Solar inverter repair. Power restored.

We assess solar PV string inverters from a wide range of manufacturers, including domestic and three-phase commercial models. Send the brand, model number, symptoms and any fault codes so we can check suitability. A catalogue listing is a useful starting point; the condition of the unit and component availability determine whether a repair is practical.

Yes. We work with homeowners, installers, commercial solar operators, and operations and maintenance teams. A homeowner may need help with a single unit, while an O&M team may need support across several sites. Repairs are assessed through our laboratories in the UK, France or Germany, depending on your location; contact us to agree the appropriate arrangements.

Typical repair turnaround is 10–15 working days, depending on the fault, component availability and the work required; some repairs can be completed sooner. We confirm the expected timing after assessment. Specialist or obsolete parts and the agreed shipping arrangements can affect the overall time, and our team will explain any limitations before you approve the repair.

Yes, collection and return options can be discussed with our team, or you can arrange to send the inverter to us. Contact us before dispatch for the correct destination, repair reference and packaging instructions. We will confirm the available service, shipping arrangements and costs for your location, including enquiries from France and Germany.

If repair is not feasible or economical, we can discuss replacement and procurement options. These can include new, refurbished and obsolete equipment where available. Model compatibility, condition, availability and warranty are confirmed before an option is agreed. We also offer free recycling for unusable units; contact the team to discuss the arrangements.

Include the manufacturer, full model number, any error message or code, a description of what has changed, your location and a contact number. Tell us whether this is a domestic system or a commercial site and whether you are an owner, installer or O&M provider. If you have photographs, mention them in the message so our team can advise how to share them.

It means diagnosing and repairing the individual electronic components responsible for a fault, where appropriate, instead of automatically replacing the complete inverter or board. The first step is a technical assessment: some faults can be repaired at component level, while other damage or unavailable parts may make replacement the better option.

We offer fixed repair pricing and confirm the price and agreed repair scope before work begins. Investigation charges are explained in advance; if the inverter cannot be repaired, you are charged for the investigation only. Collection or return arrangements and their costs are agreed separately. Any additional work outside the agreed scope requires your approval. Commercial customers can discuss their requirements with our team.

We carry out post-repair checks and testing to manufacturer specifications under operating conditions appropriate to the equipment and work performed before preparing the inverter for return. We can confirm completion and give a general fault summary, such as identifying an affected circuit board, along with any practical limitations of the agreed repair. Detailed component-level diagnostic reports and repair methods are not supplied, as these form part of ENS's proprietary technical know-how.

Repairs include a standard three-month warranty, with extended warranty options available. We confirm the applicable period, scope and terms with your quotation or supply documentation. If you need additional cover for a commercial operation, discuss your equipment and operational requirements with the team so we can explain the options.

Yes, enquiries about legacy and discontinued models are welcome. We first check repair suitability and the availability of components. If a repair cannot proceed, our procurement service can explore refurbished, obsolete or other replacement equipment. We confirm compatibility and availability for your application before an option is agreed.

Repair may extend the useful life of an inverter, avoid replacing sound components and reduce electronic waste. It can also offer a practical cost option, depending on the fault and parts required. We assess the equipment and explain the options so you can weigh up repair, replacement or recycling for your circumstances.
