What information do you need to quote for a solar inverter repair?

The extra details that make a solar inverter repair quote more useful are the installation history, monitoring information, system layout and access arrangements. They help us judge whether the likely work involves a replaceable component, further testing or a site visit before we can give a firm price.

Installation and warranty records

• Tell us when the solar system was installed and who installed it, if you know.
• Send the installation certificate, electrical test certificate or commissioning record if you have them.
• Include any warranty information, service history or previous repair reports.
• Let us know about recent electrical work, a power cut, storm damage, roof work or changes to the battery system. These events can point to the cause of an inverter fault.

These records can also show how the panels, inverter, battery and export equipment were connected originally. That matters when a replacement part needs to match the existing system.

Monitoring and performance information

If the system has an online monitoring app, send screenshots of its event log, daily generation graph and any communication warnings. A screenshot showing the date and time of the latest error can be more useful than a general description of the problem.

Tell us if the monitoring stopped at the same time as the inverter fault, or if the app continued to show data. That distinction can help separate an inverter problem from a communications or internet connection issue.

System arrangement

Let us know whether the battery is connected directly to the inverter or has its own inverter. If you have a backup supply, immersion diverter or other energy equipment connected to the system, include that information too.

A photo of the consumer unit, generation meter and any clearly labelled solar isolators can help us understand the electrical arrangement. Do not remove covers to take photographs. We only need equipment that you can see safely without touching the installation.

Property and access details

Give us the property address and explain where the inverter is mounted. A garage, utility room, loft, outbuilding or external wall can each affect how we inspect and test it.

Tell us if furniture, stored items, locked gates or other obstructions restrict access to the inverter or its isolators. If the equipment is high up or difficult to reach, mention that before we arrange an inspection. We can then plan the visit properly rather than discovering an access problem on arrival.

What you want the quotation to cover

• Say whether you want a repair only, a replacement inverter or an assessment of the wider solar system.
• Tell us if the battery, panels or export supply also need checking.
• Explain any preference for retaining the existing monitoring system or changing the equipment.
• Let us know if the system is needed for a particular property transaction, insurance claim or planned electrical work.

We can use this information to prepare a more relevant quotation, but a remote assessment cannot identify every fault. If the evidence does not show whether the problem is inside the inverter, in the DC cabling, at an isolator or elsewhere in the installation, we may need to test the system on site before confirming the repair cost.

Send clear images at full resolution, along with the relevant certificates and monitoring screenshots. Remove account passwords and other personal login details. Never open the inverter or reset equipment repeatedly just to gather more information.
