" Design, efficient and long living "

Maximum efficiency and longevity

The high efficiency of the inverters results in a peak efficiency rate of 98.6% and a European efficiency rate of 98.2%, which leads to a decrease in power dissipation and a reduction in heat in the environment. These figures summarize your performance benefits. In addition, a unique new cooling concept ensures uniform heat distribution in the interior and thus a maximum longevity of the appliances.

Design and visualization

The StecaGrid UPS has an LCD graphic display which allows you to visualize the energy efficiency values, the current powers as well as the operating parameters of the installation. An innovative menu offers you the possibility to select the different measured values ​​according to your needs. A preset and pre-programmed menu allows you to complete the final commissioning of the device without any problems.


With a weight of only 9 kg / 9.5 kg, the wall mounting of the inverters is both safe and easy. The supplied wall brackets and practical handles, suitable for both right and left-handed users, also contribute to high mounting comfort. It is also not necessary to open the device during installation. All fittings and the DC disconnect switch are accessible from the outside.
