Storage

[The Solar King]

Anybody else looking at becoming a Tesla Authorised reseller?
Have gone through the process of providing loads of evidence to allow for due diligence to get this.
Tesla are determined to keep out any business or organisation that may mis-sell or provide a poor customer experience.

Despite my misgivings about the sheer size of the thing, we are doing our first one in the next couple of weeks.

Was at an energy show last week in Glasgow where people were taking selfies with the battery. Whether or not it is the best solution, it is certainly the best marketed.

Draft IET Storage Code of Practice.

I have a copy of this if anyone is interested. Unable to load to site as it is over 2mb. Tried zipping it but still too large. If anyone would like a copy please PM me.

At the moment the section (10) on G83 permission for AC side coupled systems is unsatisfactory, as the way it is worded would mean a G59 is required every time. My view is this should be termed as an export limit of 16amp. Most 'Behind the Meter' battery systems are designed not to export to the grid. Feel it is incumbent on the equipment manufacturers to provide evidence of this and how it works to satisfy requirements of DNOs, otherwise this would be a major barrier to development of the 'Behind the Meter' storage market.

I have been submitting G59 applications to UK Power Networks to extend 4kW (and below) PV systems by 300 - 500W. It is part of a project installing 35 systems as a trial After confirming that the systems aneed G59 applications they have now told me to use G83 notification after the install. I think they don't want the paperwork.

Tesla Discontinues 10-Kilowatt-Hour Powerwall Home Battery | Greentech Media

Reason :

The problem is that the economics for a lithium-ion backup battery just aren’t that attractive.


Even at Tesla’s low wholesale price, a 500-cycle battery just doesn’t pencil out against the alternatives, especially once the inverter and other system costs are included.


“Even some of the deep cycling lead acid batteries offer 1,000 cycles and cost less than half of the price tag for Tesla Powerwall,” said Ravi Manghani, senior energy storage analyst at GTM Research. “For pure backup applications only providing 500 cycles, lead acid batteries or gensets are way more economical.”

Tesla's 10kWh Powerwall was only ever intended to be a "backup" system, in case of mains loss, not a "storage" solution.....just not viable, especially here in the UK

Any updates on the G59 application of AC coupled storage systems? I've spoken to my local planner at WPD and he was unaware of the requirement and could see no sense in it...

Anyone intrested in installing a tesla power wall in northwest? My own house.
Drop me an PM ,

I could fit if no-one closer wants to. Have installed two and have 6 on order to fit next year (all with Sunny Boy Storage).
Stock of Powerwall 1 is getting low in the UK and not sure if they will ship more as TESLA will start shipping Powerwall 2 next year.

drop me a PM
with your number I will call you

Anybody got experience applying for G59 approval with WPD for battery systems (Sunny Boy and Sunny Island)? Contacts for anyone in WPD who has approved one of these systems would be helpful .
They are currently insisting on application under G100 (export limiting schemes) to verify that the system will not export as its not G100 type approved yet. Anyone got any experience doing G100 witness tests with WPD?
I seem to have submitted the first G59 (and G100) application for a domestic battery storage system in the East Midlands.
Will keep you posted.
