Enphase IQ Battery for a EV household in Salford
Updated
The car and the Enphase IQ Battery will want the same cheap hours in Salford. Decide which load is fed first, or the Salford payback for Enphase IQ Battery is fiction.
Enphase IQ Battery on a EV household in Salford
Quays apartments need a building rule. Older Salford houses need a shade check. Same borough, different job, which is the constraint I would write next to Enphase IQ Battery for this EV household.
Electricity North West covers this Salford example. A 4 kWp-class roof at 900 kWh per kilowatt is about 3,600 kWh a year before shade, and Enphase IQ Battery does not change that weather.
Money for Enphase IQ Battery for a EV household in Salford
Take a 10 kWh pack, cycled about 300 times, at 90% round trip. Charge at 11.0p, and value what comes back at 28.4p. Export given up is priced at 8.0p. About 1714 kWh a year of the charge is treated as spare solar from 4 kWp that might otherwise have been exported. Delivered energy is about 2700 kWh. After charging cost and lost export, the figure saves about £516 a year. Set that against £7,086 fitted, which is a September 2026 illustration at the temporary 0% residential rate, not a quote. That is a simple payback of about 13.7 years on these assumptions. 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 £7,086 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 Enphase IQ Battery for a EV household in Salford
In Salford, on Electricity North West, 3.6 kW is in the band where G98 connect-and-notify is often enough. Export can still be capped. Agree that before the inverter is ordered. The figure uses 10 kWh and 4 kWp, which is enough to tell two quotes apart if they assumed something else.
In Salford, the weak case for Enphase IQ Battery is simple: Unshaded simple roofs where a mainstream hybrid would store the same evening energy for less.
Would I proceed with Enphase IQ Battery for a EV household in Salford?
I would not treat backup as included on a 10 kWh quote unless the circuits are listed.
I would proceed on Enphase IQ Battery for a EV household in Salford only after the cupboard, the 3.6 kW connection route and the tariff gap are written down.
Common questions
Is the price on this page a quote?
No. £7,086 is a September 2026 illustration for a 10 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 10 kWh example the inverter is 3.6 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 £7,086 job, that folder is part of what you bought.
What if the cheap rate is not 7p?
Then the figure changes. This page used 11.0p as a charge rate and 28.4p 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.
