Inverter StecaGrid 500

The StecaGrid 500 inverters were developed to make the use of solar energy as simple as possible. They are simple to install, easy to expand, and can be optimally adjusted to suit the local irradiation conditions.

The StecaGrid 500 is perfectly suited to smaller solar systems between 300 W and 3,600 W. The StecaGrid MiniString inverter series comprises the StecaGrid 500 inverters. The devices are rated at 500 W, but can be expanded and combined with each other. Together, they form a system composed of two or more module strings (referred to as multi-string system). System sizes of 300 W to 3,600 W are possible. StecaGrid MiniString inverters have an independent MPP tracker and achieve a very high efficiency of up to 95.8 %. The modularity of the system makes the inverters suitable for smaller systems and/or systems on partially shadowed roofs.
