Our experience defines us.
We have been developing and selling solar inverters for over twenty years and have more than 250,000 inverters installed worldwide. The REFUsol inverters stand for innovation, quality and reliability. Our portfolio of string inverters offer maximum simplicity and flexibility in all project phases. Whether centralized or decentralized systems we have a solution for you and offer you support right from design through planning, commissioning and even during operation. We and our string inverters offer simple advantages such as string level monitoring during operation, maintenance free service and simple replacements in case of failures.
String inverter REFUsol 100K
Maximized in every aspect
- Highly flexible design
- Maximum power density
- Best serviceability
- Minimized BOS costs
With maximum power density, REFU’s next generation inverter family combines compatibility, installation flexibility, serviceability and connectivity in a revolutionary design.
Use as desired, maximum ROI
Regardless of whether you plan the inverters in centralized or decentralized fashion, the REFUsol 100K is optimized for both variants. The roomy ConnectionBox is available with either fused direct string connections for decentralized designs or with a single DC input for centralized designs.
The ConnectionBox and the PowerUnit can be delivered independently of each other in separate shipments. The ConnectionBox is first installed and wired, while the PowerUnit is added shortly before commissioning. This optimizes your finances since the investment can be distributed and minimizes risks.
Global use, full control
The REFUsol 100K can be connected to any mains voltage between 380 and 460 VAC and offers maximum power between 83 and 100 kVA. All technical data for the different AC output voltages can be found in our technical data sheet.
The inverter can be commissioned via various means including our new REFU App (available for iOS and Android), which connects to the inverter via Bluetooth®. The integrated, fail-safe Ethernet daisy chain (alternatively RS485) enables cost-effective high-speed monitoring without special accessories. Each inverter can be connected to REFUlog for professional remote monitoring, configuration and firmware updates.
