Add Battery to Existing Solar in Yorkshire
Yorkshire has one of the highest concentrations of FiT-era solar-only systems in the country — thousands of 2–4 kW arrays installed between 2010 and 2015 that generate well but export most of their output to the grid. Adding battery storage lets you keep that energy for evening use instead. For most Yorkshire systems, AC coupling is the right approach: you keep your existing inverter and add a battery unit alongside it. No rewiring, no inverter replacement, no FiT disruption.
Tell us your current inverter brand and model, your approximate daily electricity usage, and whether you're on a time-of-use tariff. We'll recommend the right battery size, coupling method, and provide a written quote.

Yorkshire saw massive residential solar uptake during the Feed-in Tariff era. Thousands of 2–4 kW arrays were installed through government-backed schemes by Mark Group, Solarplicity, All Seasons Energy, and smaller regional firms. Those systems are still generating well — solar panels typically last 25+ years — but the homeowners are exporting most of that energy to the grid at a fraction of the retail price. A battery changes the equation: store surplus daytime generation and use it in the evening when electricity costs the most. On a time-of-use tariff like Octopus Flux or Intelligent Go, the payback is even faster.

Your generation tariff payments continue unchanged — battery doesn't affect registration
The financial case is strongest for homeowners on higher FiT generation tariffs (15–43p/kWh) who are currently exporting surplus at just 4–5p/kWh. Storing that energy in a battery and using it at night — when retail electricity costs 24–30p/kWh — effectively triples the value of every surplus kilowatt-hour. For a typical 3 kW Yorkshire system generating 2,800 kWh/year, a 5 kWh battery can recover £300–500/year in avoided grid purchases.
AC coupling vs DC coupling — which one for your system?
For the vast majority of Yorkshire's FiT-era solar-only systems, AC coupling is the right choice. Here's the quick comparison.
Our recommendation for Yorkshire FiT systems: Start with AC coupling. It's cheaper, simpler, and your existing solar inverter keeps working exactly as before. DC coupling only makes sense if your inverter has already failed (combine the swap with a battery addition) or if you specifically want a single-brand unified system. Full technical guide →
Battery systems we install across Yorkshire
We work with all major battery brands and recommend based on your existing inverter, usage pattern, and budget — not on commission or installer partnerships.
All-in-one battery inverter with 4.8 or 9.5 kWh storage. The most popular AC-coupled retrofit unit in Yorkshire. Handles solar diversion, timed charging, and export limiting in one box. Optional EPS backup with proper wiring.
Hybrid inverter with modular ARK battery. Good for both AC and DC coupling configurations. Scalable from 5 kWh to 25 kWh+ with stacked battery modules. Strong warranty terms.
Compact hybrid inverter with T-BAT modular lithium battery. Quiet operation and a solid app-based monitoring platform. Works well in smaller consumer unit spaces.
All viable AC and DC coupling options with EPS capability. We install and configure all three across Yorkshire. Brand choice depends on your existing inverter, consumer unit layout, and preferred monitoring platform.

Battery retrofit pricing across Yorkshire
GivEnergy AIO or equivalent. Ideal starting point for a 2–3 kW FiT system. Covers evening usage for most two- to three-bedroom homes.
Larger storage for higher usage homes or time-of-use tariff optimisation. Stores enough to cover overnight usage and morning peaks.
Hybrid inverter + battery. The right choice if your existing inverter has failed and you want to combine the replacement with storage in one visit.
All prices include hardware, installation, commissioning, DNO G99 variation, and post-installation report. No hidden extras. Full battery retrofit guide with technical details →

AC-coupled battery retrofits — where you keep your existing solar inverter and add a battery unit alongside it — start from £2,995 installed for a 5 kWh system. Larger 10 kWh systems run £4,500–7,000 depending on the brand and configuration. DC-coupled retrofits that involve replacing your string inverter with a hybrid model cost £7,000–12,000 including both the new inverter and battery. For most Yorkshire FiT-era systems, AC coupling is the cheaper and simpler option. A £75 system assessment confirms which approach suits your setup.
Yes — that's AC coupling, and it's what we recommend for most Yorkshire systems. You add a separate battery inverter (such as a GivEnergy AIO or Growatt SPH) alongside your current string inverter. Both operate independently. Your existing solar setup stays exactly as it is — no rewiring, no reprogramming, no downtime. The battery unit handles its own solar diversion, timed charging, and export management. Full AC vs DC coupling guide →
Your FiT generation tariff is unaffected — you still earn per kWh generated regardless of whether that energy goes to the house, the battery, or the grid. Your export tariff depends on whether you're on deemed or metered export. For most FiT systems on deemed export, adding a battery actually improves your financial return because you're using more of your own generation instead of exporting at the lower rate. We confirm the specific FiT implications for your registration before any work starts.
An AC-coupled battery retrofit is a single-day on-site job — mounting the battery unit, running cables to the consumer unit, installing the CT clamp, commissioning the battery inverter, and testing charge/discharge cycles. DC-coupled installs that also involve an inverter swap take a full day or occasionally stretch to two. The DNO G99 variation paperwork is submitted before the install date and usually approved within 2–4 weeks. From initial consultation to a working battery, most Yorkshire installations are complete within 3–4 weeks end to end.
