Tell us what died — a photo of the old unit's label is perfect. We confirm the right replacement model, check your battery compatibility, tell you whether G98 or G99 applies, and book the swap. One fixed price, in writing, before anything happens.
Free remote diagnostic firstBattery optionsWhat an amazing service. They got my solar inverter back up and running after a firmware update went wrong. It is a breath of fresh air to deal with such a professional company.

Great communication from start to finish No question unanswered and very knowledgeable

Brilliant. He fitted a new dongle and set the system up properly. Even better, he explained why the storage batteries don't work in a power cut - not correctly wired up - expensive to fix, but a simple turn of the master switch will give emergency power. He is the third technician to look at this issue and the only one to resolve it. Friendly and appoachable, comes when he says he will and reasonable charges. What's not to like!

Ron diagnosed the problem remotely - efficiently and order the part identified as the fault - this part came directly from to me and Ron visited within a few days and within the hour corrected the problem and since everything has been excellent -highly recommended - very pleasant manner and lovely to work with .

I can’t praise this firm enough. After hearing my solar panels rattling in very windy conditions, I contacted Solar Tech (as my installers no longer trade). Ronald was fantastic at explaining what he thought the issue was likely to be. Communication was great throughout keeping me fully updated. The team worked really hard on the day to carry out the necessary work. I can now sleep soundly at night without worrying about the solar panels on my roof. I would thoroughly recommend this firm. Thank you for sorting the problem out.

GivEnergy replacements, one fixed price
This page covers replacement GivEnergy inverters supplied and installed by STS. We don't recommend GivEnergy for new systems. We still support and supply parts for existing ones. If a different brand died, see the general inverter replacement service. And before you buy anything: a fair share of "dead" inverters are a settings or firmware fault — the remote diagnostic is free, no fix, no fee.
Supplied & installed
The range
Three replacements, three fixed prices
New units, available now. Every price covers the inverter, removal of the old unit, installation, commissioning, and portal configuration — nothing quoted separately afterwards.
3kW AC-coupled
£847 supplied & installed
→Replaces an existing GivEnergy AC-coupled unit
→Keeps your existing solar inverter in place
→Warranty included — full terms provided in writing with your quote.
The battery-side box: it manages charge and discharge, your solar inverter keeps doing the solar.
3.6kW Gen 3 hybrid
£1,191 supplied & installed
→The straight swap for a dead Gen 1/2 hybrid — existing LV GivBat batteries carry over
→G98-certified: at ≤3.68kW per phase it is notify-after-connection — the fastest route
→Warranty included — full terms provided in writing with your quote.
The right pick for most arrays around 4kWp and under — no DNO approval wait.
5kW Gen 3 hybrid
£1,191 supplied & installed
→Same installed price as the 3.6kW — choose by array size and DNO headroom
→Usually needs a G99 application (prior DNO approval) — we handle the paperwork with our DNO support service (£95)
→Warranty included — full terms provided in writing with your quote.
For bigger arrays, or headroom to expand — worth the G99 process.
Every price above includes the inverter, removal of the old unit, installation by our engineers, commissioning, and portal configuration so your monitoring carries on. One price, nothing added later.

🩺
The inverter might be repairable. Firmware, settings and comms faults regularly masquerade as dead hardware — and the rapid-clicking fault has its own specific causes. Start with the free remote diagnostic, and read inverter not turning on or the clicking fault first if the symptoms match.
Choosing
Which model
AC-coupled or hybrid — and 3.6 or 5?
Two decisions, both simple once you know what the old unit was doing.
AC-coupled vs hybrid
A hybrid takes the solar DC directly and manages the battery — one box does everything, so a dead hybrid gets replaced by a hybrid. The AC-coupled unit sits alongside a separate solar inverter and only manages the battery — it is the replacement when that box dies. Not sure which you have? Send a photo of the label — we identify it the same day.
3.6kW vs 5kW — the DNO angle
Same price, different paperwork. The 3.6kW is G98: install first, notify the DNO within 28 days — fastest possible swap. The 5kW is G99: the DNO has to approve it before installation, which can add weeks. Our DNO application support (£95) handles the forms either way. G98 vs G99 explained →
Replacement GivEnergy inverters — common questions
Check what the dead unit is. If it is a GivEnergy hybrid (solar DC comes into the inverter and it manages the battery), the like-for-like swap is a Gen 3 hybrid — 3.6kW or 5kW to match your array and DNO position. If it is the AC-coupled unit (it sits alongside a separate solar inverter and only manages the battery), the 3kW AC-coupled is the direct replacement. Send us a photo of the old unit's label with your enquiry and we will confirm the right model before anything is booked.
Yes. One fixed price per model, supplied and installed: it covers the inverter itself, removal of the old unit, installation and wiring by our engineers, commissioning, and portal configuration so your monitoring carries on working. No call-out fee, no separate labour line, no parts added later. The only thing ever quoted separately is DNO paperwork support if your model needs a G99 application — that is £95 through our DNO support service, and we tell you up front if it applies.
Same installed price — £1,191 — so choose by array size and DNO headroom, not cost. The 3.6kW Gen 3 is G98-certified: at or under 3.68kW per phase it only needs a notification after connection, which keeps the swap simple and fast. The 5kW Gen 3 is G99 territory: it usually needs prior approval from your DNO before installation, which adds paperwork and lead time. If your solar array is around 4kWp or less and you want the quickest route, the 3.6kW usually wins; if you have a bigger array or plan to expand, the 5kW is worth the G99 process. G98 vs G99 explained →
In most cases, yes — a dead Gen 1/2 hybrid to a Gen 3 hybrid is straight-swap territory. The Gen 3 3.6kW and 5kW hybrids run the same 51.2V LV GivBat battery range, so existing LV batteries carry over; in a mixed-generation stack the Gen 3 side takes the Master role, and we sort the addressing and cabling as part of the install. The portal configuration is redone so your history and monitoring continue. We confirm compatibility from your battery model before booking — that is part of the free check, not an extra.
Genuinely, sometimes — and it costs nothing to find out. A fair share of "dead" GivEnergy inverters are a firmware, settings or communication fault rather than failed hardware, and some fault patterns (like the rapid relay clicking) have specific causes worth diagnosing before any money changes hands. Start with the free remote diagnostic — no fix, no fee. If the unit really is done, you already know the fixed replacement price. Inverter not turning on →
The physical swap is usually a half-day on site — old unit off the wall, new one mounted, wired, commissioned, and the portal reconfigured before we leave. The variable is the DNO side: the 3.6kW (G98) can go in straight away with a notification afterwards, while the 5kW (G99) usually needs the DNO's approval first, which is DNO-specific and can take a few weeks. We book the install around that timeline and handle the paperwork with you.
