Detailed description
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.
