Pylontech for a EV household in Brighton
Updated
The car and the Pylontech will want the same cheap hours in Brighton. Decide which load is fed first, or the Brighton payback for Pylontech is fiction.
Pylontech on a EV household in Brighton
Regency conversions stop more jobs than the price of the cells. Ask the freeholder before you fall in love with a cabinet, which is the constraint I would write next to Pylontech for this EV household.
UK Power Networks covers this Brighton example. A 4 kWp-class roof at 1030 kWh per kilowatt is about 4,120 kWh a year before shade, and Pylontech does not change that weather.
Money for Pylontech for a EV household in Brighton
Take a 10 kWh pack, cycled about 320 times, at 90% round trip. Charge at 11.0p, and value what comes back at 29.6p. Export given up is priced at 10.0p. About 1829 kWh a year of the charge is treated as spare solar from 4 kWp that might otherwise have been exported. Delivered energy is about 2880 kWh. After charging cost and lost export, the figure saves about £555 a year. Set that against £7,430 fitted, which is a September 2026 illustration at the temporary 0% residential rate, not a quote. That is a simple payback of about 13.4 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 £7,430 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 Pylontech for a EV household in Brighton
In Brighton, on UK Power Networks, 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 Brighton, the weak case for Pylontech is simple: Hallway cupboards, listed interiors and buyers who want a single furniture-grade cabinet.
Would I proceed with Pylontech for a EV household in Brighton?
I would not pay the bulk of £7,430 before the DNO route for a 3.6 kW inverter is known.
I would proceed on Pylontech for a EV household in Brighton 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. £7,430 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 £7,430 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 29.6p 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.
