Grid-tie solar inverter Refusol 20К

The three-phase inverters with power from 8.25 kW to 20 kW are ideal for photovoltaic systems for power of 8 kW and above. They meet all the requirements of protection IP65 - their housing provides protection against dust and water, including high-pressure washing. These systems can be installed in the open air without any problems. All inverters of this line are easy to use and compact. For example, they can be installed on an area of ​​less than three A4 pages, folded unlikely. Monitoring and control of inverters is carried out easily, it also contributes to the graphic display, built-in interface RS485 and Ethernet-connection.
Rapid detection MPP and a wide input voltage range provides a high level of efficiency. Even at a low three-phase inverters irradiation efficiency to reach 98.2%. As a result of this high level
convection cooling efficiency - that is all that is necessary for dissipating heat. Due to the low voltage level with respect to ground oscillations transformerless devices can also be used for a large number of thin-film modules.
Integrated Remote access system can send all the important information via Internet portal REFU directly to the user. For visualization and offers improved data can be transferred via a conventional cable or a wireless connection via radio module REFU. The processed information as of the processes of production and productivity is available at any time
