myenergi libbi for a no solar in Birmingham
Updated
With no useful roof, a myenergi libbi in Birmingham earns money only if the charge rate stays well below the rate avoided later. Treat myenergi libbi here as a tariff tool for Birmingham, or do not fit it.
myenergi libbi on a no solar in Birmingham
Driveway semis in the suburbs hide the real argument, which is whether the consumer unit has a spare way, which is the constraint I would write next to myenergi libbi for this no solar.
National Grid Electricity Distribution covers this Birmingham example. A 4 kWp-class roof at 930 kWh per kilowatt is about 2,790 kWh a year before shade, and myenergi libbi does not change that weather.
Money for myenergi libbi for a no solar in Birmingham
Take a 13.5 kWh pack, cycled about 260 times, at 90% round trip. Charge at 13.0p, and value what comes back at 26.0p. Export given up is priced at 4.0p. There are no panels beside this 13.5 kWh pack, so every unit charged comes off the grid. Delivered energy is about 3159 kWh. After charging cost and lost export, the figure saves about £365 a year. Set that against £6,474 fitted, which is a September 2026 illustration at the temporary 0% residential rate, not a quote. That is a simple payback of about 17.7 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 £6,474 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 no solar in Birmingham
In Birmingham, on National Grid Electricity Distribution, 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 13.5 kWh and 0 kWp, which is enough to tell two quotes apart if they assumed something else.
In Birmingham, 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 no solar in Birmingham?
I would not compare a £6,474 headline with another until usable kWh and the fate of any existing inverter match.
I would proceed on myenergi libbi for a no solar in Birmingham 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. £6,474 is a September 2026 illustration for a 13.5 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 13.5 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 £6,474 job, that folder is part of what you bought.
What if the cheap rate is not 7p?
Then the figure changes. This page used 13.0p 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.
