Re: Why the ‘eye-watering’ cost of heat pumps doesn’t add up

IMG_2989.png Well the facts are true; the horrifically high ‘spark gap’ in the UK is why we aren’t all embracing heatpumps. In a perfect world everybody would want to ‘do the right thing’, but financially nudging people to do what you want is a standard government technique - what is Ed Milliband w...

Re: Big roof solar - sharing power...

There's a petition to allow local selling of electricity here - it looks like exactly what would help!
I signed it.

Re: Octopus Go/Go faster - enforcing "EVs only" ??

So my buddy just got go! He’s got a home batt and PV, and was with octopus already, with a smart smets 1 ‘secure’ meter that was correctly sending readings for import and export according to their app. He found an online link to swap to go, said yes to some sort of pdf of terms and conditions that h...

Re: Octopus Go/Go faster - enforcing "EVs only" ??

Anybody recently get Octopus Go, without an EV, and what was your experience? Does Octopus actually care for some reason, or are they ‘helpfully’ trying to avoid inappropriate tariffs for regular electricity users? Asking for a friend who’s just got PV and batts, no EV. Noted that the export rate fo...

Re: How to get zero leccy bill (ex standing charge)

I had a look on the Zappi V2G website: https://www.myenergi.com/news/power-to-the-people-myenergi-starts-work-on-new-v2g-ev-charger/ I think they're showing a tesla 3 or Y connected via an AC cable to a new V2G-Zappi. The only teardown of the internal Tesla charger I've seen showed a uni-directional...

Re: How to get zero leccy bill (ex standing charge)

The best tou tarrifs I’m aware of are Intelligent Octopus Go and Eon next drive V3. IOG requires an EV car test charge every now and then, but the eon one doesn’t need an EV. Octopus Go says it’s an EV tariff, afaik they don’t check; I think they’re just worried about miss-selling a tou tariff, henc...

Re: Upgrading a FIT/MCS PV+ST system to PV only + battery

As Wookey’s-neighbour with a sunsynk+Seplos battery, i thought I’d add a comment about efficiency here. When I first installed this system, it had no PV attached for a month, and it had a mid certified bi directional meter on the AC feed line. I’d definitely recommend a meter, for anyone installing ...

Re: BEV charger questions

We have a Ohme commando (as in, 32A commando plug input). It looks like a granny charger cable, but with a commando plug. It’s got a sim in it, there’s an app, it’s trying far too hard with all the ‘data’ it presents - I don’t think it even has a current sensor inside but it pretends to know how muc...

Re: Problems from EWI

CWI sometimes exposes prior issues with water dripping into a cavity, but it’s the CWI that gets the blame.
Similar to that EWI in a way, just water ingress and poor attention to detail, insulation getting the blame.
I saw the story on the news, very distressing for the family.

Re: Self charging EV

Is that actually a product? Does it have a built in battery - if not, what happens if the available power is below 6Ax110V =660W, which i think is the minimum charge rate into the AC car socket.
