Interactive repair and maintenance enquiry form

Welcome to our online interactive fault diagnosis tool. Complete the fields below as fully as possible and this interactive tool may provide an instant diagnosis. The more information you provide, the more effective it is and it also prompts you for the information we will need to assist you. If you don't know any answers for sure, please don't guess!
Please be aware that we are based in Lancashire. As you are not close by we will not be able to offer you any on-site services. However, if you have a fault then completing the questions may steer you toward the cause of your issue and in the case of a faulty inverter or other component we may be able to guide you through a DIY repair or replacement.
Please select an option. If not known then please choose 'Unknown'. If not listed please choose 'Other'
Your inverter model number and serial number can usually be found on a label on the side or underside of your inverter.
Why do we ask this? Certain companies made consistently the same mistakes/short cuts with their installations and this often gives us a clue as to what might be wrong.
If it's around 5 years, is it over or under? This is important as most inverter warranties are 5 years.
A picture speaks a thousand words! If you have any photos or other documents that can help us understand your installation then please upload them here. Particularly useful are photos of the inverter model number sticker, the connections into the inverter and an overall picture of the inverter area showing all isolators etc. You can also email us at
