REFU launches new 100kW string inverter at WFES in Abu Dhabi

  News

Pfullingen – As a prelude to an exciting 2018, REFU will launch its entirely new 100kW string inverter at the 2018 World Future Energy Summit (WFES) in Abu Dhabi (January 15th-19th) You will find REFU as part of the German Pavilion, booth number 7134.


The new REFUsol 100K is the logical continuation of the proven REFUsol 8-23K and REFUsol 40/46 K string inverter ranges. It can be connected to any grid voltage between 380 and 480 VAC offering maximum power between 83 and 100 kVA. The device underlines REFU remaining true to its global approach offering maximum compatibility, flexible installation and easy serviceability.

The REFUsol 100K consists of two parts – the power unit and the ConnectionBox offering flexible installation options. The ConnectionBox can be mounted in a vertical or horizontal position as required by the site conditions. It is available in two variants - with either fused direct string connections for distributed designs, or for a centralized designs with a single DC input. Thanks to the bisection of the device, the ConnectionBox can be installed and connected on site, while the power unit can be added shortly before commissioning to optimize your investment. If necessary it can be quickly detached from the ConnectionBox for trouble shooting and measurements.

The REFUsol 100K inverter is commissioned easily via app (available for iOS and Android) which connects seamlessly with Bluetooth® to the inverter. The integrated, fail-safe Ethernet daisy chain (alternatively RS485) allows cost efficient high-speed monitoring without special accessories. Each inverter is individually connected to REFUlog for professional monitoring, configuration and remote firmware updates.

“The new 100kW inverter continues our rich tradition of technology leadership and innovation. It underlines our aspiration to develop the right solutions for our customer’s demands combining maximum performance, simplicity and flexibility.” states Ralf Betkerowitz, CEO of REFU Elektronik GmbH.

Zouhair Kefi, Senior Vice President Segment Solar, Energy and Hybrid at REFU, adds: “We are excited to launch the next generation of our string inverter range, and this is not yet the end.  We might have been too early for the solar market when launching the industry’s first 1,500 V as early as 2011, but we build on this knowledge and experiences for our new REFUsol 125kW/1,500V inverter that will round off our portfolio by the end of the year.”
