Hybrid inverter upgrade

A hybrid inverter does the same job as an ordinary string inverter and can also manage a battery, which makes replacing a failing or ageing inverter the natural point at which to think about storage.

Under the 2026 REWS scheme, replacing the inverter on a PV system more than six years old, together with a battery, attracted 75% of the cost up to €1,800 and €350 per kWp — a figure we have from an installer's summary rather than the guidelines, so treat it as indicative. The scheme closed on 12 September 2026; a further round was announced but not detailed.

What this covers

• Diagnosis of the existing inverter and system
• A hybrid inverter matched to the array and any planned battery
• Removal of the old unit and installation of the new one
• Recommissioning, monitoring set-up and a check of the feed-in meter

Adding a battery at the same time?

A new hybrid inverter is the natural moment to decide on storage. StoreYourSolar explains when a battery pays in Malta, and the battery calculator works it out for your system.

What it costs

Inverter prices depend on the size of the array and whether a battery is going in now or later. There is no published Maltese figure, so it is quoted after the survey.

None of these has a published Maltese installed price we can stand behind, so each is quoted after the roof survey, itemised, before anything is ordered.

How it works

You deal with us, not with the installer. We survey the roof, quote a fixed price, bring in a solar installer from the CheckYourTraders-verified network, and stand behind the work. One point of contact, one contract, one invoice.

Questions people ask

My inverter shows a fault. Do I need a new one?

Not always. A health check finds out whether it is the inverter, the wiring or the grid side. If the inverter is failing on an older system, a hybrid replacement keeps the option of a battery open.
