Overview

HV configuration. The Victron 250/70 Solar Inverter PSW is engineered for efficient solar power conversion in Uganda’s diverse grid and off-grid settings. Operating at 4kVA and supporting 48V low voltage (LV) single phase systems, this inverter integrates advanced MPPT charge control for optimal energy harvest from solar arrays. Its adaptive multi-stage charging algorithm accommodates a range of battery voltages (12/24/36/48V), with automatic selection for most configurations. The inverter is equipped with comprehensive protection features, including PV reverse polarity, output short circuit, and over-temperature safeguards. Data communication is enabled via VE.Can, VE.Direct, and Bluetooth, supporting remote monitoring and parallel operation for scalable installations. Designed for indoor, unconditioned environments, the Victron 250/70 meets international safety standards and is suitable for professional solar installations across Uganda.
