EcoFlow Stream "plugin" solar

Magnitio

Maybe this discussion was covered elsewhere, but are these units legal in UK to plug in to a mains socket? Even after 27th August?

No and no.

They're not covered by the interim product specification (IPS). The IPS excludes battery storage systems.

They do have the necessary approvals for use as a hard-wired installation, rather than plugin - hence the inverted commas in my thread title. And plugin batteries remain under consideration by the Government for future expansion of the scheme.

I've added a note to the opening post to explain this.

Just in case anyone other than me is interested, here's an end-of-August update:

Total outputs by month, per the EcoFlow app:

• April - 20kWh (one panel, lying mostly flat and shaded for all morning, for half the month).
• May - 164kWh (all four panels on the shed roof from the 12th).
• June - 206kWh, 114 Os.
• July - 249kWh, 138 Os.
• August - 199kWh, 111 Os.

Since installation, we've so far generated ~844kWh from this kit despite its less-than-ideal location with panels split roughly N-S on a shallow-pitched shed roof that's shaded by trees from mid-afternoon. It's also limited by the 800 watt inverter, which means it clips quite heavily once the battery is full.

I should let you know how September went - and it went quite well!

For the whole month, the Ecoflow system on my shed roof generated 129 kWh, 72 Os. The system's best day was 05/09 (7.1kWh, 3.9 Os), while the worst day was 08/09 (1.9 kWh, 1.1 Os).

As of the end of September, it had generated 973kWh.

We're now into the "dark" months and it will be interesting to see how much of a contribution it can make through late autumn and winter. I'll keep this thread updated with results.
