Book consultationFree remote diagnosticRon was extremely helpful and tried his best to repair/reset our GivEnergy inverter remotely. In the event he was unsuccessful but he couldn’t have been more helpful. If you have problems with a GivEnergy system please contact him. Highly recommended
What an Amazing service and so helpful . I have had problems with a faulty GivEnergy inverter and Ron has been so diligent in investigating and reporting on it . I’d give him more than 5 stars if I could for his help in diagnosis and potential solution. Thoroughly recommend .
Wow... a firmware update to my inverter sent the whole system into meltdown – the battery discharged, and the house seemed to be drawing power, and the solar, who knows where that was going? Aghhh... A short email exchange with Roland and Solar Tech Support sorted the problem... the firmware had reversed a setting (from when it was installed), and the CT clamp needed to be reversed. As soon as I had done that, the world returned to normal. Thanks, Roland; there is no way I would have come to that conclusion. Would I recommend them? You bet! Worth the fee? You bet, again!
Ron took me through a diagnostic to confirm my GivEnergy Inverter had a fault. A common one as it turns out with the AC Inverter. As GivEnergy is defunct there is no immediate fix, aside from sourcing 2nd hand replacement. It may be that a fix becomes available over the summer which would make a lot of GivEnergy customers happy (Again)
Great service. Got our Givenergy battery back online remotely when others said it needed an onsite visit. Ron resolved the issue within about an hour of my email. Brilliant service.
Newport is full of FiT-era solar with no battery — and we're 20 minutes away
South Wales took up the Feed-in Tariff in big numbers between 2011 and 2016, and most of those Newport systems are still solar-only a decade later. They generate happily through the day, export the surplus for pennies, then buy it back at a much higher rate every evening. A battery closes that gap. We cover Newport from our Cardiff base — about 12 miles east, a 20-minute run on the M4 — so it's one of the quickest places we reach, with next-day surveys and no travel surcharge. We start with a free remote diagnostic the same day you get in touch.
FiT-boom era when most Newport solar was fitted — solar-only, ready for a battery retrofit now
Newport sits ~12 miles east of our Cardiff base on the M4 — free same-day remote diagnostic, next-day on-site survey
Our most-installed retrofit battery in South Wales — pairs with any existing inverter brand
Some of those early Newport systems were fitted by installers that have since closed — Solar Plants of Port Talbot, just along the M4, was dissolved in 2022, and several other South Wales firms followed. If yours was one of them, the panels are almost certainly still generating but may never have been upgraded. Adding a battery is straightforward: we identify the existing hardware, recover monitoring access, verify FiT registration, and retrofit a GivEnergy battery in a single process. No original documentation needed.
How a GivEnergy battery retrofit works with your specific inverter
Every inverter brand integrates with storage a little differently. Here's what the retrofit looks like for the brands most common across Newport — with GivEnergy as the battery in almost every case.
GivEnergy is the dominant battery in Newport retrofits. If you already have a GivEnergy AIO or hybrid and want more capacity, we add a slave or expansion battery to your existing stack — no new inverter needed. If your GivEnergy system isn't performing as expected, we diagnose and reconfigure remotely before recommending any new hardware. GivEnergy support → · add an expansion battery →
SolarEdge systems use DC optimisers on each panel with a central inverter. AC-coupling a GivEnergy battery alongside SolarEdge is straightforward — the battery inverter connects to the consumer unit independently. SolarEdge's own StorEdge interface exists but needs a compatible SolarEdge inverter. For most Newport homes, an independent AC-coupled GivEnergy battery is cheaper and more flexible than the StorEdge route, and your panel-level optimisation continues unchanged.
Enphase converts DC to AC at each panel, so there's no central string inverter. That means DC coupling isn't an option — AC coupling is the only route, which is actually ideal. You add a GivEnergy battery inverter to the consumer unit, the CT clamp monitors total consumption, and the battery charges from surplus Enphase output. Enphase's own IQ battery exists but costs significantly more than a third-party AC-coupled alternative. We install both — your choice.
