INVERTER PV (Fronius Eco 25.0-3-S) 25kVA 580/850V

The inverter transforms the direct current generated by the solar modules into alternating current. This alternating current is fed into the electric grid synchronously with the grid voltage.

A solar inverter converts the direct current (DC) produced by solar photovoltaic modules into alternating current (AC) synchronized with the grid. Designed for grid-connected systems, it continuously monitors voltage, frequency, and grid stability to ensure safe operation. It starts feeding power into the grid when solar input is sufficient and disconnects automatically during abnormal conditions. The inverter maximizes energy yield using MPPT and reduces output if it overheats to protect internal components.

The inverter has been developed exclusively for use in grid-connected photovoltaic systems.
