Repair instead of throwing away!

We know a thing or two about photovoltaic inverters, too

Thanks to our over 30 years of experience in repairing and servicing CNCPLC and ROBOT automation systems, we’ve been able to provide comprehensive support for inverter technology to many manufacturers.

And now – BVS goes green!

We now also offer our services for photovoltaic inverters from different reputable manufacturers. Due to the similarity in structure of the modules from different inverter providers, we’re able to comprehensively offer you a complete product overhaul repair at an estimated price as well as cleaning and inspection for all types of inverters.

Whether you use modulestring or central inverters, whether they are current models or ones that have already been discontinued by the manufacturer – we have what you need!