The most straightforward retrofit. Fronius IG, Primo, and Solis string inverters are simple solar-only units — AC-coupling a GivEnergy battery alongside them needs no changes to the existing system at all. If the Fronius or Solis is approaching end of life (10+ years), consider combining the inverter replacement with a DC-coupled battery in one visit — saves a second installation and often works out cheaper than two separate jobs.
AC or DC coupling? The right answer depends on your inverter
For most Newport systems — the solar-only FiT-era arrays on terraces across Maindee, Pillgwenlly and Stow Hill — AC coupling is the better option. DC coupling makes sense when an older inverter is already failing and due for replacement anyway.
Newport-specific recommendation: If you have a SolarEdge or Enphase system, AC coupling is the only practical route — and a GivEnergy battery does the job perfectly. If you have a healthy Fronius or Solis, AC coupling is cheaper. If that Fronius or Solis is showing its age, DC coupling lets you swap the inverter and add a battery in one go. A free remote diagnostic tells you exactly where you stand — same day. Full technical comparison →
Battery systems we install across Newport
Newport's housing runs from tight Victorian and Edwardian terraces in Maindee and Pillgwenlly to larger semis in Allt-yr-yn, Caerleon and St Julians. A 4.8 kWh GivEnergy AIO suits a 2–3 kW terrace; a larger stack makes sense for a bigger system running Octopus Flux. We recommend on your system, usage and space — not on commission.
The most popular battery retrofit in Newport by a wide margin. 4.8 kWh or 9.5 kWh in a single wall-mounted unit. Pairs with any existing inverter brand and expands with extra battery modules later. Optional EPS backup available. GivEnergy support →
Modular battery stack that scales from around 5 kWh upward. A strong choice for larger Newport properties with bigger systems and high evening consumption. Works in both AC and DC coupling, with reliable firmware and a clean monitoring interface.
Compact and quiet — fits well in the under-stairs cupboards and small utility spaces common in Newport's older terraced housing around Maindee and Stow Hill. Solid app-based monitoring, and good value in the smaller-capacity range.
All offer AC and DC coupling with built-in EPS capability. Popular on full new-build installs across Newport and the surrounding Gwent levels. Brand choice often comes down to monitoring-platform preference and consumer-unit layout. We install and commission all three.

Battery retrofit pricing in Newport
A GivEnergy AIO added to a solar-only system — ideal for Newport's compact 2–3 kW FiT-era arrays. Captures the daily surplus on a terraced property and covers evening use through to bedtime. Capacity confirmed in your quote.
Already running a GivEnergy AIO or hybrid? Add a slave or larger expansion battery to your existing stack — no new inverter needed. Best for larger Newport homes on time-of-use tariffs wanting more overnight capacity.
Hybrid inverter plus battery in one package — the hybrid inverter is quoted separately by capacity. The smart move if your Fronius or Solis is already failing — combine the inverter replacement with the battery in a single visit.
Every quote includes hardware, installation, CT clamp, commissioning, DNO G99 variation, and a written post-installation report. Newport is ~12 miles east of our Cardiff base on the M4 — no travel surcharge, and one of the quickest places we schedule. Guide to adding an extra battery later →
Newport installer closed down? Add a battery and we'll recover the whole system
Plenty of South Wales solar firms from the FiT boom have since dissolved — Solar Plants of Port Talbot, just along the M4, entered administration in 2020 and was dissolved in 2022, and others followed. If your installer is gone, your panels are almost certainly still generating, but you may have no monitoring, no documentation, and no one to call. We combine a battery retrofit with full system recovery in a single engagement: identify the hardware, recover monitoring, verify warranties, fit a GivEnergy battery, and leave you with a fully documented, actively managed system.
For former Solar Plants customers across South Wales — monitoring recovery, warranty claims, ongoing support.
