Both in the lower power class (the "string inverters"), as in the "central inverters", as in the backup and offgridtoepassingen, SMA has an extremely sterkg range. SMA inverters attach the highest efficiencies in the market for reliability and functionality. In addition, their own service department in Mechelen guarantee a worry-free after-sales service.

This state-of-the-art SMA inverters, made in Niestetal, Germany, make their expectations more than true. With unprecedented maximum efficiency (up 98.1%) and excellent MPP these inverters will give you the best performance possible. SMA stands for everything you need to make an investment: efficient, reliable, safe and simple. With over 5500 employees and a turnover of € 1.5 billion (2012) the organization has a leading global position in key PV markets.


The Sun2000 inverters Huawei are well tested by Photon. Both average and high irradiation they get the highest score. The inverters are very competitively priced. The company is a leading provider of ICT solutions in more than 140 countries. Third of the world communicates using equipment from Huawei. The inverters are based on 20 years of experience in power supply.

The portfolio consists of three phase inverters 8-23 kW. For larger capacities Huawei provides medium voltage inverters. The inverters have two Trackers (8kW, 12kW). The higher powers have even three MPP trackers.

Due to a high protection class Huawei inverters can be used outdoors.

The Sun2000 inverters comply with the German BDEW MV directive VDE AR ​​N 4105 LV Directive. They also comply with the CE Low Voltage Directive and the Electromagnetic Compatibility Directive. Also, they have the Italian Enel-GUIDA- and CEI 0-21 certification. As well as the Chinese Golden Sun certification.

Obviously, a comprehensive monitoring via Ethernet platform available.
