The system already installed in our house was not working, and since I didn't know any installers to ask for help I contacted Zontech. Without hesitation Arjan provided helpful advice - truly excellent service. We will be back when it's time for a battery.

The installation of the SolarEdge backup battery was completed professionally and within a day by ZonTech Nederland bv. We are very satisfied with the explanation and installation of the emergency power system.

After 11 years, our inverter broke. No problems with the panels or inverter for 11 years! Due to unforeseen circumstances, we urgently needed a new one. After a quick call, they found one in stock and could install it the next day. Excellent service!

I had 12 panels and a home battery installed through Zontech. They work with top brands, ensuring you get a quality product. The installation went very smoothly, and their team goes above and beyond. Moving a 120kg home battery to the fourth floor and then mounting it higher than 1m on the wall was no problem (though it was a challenge ;-)). The installation was very professional and neat, all in a single day. They were able to answer all technical questions immediately, so you know they really know their stuff. The experience exceeded my expectations. I'm happy with it :-)
