The new generation of REFUsol 08…23K three-phase sting inverters is based on the successful platform which delivers maximum yields with no maintenance. The new software allows easy future addition of accumulators, integration of PV systems in smart grids or adaption to regulation changes. Decentralized PV projects can be planned and built flexibly, as the simple layout can be rapidly multiplied. Partial systems connected to the grid during the construction phase provide early yields.
Performance and reliability are what counts in large PV systems. The new REFUsol 40/46K inverters offer both. They are passively cooled without external fans and therefore require nearly no maintenance resulting in a long lifetime. The proven Ultra-Eta topology allows even with partial loads an efficiency over 98 %, which speeds up the return of investment. Thanks to the external DC connection box the inverters can be positioned close to the strings or combined at one point within the plant.
The REFUhybrid 100 is a 96.6 kVA/400 VAC battery inverter/charger designed for commercial & industrial storage applications. The inverter is scalable up to megawatt range through parallel connection of several units. Its transformerless design results in lower weight and therefore reduces shipping costs and allows a faster installation. Exemplary applications among others include the provision of grid services, fuel saving in PV-diesel microgrids and integration of PV powerplants.
