I cannot see for the life of me how this device can work in harmony with Solar PV excess production i.e. how does it know when you are exporting to grid and divert that into its lithium batteries  Huh

... interesting  ,  but not available yet

I guess it just has a small charger and a small GTI to feed the grid from the battery then... but me not sure ...

similar like this idea  of  a  small and  clever company , i know    ...http://www.solarelectrix.de/home2,4_uk.html

ElectricX looks more promising, whereas the Orison does not mention how it would measure export/import...

Anything exporting power through a plugtop back into a wall socket would also be illegal in the UK, I think?

And you'd require a competent person anyway to make whatever arrangements are necessary to island the system in the event of a power cut so that it didn't feed power back into the mains supply.

So I don't see how you could have a plug and play battery in the UK, or anywhere else for that matter.

.... i guess it should be legalized , to connect a pv or and  battery store to a house socket  at a small scale ..


good idea  to take midday power peaks   at low cost and   release it into the home when prices  are higher ....   in pricip;le   not a bad plan

Usual poor reporting by uninformed journalists

Looks more like an uninterruptable power suupply:-

"The secret to success for Orison is the proprietary software and power electronics technology that help isolate or “island” the connected electrical circuit, says Clifton. The company will rely on outside manufacturers to keep up with the latest battery technology and safety, he says."

Well that's what I thought at first but the diagrams clearly show power being passed back into the mains supply, and they talk about solar power.

Probably you plug a device into the unit if the power fails or if you want to run a TV at night etc.

Doesn't appear now to be a "pukka" solar storage solution after all..

In a power cut the grid is almost a dead short, any battery inverter still connected will instantly overload and cutout. If you turned off the mains breaker then an Inverter could run your house......

Typical you only get enough information to make you worry that the kit is unsafe!!!
