PV service and troubleshooting – including systems installed by other companies

Is your system producing too little power, showing an error or missing from the monitoring portal? We find the cause – whether the problem is the inverter, data logger, cabling, network or settings – and make sure it gets fixed.

Our focus

Is your system producing too little – or has it gone silent?

Often the modules aren’t the problem. Usually the fault lies in the data connection, the cabling or the settings: a new router, a new Wi-Fi password, a mobile network that has been switched off. We track down the fault step by step instead of replacing parts on suspicion – even on systems installed by others.

Connection problems we solve

  • Monitoring offline – the system no longer appears in the portal and no yield data comes in
  • Data loggers & communication modules – troubleshooting, repair, set-up
  • Internet connection – Wi-Fi, network cable, mobile network, new router
  • Interfaces – so that inverter, storage, meter and energy management talk to each other
  • Remote access & portals – restoring access, re-registering the system in the manufacturer’s portal

Service for the whole system

Not every fault is down to the data connection. We look after the whole system – so you have one contact, wherever the fault is.

  • Troubleshooting for error messages, shutdowns and low yield
  • Replacing faulty communication parts such as data loggers or communication modules
  • After hail or storms: inspection and report for your insurer
  • Written service report after every visit

FAQ

Frequently asked questions

Do you also service systems installed by another company?

Yes, that’s a large part of our work. Many installers no longer exist or no longer come out. Helpful are the system documents, the portal login details, a photo of the inverter type plate and the latest error message. If anything is missing, we’ll find out on site.

My monitoring shows nothing – is the system broken?

Not necessarily. Often the system keeps running and only the data connection is lost – for example because of a new router, a new Wi-Fi password, a mobile network that has been switched off or a faulty data logger. Check whether the inverter display shows power output and send us a photo. Then we can usually narrow down the fault in advance.

How much does a service call cost?

That depends on the system and the fault. Get in touch and send us a few photos of the entire system in advance. This gives us a first impression and lets us estimate the costs more accurately. For larger jobs you receive a written quote beforehand.

Do you also offer new PV systems?

Yes. We plan new PV systems for homes, businesses and farms to match your consumption, not just your roof area – with battery storage, backup power and a wallbox if you wish. Installation is handled by our partner company for electrical work. Afterwards, we remain your point of contact for any faults. We look after existing systems just the same – even if another company built them.
