Best power provider for EV?
Discussion
Yeah, Octopus Go, or Octopus Go Faster, possibly Intelligent Octopus.
I use a Zappi, getting 7.2kw storage and 4.75kw solar in two weeks time. But this set up excludes me from Intelligent Octopus
I will hopefully be able to use the offpeak to charge the battery and car until April, then solar to do both, sunny days should yield 1/3 of a charge
The challenge will be balancing the charging of the battery, and to some extent the EV leaving enough room in each to fill the battery from solar the next day if some charging happens overnight.
The reality is not seen anyone in the market who can do this really well and I develop EV chargers :-D

BertBert happy to recommend a friend of mine who is currently setting up my house. Zappi charger and new distribution board in so far. Batteries and inverters have arrived and awaiting installation. Solar panels going up in March and (hopefully) car arriving May! Also installing 2 heat pumps and Home Assistant to control it all.

Why does it exclude you from Intelligent? I’m on Intelligent and have a hybrid solar PV and 7Kw~ battery system.I use a Zappi, getting 7.2kw storage and 4.75kw solar in two weeks time. But this set up excludes me from Intelligent Octopus

You can’t be on an export tariff AND intelligent, but I’ve got no issues being on intelligent with my setup, I just don’t get paid for excess generation exports.

I assume any excess solar tops up the battery during the day, and assuming the battery isn't full from that, it gets filled with grid power during the cheap hours? IE you never need to pay for any peak rate power because all day the house is powered by the battery/solar?
Correct, excess generation is either taken by the Zappi or dumped into the hybrid battery for consumption later. And also yes, I fully charge the battery overnight (at the 7.5p/kwh rate) which I then consume until the sun rises and after the sun sets (or during overcast days). Not quite staying off the “expensive” rate juice completely, but tend to get to around 9pm on a sunny winters day, and 5:30pm on an overcast one.
Only had the system since early December, so yet to see what will happen in summer.
We have one EV and one PHEV that we dump excess generation into.

Thanks, looks like Octopus
seem to tick all the righrboxes.
Only issue is smets1 meters. The ones absolutely guaranteed to be updated/replaced by 31dec22.
Hah
just signed up and added Intelligent tariff with Smets 1 meter and hod no problems - if its capable of 30 minute readings, mine worked fine
