SolarEdge Home Battery for a heat pump in Sheffield
Updated
A SolarEdge Home Battery will not run a heat pump through a cold Sheffield evening from 8 kWh. It can shift a slice of the Sheffield load into a cheaper window, and that slice is the only honest sale.
SolarEdge Home Battery on a heat pump in Sheffield
One street has a clear south pitch and the next sits in shade by mid-afternoon. The survey has to stand in the garden, which is the constraint I would write next to SolarEdge Home Battery for this heat pump.
Northern Powergrid covers this Sheffield example. A 4 kWp-class roof at 880 kWh per kilowatt is about 2,640 kWh a year before shade, and SolarEdge Home Battery does not change that weather.
Money for SolarEdge Home Battery for a heat pump in Sheffield
Take an 8 kWh pack, cycled about 260 times, at 90% round trip. Charge at 9.0p, and value what comes back at 26.0p. Export given up is priced at 4.0p. About 743 kWh a year of the charge is treated as spare solar from 2.5 kWp that might otherwise have been exported. Delivered energy is about 1872 kWh. After charging cost and lost export, the figure saves about £343 a year. Set that against £5,686 fitted, which is a September 2026 illustration at the temporary 0% residential rate, not a quote. That is a simple payback of about 16.6 years, which is past a typical 10-year warranty. Nudge the night rate up by 4p and see if you still like it.
Where the job is a qualifying install in a home, the 0% rate runs to 31 March 2027 and is due to become 5% after that. This figure prices the work at £5,686 on that basis. It does not apply to a shop, and it does not apply to a battery you buy and fit yourself.
Connection for SolarEdge Home Battery for a heat pump in Sheffield
In Sheffield, on Northern Powergrid, 5 kW sits above the 3.68 kW G98 line, so this wants a G99 application before anyone energises it. Export can still be capped. Agree that before the inverter is ordered. The figure uses 8 kWh and 2.5 kWp, which is enough to tell two quotes apart if they assumed something else.
In Sheffield, the weak case for SolarEdge Home Battery is simple: Mixed-brand roofs and anyone told they must replace working optimisers without a reason.
Would I proceed with SolarEdge Home Battery for a heat pump in Sheffield?
I would not treat backup as included on a 8 kWh quote unless the circuits are listed.
I would proceed on SolarEdge Home Battery for a heat pump in Sheffield only after the cupboard, the 5 kW connection route and the tariff gap are written down.
Common questions
Is the price on this page a quote?
No. £5,686 is a September 2026 illustration for a 8 kWh example at the temporary 0% residential rate. Your survey replaces it.
Will it stay on in a power cut?
Only if a gateway or essential-load board was designed and paid for. A standard grid-tied battery turns off with the grid. On this 8 kWh example the inverter is 5 kW, and backup is still a separate line.
What paperwork should I keep?
Keep the MCS certificate where the job is certified, the electrical certificate, the DNO record, the schematic, the warranty registration and a photo of the schedule. For an illustrated £5,686 job, that folder is part of what you bought.
What if the cheap rate is not 7p?
Then the figure changes. This page used 9.0p as a charge rate and 26.0p as the rate avoided. A smaller gap means a worse payback. Read the live tariff.

The figures above are a rough guide. An installer still needs to see your fuse board, where the battery will go, and whether you want power during a blackout.
