Setting new benchmarks with sustainable solutions - that’s the philosophy of the pioneer of the frequency converters. REFU Elektronik pursues it with every offered product, whether in solar, storage or hybrid applications. Our company, founded in 1965, profits from its long experience and large expertise in power electronics when providing innovative high-quality inverters and battery storage systems.
With their low voltage ranges, the REFUone single-phase string inverters in the performance classes 3 to 7.5kW are particularly suitable for small systems. They comply with all requirements for IP 65 protection – their housing provides reliable protection from dust and water and therefore allows installation in the open without any problem.
The string inverters are easy to handle and compact, the detachable rust-free aluminum covers as well as the Plug&Play connections allow an easy installation. Operation and monitoring are easy, further facilitated by the graphic display, the integrated RS485 interface and optional WiFi/GPRS connection.
The REFUone inverters achieve an efficiency of up to 98% even at low irradiation. The independent dual MPPT tracking is highly precise with an efficiency of more than 99.9%. It allows better adaptation to different roof designs.
The inverters allow and intelligent grid management through reactive power capability and the possibility to limit power output as either zero or adjustable power limit export.
