SmartSolar MPPT 250V/70A-Тr — is a flagship, high-power charge controller from Victron Energy. The device is designed to work with extremely high voltages of solar arrays (up to 250 V DC) and is capable of generating an impressive charging current of up to 70 A. This makes it an ideal solution for creating efficient solar power plants in 12 V, 24 V, and 48 V systems.
The device is equipped with a built-in Bluetooth module, a VE.Direct communication port, and a programmable relay. The controller has flawless compatibility with advanced LiFePO4 storage devices and easily integrates into the GX ecosystem (Cerbo, Ekrano) for centralized management. The model is designed to cover the needs of the industrial, commercial, marine, and powerful domestic segments, where reliability and uncompromising efficiency come first.
Main Advantages of the SmartSolar Tr Controller
- Innovative MPPT tracker — the coefficient of performance reaches a benchmark 98%
- Colossal charging power — current generation up to 70 A
- Support for long PV strings — input voltage from solar panels up to 250 V
