FAQ

Frequently asked questions

Does GNS carry out all work in-house?

Yes. Consultation, planning and installation are done exclusively by our own team at our workshops in Mönchengladbach and Bruckberg.

Can I combine several services in one appointment?

Absolutely – most customers combine solar, lithium and an inverter into one off-grid package, saving time and installation costs.

Will you install components I bought myself?

Ask us: after a technical check we can install customer-supplied brand components in many cases.

Ready for true independence on the road?

Call us or send an enquiry – we usually reply within one working day.
