    Hi

    I'd need to see detailed specs (including the missing efficiency, size etc) before having any thoughts other than "it looks good" ... mind though, from the pictures it does seem pretty small for a 2.2kWh module ... approx 3'x3' (guess) x ~2.5" deep (spec) ...

    From the description (self islanding etc), it looks to be more of an in-line UPS for dedicated circuits than anything else ... I'd be interested to see details about discharge operating temperatures etc too if mounting in a main living area (decoration discolouration etc) ...

    Certainly an interesting option for domestic refrigeration & living room entertainment systems/lamps etc, but doesn't look like it's even looking to be a whole house solution so it's likely that most homes would need multiple units ...

    Worth keeping an eye on for future developments or similar products, but I'm not going to get excited at the moment ..

    Just to say I've copied this onto the domestic battery thread as it's another interesting one to watch / be aware of.

    Interesting times.

    [FONT=Verdana, sans-serif]So does the storage unit feed electricity back into the ring it is plugged into ie you could plug it in anywhere on your downstairs ring then use the store next day anywhere else on that ring?[/FONT]
    [FONT=Verdana, sans-serif]Looks bulky and there is bound to be some efficiency loss, also the ratio between night and day rates is not as good as it used to be.[/FONT]

    Hi

    Details say that it doesn't export to the grid and islands in the case of a power loss. This suggests that it's more akin to a UPS which is plugged into the mains where all downstream load is connected to the unit and switched between mains & battery as necessary just as a near-line UPS would ...

    To feed the entire house from a plugged-in unit there would be a legal requirement to automatically & immediately disconnect the house from the grid in the event of grid supply failure. This would logically need the installation of automated monitoring & isolation switching between the meter & the distribution board which would need to be connected by a suitably qualified person ... the product is shipped as a plug&play consumer item therefore it's pretty safe to conclude that this is not the case (at the moment!) ...

    If you don't know what a UPS is - think of it as being a power extension lead with batteries & electronics!

    Regarding 'bulky' ... considering it's 2.2kWh of storage and slimline (only stands 2.5" proud of a wall) I'd have thought that it wasn't ... other units of similar storage capacity tend to look more like small GCH boilers!
