UK rules check

Rules checked. The maker’s UK instructions require professional hardwiring. This confirms the installation boundary; it is not an independent certification of model-specific grid approval.

Nominal capacity5.024 kWh manufacturer stated capacity; delivered AC energy is lower[1]
Output2,500W base grid-connected output and 2,500W off-grid appliance output[1]
Solar inputNo direct PV inputs on the AC 5000; supported AC-coupled solar is a separate arrangement[1]
Cycle life10,000 cycles (maker figure; check the retention condition in the exact manual)[1]
Backup powerYes. Own AC outlet only; the grid-connected port stops output during an outage[1]
Plug-inUK installation requires a qualified electrician and a hardwired connection; do not assume household-socket feed-in is permitted[1]
ExpandableCompatible extra batteries can change system storage and output; verify the exact combination[1]

The UK manufacturer page requires an electrician and prohibits feeding power into the home through a household socket. Existing solar integration and expansion need model-specific checks.

Who it suits

Who should skip it

What you need

Good points
  • A stated 5.024 kWh base unit
  • AC-coupled approach suits a different use case from the direct-PV STREAM 5000
  • Manufacturer distinguishes base and expanded output limits
Watch out for
  • UK professional installation is required
  • Direct solar inputs belong to a different model
  • Backup power is limited to the supported outlet/installation arrangement

Common questions

Is STREAM AC 5000 the same as STREAM 5000?

No. The AC 5000 is the AC-coupled model, whereas STREAM 5000 has direct solar inputs. Compare exact model names, base units and installation costs.

Does the AC 5000 deliver 3,000W as standard?

The UK FAQ gives a single AC 5000 base unit 2,500W grid-connected and off-grid output. Certain expanded power-pack arrangements can increase this to 3,000W; that is not the bare-unit rating.

Will it keep my home wiring live in a power cut?

The grid-connected port disconnects during an outage. The documented backup is through the supported AC outlet; whole-home backup must not be assumed.
