Stored kilowatt-hours only pay back if the house uses them at night · review
A 2240 Wh LiFePO4 balcony storage unit rated IP65, coupled through a micro-inverter, expandable, and installed without an electrician according to its listing.
The bottom line An expandable balcony battery with a published enclosure rating and a clear description of how it works across a day. What it never publishes is a power figure, which leaves the most practical question — what it can actually run — unanswerable from the sheet.
A 2240 Wh balcony storage unit, sold as a plug-and-play addition to an existing micro-inverter.
By day, solar passes through the unit to the micro-inverter and on to the household; with a smart meter fitted, surplus is stored rather than exported. By night, the stored energy is fed back through the micro-inverter. That is a clear description of an AC-coupled arrangement, and it is more than most listings on this shelf provide.
2240 Wh, LiFePO4, 6000 cycles, IP65, and expandability. The enclosure rating matters here: this is a product sold to stand on a balcony.
Any power figure at all. Neither a charge rate nor a discharge rate appears in any bullet, and without them the unit cannot be matched to a load or to an inverter. The cycle count carries neither of its two qualifiers.
Amazon’s catalogue entry for this product carries a broken character in place of an umlaut in the title. It is a fault in the source rather than in the product, and this page reports it rather than reproducing it.
German Amazon store quoted about 311 € when this page was compiled.
French, Italian and Spanish Amazon stores wanted more than 1.6× what the cheapest country wanted. A margin that wide usually means stock shipped in from elsewhere rather than a seller on the ground, so those quotes stay out of the range above.
British Amazon catalogue carries an entry for it, with nobody selling.
American Amazon store returned nothing at all, so the buy button there runs a search instead of landing on an empty page.

| Usable capacity | Nowhere in the listing — 2240 Wh is published as capacity, with no usable figure beside it |
|---|---|
| Charge and discharge power | Nowhere in the listing — no wattage is published in any bullet |
| Chemistry | LiFePO4, stated in the listing title |
| Cycle life | 6000 charge cycles, from the title; no capacity percentage and no depth of discharge accompany the count |
| Inverter compatibility | AC-coupled through a micro-inverter, third and fourth bullets; no specific inverter is named |
| Published metering | A smart meter is described as storing surplus rather than exporting it, third bullet; the meter is not part of the unit |
| Amazon reference | B0F94849NF (same reference on 5 Amazon marketplaces) |
| EAN | 6951525703652 |
Because capacity says how much energy is held and power says how fast it can leave. A 2240 Wh unit that can only discharge slowly covers a fridge overnight; one that can discharge quickly covers a kettle for a few minutes. Neither figure is published here.
That is a claim about the product, not about your local rules. Whether a plug-in storage unit may be connected at all, and under what conditions, is decided by the regulations in force where you are and by your grid operator.
