The idea of eliminating waste was optimally implemented with the solar inverter series REFU sol of REFU sol GmbH. In order to waste as little of your money as possible, a new, highly efficient circuit topology achieves considerable efficiencies over a broad input voltage range: The REFUsol PV inverter family includes highly efficient string inverters from 04-20 kW, central inverters from 100 kW to 1.3 MW with integrated monitoring system REFU log ,as well as the temperature and irradiation sensor SI13TC-T-K .
+ DC disconnection point / insulation monitoring
+ Independent network separation according to VDE 0126
+ Ethernet, RS485 and temperature Sensor
+ BxHxT / Weight = 535x601x277 / 38,4kg
Founded in 1965 as Refu Elektronik, the company now operates as Refusol GmbH. The company, headquartered in Metzingen, Germany, is a specialist in power electronics and has specialized in quality inverters in general. Around 30 years after the founding of Refusol GmbH in 1979, the existing know-how was successfully transferred to the development of the first line-commutated inverter for the photovoltaic industry.
Today, Refusol GmbH develops, produces and distributes high-quality inverters, which with an efficiency of around 98.5 percent are among the most effective devices in the entire market. The company's string inverters and central inverters have an excellent reputation within the industry. Currently, Refusol GmbH covers every field of application with the available inverters and provides the right device for every photovoltaic system, regardless of its size. At the same time, Refusol GmbH operates its own internet portal Refulog. This serves to monitor and visualize all parameters of the respective photovoltaic system and offers numerous other functions.
Refusol GmbH has branch offices and subsidiaries in almost 20 countries around the world and has a good service and sales network. Thus, Refusol GmbH is represented in all promising markets of the photovoltaic industry, for example in Germany as well as in many other European countries, in China, India, Korea and the USA. Inverters from Refusol GmbH are generally characterized by a design that generally aims to keep the maintenance effort as low as possible.
Regardless, the Refusol GmbH operates a customer service, which offers the appropriate support very quickly and directly as well as personally present on site. Service and maintenance contracts of the Refusol GmbH additionally help to keep the running costs of a photovoltaic system as low as possible. The offered training courses and seminars of Refusol GmbH are mostly addressed to people who already have previous knowledge of photovoltaics. In particular, these are therefore employees of sales, architects, plant planners or fitters of photovoltaic systems.
Refusol GmbH offers a transformerless, single-phase string inverter for the small power range, while the three-phase inverter from Refusol GmbH is already designed for larger systems. The transformerless inverters of Refusol GmbH have extremely low voltage fluctuations to earth. This makes them ideal for use with thin film modules.
For photovoltaic systems on commercially used buildings or for free-field installations, Refusol GmbH offers corresponding large inverters. These are suitable for outdoor use. Their compact design and easy installation of the devices significantly reduce the construction costs of the entire system.
For larger systems, Refusol GmbH offers central inverters with their own protection against islanding. Also available are their own central inverter systems, which can be used due to their sophisticated design even in difficult environmental conditions.
