The REFUsol 48K-UL is equipped with the proven Ultra-Eta topology. Even with partial loads the efficiency is over 98%, which speeds up the return of investment.
Thanks to the external DC connection box you can plan and build your decentralized PV project flexibly. Whether you position the inverters close to the strings or combine them at one point within the plant is a decision that only depends on your plant design, not on the inverter.
