High-efficiency solar inverters - Made in India
REFUsol opens inverter production in Pune

Pune/India,Tuesday, March 19, 2013 - REFUsol, a leading manufacturer of solar inverters has started producing its high efficiency solar inverters in a local production in Pune, India. The first inverters were produced in February 2013. REFUsol will manufacture its 10kW, 13kW ,17kW, 20kW and 23kW string inverters for the Indian, South Asian and Middle East market.

The three-phase string inverters REFUsol 010K, 013K, 017K and 020K are suitable for rooftop systems from 10 kW upwards, right through to megawatt parks. They comply with all requirements for IP65 protection and their housing provides reliable protection from dust and water, including high pressure washing. Therefore, these systems can be installed out in the open without any problem. All four string inverters are easy to handle and compact. They can be installed on an area smaller than three A4 pages laid side by side for example. Operation and monitoring are easy, further facilitated by the graphic display, the integrated RS485 interface and an Ethernet connection. Fast MPP tracking and a wide input voltage range also ensure the high levels of efficiency that are typical in REFUsol systems.

Even at low irradiation, the three-phase inverters achieve an efficiency of up to 98.2 per cent. As a result of these high efficiency levels, convection cooling is all that is needed to dissipate the heat. Thanks to the low voltage fluctuations against earth, the transformer-less devices can also be used for many thin-film modules. The integrated data-logger can send all important operating data to the REFUlog internet portal. For visualization and evaluation purposes, data can be transferred via the standard cable or an optional wireless connection using the new REFUconnect radio module.

With an output voltage of 460 volts and an input voltage range of 575 to 850 volts, the REFUsol 023K-460 VAC is the ideal solution for medium-voltage applications on large-scale PV sites. It has an efficiency factor of more than 98 per cent. The high efficiency enables noise-free convection cooling and ensures the inner workings of the inverter are maintenance-free.

"EPCs and investors like the concept of our high efficiency inverters which is not only giving them capital cost benefits but also help them to reduce the operational cost of plant and getting 2 to 3% more generation benefits. With our local production here in Pune we are now able to meet our customer's needs even better and in shorter time" confirms Thomas Wittek, CEO at Refu Solar Electronics Pvt. Ltd.
