Inverter solare ei-tre

Three-phase hybrid inverter

The ei-tre hybrid inverter is the three-phase model, specifically designed for the tertiary and small industrial sectors, capable of managing up to 23kW with energy production and consumption monitoring via App and Beghelli cloud, thanks to the integrated Wi-Fi module. Alternating current output for use of the energy supply in the event of a mains blackout.
