Add Battery to Existing Solar in Wakefield
The Wakefield district has thousands of solar systems installed under government energy schemes — most still generating but sending surplus energy straight to the grid for a fraction of what you pay to buy it back. Adding battery storage captures that surplus for evening use. Whether you have the original Fronius or Solis inverter or a newer GivEnergy retrofit, we survey, recommend, install, and commission — all with DNO paperwork handled.

Ron made more sense in 20 mins than our installer has done over the last 12 months There is a jungle out there and you need someone like Ron to give a comprehensive overview and solution

Massively massively recommended. We had a big battery array (49kW across three phases) put in four years ago. c £35k cost. It’s been a total nightmare for many reasons, not least 1. our installer being totally useless and unresponsive and 2. Givenergy, our battery supplier, going bust. Long story short it had never worked anywhere near properly despite countless hours on phones and emails; the best we’d achieved was one third of the batteries working. Rather than write it off, I asked a PM friend to try to source someone who could come on site and review and revive the system. He found Solar Tech Support and Ron. Ron assured us he was the man to get it going again. After so many years of pain, I was not convinced but, true to his word, five hours later it was up and running. Lovely chap, super knowledgeable with a support team to lean on who are also clearly super technical. I honestly didn’t think there was much chance of getting this array going ever again so was absolutely delighted when Ron and team pulled it off. Bravo!

Ron is a super star. Two months ago my GivEnergy battery failed a firmware upgrade leaving it a brick. My installer couldn't/wouldn't fix it. GivEnergy couldn't/wouldn't fix it. Then they went into administration and all hope was lost. A flurry of emails later and Ron had diagnosed the fault (failed USB flash drive, something I'd suspected) and talked me through resolving it. Two months of nothing resolved in about 3 hours. It's great to work with someone who pays attention to the details, knows that they're doing (not just following a script) and gets stuff sorted without a fuss or up-charging.

Excellent service from Solar Tech Support. Extremely quick to respond, easy to deal with and clearly very talented engineers. They were persistent throughout a complex GivEnergy battery issue and resolved everything completely. Highly knowledgeable, professional and reassuring support from start to finish. Highly recommended.

Wakefield context
Thousands of government-scheme systems still exporting for free — battery changes that
The Wakefield district was a major beneficiary of government solar schemes, with Mark Group installing Fronius and Solis string inverters on thousands of 2–4 kW arrays between 2010 and 2014. These systems are still generating, but without battery storage they export surplus electricity for pennies and buy it back at full price in the evening. A 5 kWh battery on a typical Wakefield 3 kW system shifts 60–80% of that surplus into self-consumption — the payback period is usually under 5 years.

Typical end-to-end timeline from consultation to operational battery in the Wakefield area, unless the standard G99 route applies (the DNO can take up to 45 working days)
If you're on a time-of-use tariff like Octopus Flux or Intelligent Go, a battery does even more — charging from cheap overnight electricity and discharging during peak hours. Combined with solar generation, this can reduce grid purchases by 70–90% in summer months.
Brand compatibility
Battery retrofit for the inverter brands common across Wakefield
The Wakefield district's inverter landscape is dominated by two groups: original Mark Group installs (Fronius, Solis) and more recent GivEnergy battery retrofits. Here's how battery installation works for each.
Fronius IG / Primo — the original Mark Group inverter
The most common inverter across Wakefield's government-scheme installs. AC coupling a battery alongside a healthy Fronius is straightforward — the battery connects to the consumer unit independently and your Fronius continues generating as normal. If your Fronius is approaching 10+ years and showing faults, replacing it with a hybrid inverter and DC-coupled battery in one visit saves a second installation.
Solis string inverters — the other Mark Group staple
Solis 2.5G and 4G mini inverters were the second most common Mark Group installation across the Wakefield district. Like Fronius, these are solar-only string inverters that pair easily with an AC-coupled battery. No changes needed to the existing system. If the Solis is still performing well, AC coupling is the cheapest route. If it's failing, the DC-coupled hybrid upgrade makes more financial sense.
Already have GivEnergy? Expand or optimise your storage
GivEnergy is now the dominant battery brand in the Wakefield area, usually retrofitted onto older solar systems. If you already have a GivEnergy AIO or hybrid and want more capacity, we add slave battery modules — no new inverter needed. If your GivEnergy system isn't performing as expected, we diagnose and reconfigure before recommending additional hardware. GivEnergy expansion →
Coupling options
AC or DC coupling? For Wakefield, it depends on your inverter's age
Most Wakefield systems have Fronius or Solis inverters installed 10–12 years ago. If the inverter is healthy, AC coupling is cheaper. If it's on its last legs, DC coupling combines the replacement and battery in one job.
AC Coupling — inverter still healthy
✓Battery connects to consumer unit alongside existing inverter
✓Zero changes to your current solar setup
✓Single day installation — no scaffolding, no roof work
✓From £2,495
DC Coupling — inverter failing or end of life
✓Replaces ageing Fronius/Solis with modern hybrid in one visit
✓Higher efficiency — solar charges battery directly on DC bus
✓Optional EPS backup power included at minimal extra cost
✓From £3,495 including a new hybrid inverter and battery
Wakefield recommendation: If your Fronius or Solis is still generating cleanly after 10+ years, AC coupling is the cheaper, faster route — keep the existing inverter and add a standalone battery. If the inverter is throwing faults, showing reduced output, or already dead, DC coupling with a hybrid inverter is the smarter investment. A free remote assessment tells you exactly where you stand.

Mark Group installations
Mark Group system in Wakefield? Your panels are fine — the inverter might not be
Mark Group installed thousands of solar systems across the Wakefield district between 2010 and 2014 under government energy efficiency programmes. The panels are typically still performing well after 10+ years, but the Fronius IG and Solis string inverters are reaching end of life — intermittent shutdowns, reduced output, or fault codes are common. Adding a battery at the same time as replacing the inverter is the most cost-effective upgrade path. One visit, one project, one commissioning.

Adding a battery in Wakefield — common questions
AC-coupled battery installation in the Wakefield district costs from £2,495 for a 5 kWh system — fully installed and commissioned with DNO G98/G99 paperwork handled. DC-coupled installations — where we replace your existing inverter with a hybrid model and add battery together — from £3,495. The DC route often makes more sense in Wakefield where many original Fronius or Solis inverters are reaching end of life. Full battery guide →
No. Adding a battery to an existing FiT-registered system does not change your tariff payments. You continue to receive generation and export payments as before. Many Wakefield systems were installed under the FiT scheme between 2010 and 2014 — the tariff is protected regardless of what upgrades you make to the system afterwards. The only requirement is the DNO paperwork (a G98 notification, or a G99 application if the total goes past 16 A per phase), which we handle as part of every installation. Book a consultation →
If your Fronius or Solis inverter is showing faults, reduced output, or intermittent shutdowns after 10+ years, combining the replacement with a battery is usually the best value option. A like-for-like string inverter replacement costs from £995. But for roughly the cost difference, you can upgrade to a hybrid inverter that handles both solar generation and battery storage — plus optional EPS backup power. One installation visit covers everything.
