A hybrid solar inverter lets you store solar power and still export to the grid
A hybrid solar inverter combines a standard solar inverter with a battery inverter in one unit. It manages both solar generation and battery storage from a single device.
A hybrid solar inverter costs £1,200 to £2,500 installed in the UK, plus £1,500 to £4,000 for a battery. It saves £200 to £400 yearly by storing solar power for evening use and optimising time-of-use tariffs.

The Energy Saving Trust states that a typical UK home with a 3.5 kWp solar system and a 4.5 kWh battery can meet around 40-50% of its annual electricity needs from solar (Energy Saving Trust, 2026). This is significantly higher than a standard solar-only system, which typically covers 25-30% of annual usage without storage.
Unlike a standard string inverter, a hybrid unit can charge a battery from solar panels and also draw power from the grid to top up the battery if needed. This allows you to optimise your use of time-of-use tariffs, such as Economy 7 or Octopus Flux, by charging the battery cheaply overnight and using that stored power during expensive peak hours.
A hybrid inverter costs between £1,200 and £2,500 installed, plus the battery
The hybrid inverter itself typically costs £800 to £1,800, with installation adding £400 to £700 (MCS installer directory average quotes, 2026). The total installed cost for the inverter alone is therefore £1,200 to £2,500.
A compatible battery adds £1,500 to £4,000 for a 4.5 to 10 kWh capacity, depending on battery chemistry and brand. Lithium-ion batteries are the most common option for UK homes.
Total system cost for a typical UK retrofit (inverter, battery, and installation) ranges from £2,700 to £6,500 (Energy Saving Trust solar panel cost guide, 2026). This is roughly £1,000 to £2,000 more than a standard string inverter system without battery storage.
A hybrid inverter saves you around £200 to £400 per year on electricity bills
By storing excess solar generation for evening use, a hybrid system reduces the amount of electricity you buy from the grid. With a typical 3.5 kWp system and 4.5 kWh battery, annual savings from self-consumption are estimated at £200 to £400, based on a grid electricity rate of 24p/kWh (Ofgem typical domestic consumption values, 2026).
Additional savings from time-of-use tariffs can add £50 to £150 per year. This works by charging the battery from cheap off-peak grid electricity (e.g., 7p/kWh on Economy 7) and using that stored power during peak-rate periods (e.g., 30p/kWh).
These figures assume you use the stored solar power rather than exporting it. If you export surplus electricity under the Smart Export Guarantee, you receive additional income of 5 to 16p per kWh exported (Ofgem, SEG tariff rates, 2026).
Quick numbers cost, savings, and payback for a hybrid solar inverter system
| Metric | Value (UK 2026) | Source |
|---|---|---|
| Hybrid inverter cost (installed) | £1,200–£2,500 | MCS installer quotes, 2026 |
| Typical battery capacity | 4.5–10 kWh | EST, “Solar panel battery storage” |
| Annual electricity bill saving | £200–£400 | EST, “Solar panel battery storage” |
| Typical payback period | 8–14 years | Calculated from EST savings vs. MCS costs |
| Export tariff (Smart Export Guarantee) | 5–16p/kWh | Ofgem, SEG tariff rates, 2026 |
The payback period for a hybrid inverter system is 8 to 14 years
Based on a total system cost of £3,500 to £6,000 and annual savings of £200 to £400, payback ranges from 8 to 14 years. This is longer than a standard solar-only system, which typically pays back in 6 to 10 years.
The 0% VAT on energy-saving materials, in place until 2027, reduces the upfront cost by 20% (DESNZ, VAT on energy-saving materials, 2026). This shortens the payback period by 1 to 2 years.
The lifespan of a hybrid inverter is typically 10 to 12 years, while the battery lasts 10 to 15 years (Energy Saving Trust battery lifespan guide, 2026). This means you may need to replace the inverter before the battery. Factor this into your payback calculation: if the inverter fails at year 10, your total system cost increases by the replacement inverter cost.
A hybrid inverter is best for homes already planning a battery or on a time-of-use tariff
If you plan to add battery storage within 2 to 3 years, a hybrid inverter is cost-effective because it avoids buying two separate inverters later. Retrofitting a battery to a standard string inverter requires an additional AC-coupled inverter, which adds £500 to £1,000 to the total cost.
Homes on time-of-use tariffs benefit significantly from a hybrid inverter. You can charge the battery from cheap off-peak grid electricity and use that stored power during peak-rate hours (Ofgem, time-of-use tariffs, 2026). This can double your annual savings compared to solar self-consumption alone.
For homes without any plan to add battery storage, a standard string inverter costing £600 to £1,200 is cheaper and simpler. A hybrid inverter adds unnecessary complexity and cost if you never use the battery function.
You must use an MCS-certified installer to qualify for the Smart Export Guarantee
The Smart Export Guarantee (SEG) requires your solar and battery system to be installed by an MCS-certified installer to receive export payments (Ofgem, Smart Export Guarantee, 2026). Without MCS certification, you cannot sell surplus electricity to your supplier.
Hybrid inverters must also be listed on the MCS product database to be eligible for SEG payments. Check the MCS website for certified installers in your area, and look for TrustMark registration for additional consumer protection (TrustMark, 2026).
You can still install a hybrid inverter without MCS certification, but you will not receive export payments. For most homes, the SEG income of 5 to 16p/kWh adds £50 to £150 per year, so losing this makes the payback period significantly longer.
A hybrid inverter does not require a separate battery inverter, simplifying your setup
A hybrid inverter integrates both solar and battery functions in one box. This reduces installation complexity and space requirements compared to a system with separate solar and battery inverters.
You can monitor both solar generation and battery charge and discharge through a single app or display. This makes it easier to track your energy usage and identify problems quickly.
If you already have a standard string inverter and want to add a battery later, an AC-coupled battery (with its own inverter) is the simpler option. You do not need to replace your existing inverter. However, for new installations, a hybrid inverter is more efficient because it avoids the energy losses that occur when converting DC to AC and back again (MCS installation standards, 2026).
