18.07.2022 - Soon available at EWS: Inverters from Solis and KACO

In times of limited availability and strained supply chains, we are expanding our inverter portfolio by two additional suppliers, which puts us in a position to be able to immediately present you with freed up delivery capacities from our wide product range. In our online purchasing advisor QuickShop, you will now also find the attractive product series from KACO new energy and Solis, which are scheduled to arrive in the warehouse at EWS as early as August and October 2022 respectively. The traditional Swabian company KACO new energy is a Siemens subsidiary with a great deal of experience and Solis is one of the largest inverter suppliers worldwide with particularly economical solutions in all performance classes.


With products from the manufacturer Ginlong Technologies, better known under the brand name Solis, we are expanding our range of inverters. The company from Ningbo in China has been developing and producing solutions for all areas of application since 2005 - from small private systems to commercial PV systems. And it has been extremely successful: In the past year, Solis ranked third among inverter manufacturers worldwide in terms of total deliveries.

Versatile, reliable, attractive prices

RHI-3P(5-10)K-HVES-5GIn the area of single-phase and three-phase string inverters, Solis has all performance classes covered - at EWS you can get models from 2.5 to 110 kW.

The cloud monitoring platform SolisCloud with many features enables intelligent monitoring of the PV system.
