructed—a common scenario in marine environments.

While remote monitoring is possible via the VictronConnect app, adding a Bluetooth dongle is required for direct connection, or a GX device for full management via the VRM portal. Its fanless design ensures silent operation, a significant advantage for installations in inhabited areas, and its IP43 protection makes it resistant to water splashes. However, it is not designed for prolonged direct exposure to harsh weather or immersion.
