myenergi libbi for a small terrace in Southampton
Updated
A small terrace in Southampton needs a cupboard that meets the myenergi libbi datasheet. Do not import a detached-house cabinet into Southampton just because the brand is familiar.

Southern yield helps the annual figure. It does not retire the winter tariff, which is the constraint I would write next to myenergi libbi for this small terrace.
SSEN covers this Southampton example. A 4 kWp-class roof at 1040 kWh per kilowatt is about 4,160 kWh a year before shade, and myenergi libbi does not change that weather.
Money for myenergi libbi for a small terrace in Southampton
Take a 10 kWh pack, cycled about 280 times, at 90% round trip. Charge at 11.0p, and value what comes back at 27.2p. Export given up is priced at 6.0p. About 1600 kWh a year of the charge is treated as spare solar from 4 kWp that might otherwise have been exported. Delivered energy is about 2520 kWh. After charging cost and lost export, the figure saves about £477 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 14.9 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 myenergi libbi for a small terrace in Southampton
In Southampton, on SSEN, 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 Southampton, the weak case for myenergi libbi is simple: Households shopping purely on the lowest price per kilowatt-hour with no interest in the myenergi stack.
Would I proceed with myenergi libbi for a small terrace in Southampton?
I would not treat backup as included on a 10 kWh quote unless the circuits are listed.
I would proceed on myenergi libbi for a small terrace in Southampton 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 27.2p 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.
