REFUsol 100K The next generation of solar string inverters SUITABLE FOR REPOWERING APPLICATIONS High design flexibility Best serviceability Maximum power density Minimized BOS costs With maximum power density, REFU’s next generation inverter family combines compatibility, installation flexibility, serviceability, and connectivity in a revolutionary design. Compatibility: This inverter can be connected to any grid voltage between 200 and 480 VAC, offering maximum power between 48 and 100 kVA. Installation Flexibility: The inverter can be mounted in a vertical or horizontal position as demanded on site. The roomy ConnectionBox is available with either fused direct string connections for decentralized designs, or with single DC input for centralized designs. Serviceability: The PowerUnit can be quickly detached from the ConnectionBox for trouble-shooting and measurements without disconnecting the power cables on the DC or AC side. Connectivity: The inverter can be commissioned via the REFUset app (available for iOS and Android) which connects seamlessly via Bluetooth® to the inverter. The integrated, fail-safe Ethernet daisy chain (alternatively RS485) allows cost efficient high-speed monitoring without special accessories. Each inverter can be individually connected to the REFUlog portal for remote monitoring, configuration, and updates. MADE IN
