Untethered home charger help
Discussion
Hey,
We've just ordered our first EV (BYD Atto 3 Evo Excellence) and need to get a home charger installed. Will be using Intelligent Octopus Go tariff most likely. We don't have solar/batteries currently, but are planning on getting some installed in the near future. I was looking at the Ohme ePod, but just read that it isn't compatible with batteries, just solar. The Hypervolt is compatible with both solar and batteries, but is tethered. We need untethered as I don't want a post in the driveway, and the closest point on the house to where the car can be parked is about 12m.
Does anybody have any recommendations for a charge point that fits the above?

So when it says it isn't compatible with batteries, what does that actually mean? It won't charge from the batteries? I hadn't thought about battery sizes, I'm not clued up on those systems either, but assumed that if the batteries were full and solar was good, I'd be able to charge from the batteries/solar during the day for free basically?
Most people want their home battery to be used for the home and not the car, so it is undesirable to charge the car using the home battery. Actually it is also better to export solar rather than charge the car with it, as on Octopus IOG export is 12p/kWh and off-peak is 7p/kWh.
Where did you read about the Ohme epod and batteries? Perhaps I can make sense of it.
I have just had an Ohme ePod and Solar and batteries installed.
My understanding is the car will draw from the batteries even if you don t want it to. That s the issue.
I haven t yet used it in anger yet as the house is a building site with a skip on the drive, so unable to confirm as yet.
This is the option I have on my ePod. So it will charge the car when there is either 0.72kw or 1.44kw spare capacity in the solar.
So it will directly charge the car when producing excess solar. However, if your batteries are also topped up it sees that as ‘excess’, so will drain them if there is not enough solar.

That makes sense thank youWhere did you read about the Ohme epod and batteries? Perhaps I can make sense of it.
I read it in the comparison table at the bottom here: https://octopus.energy/Our-Chargers/

So if your batteries are topped up and you're not producing the required excess from the solar, is not better to charge direct from the grid overnight at a reduced rate? Is that how IOG works? Will charge the car at cheap rate when there is excess in the grid (usually overnight as I understand it)My understanding is the car will draw from the batteries even if you don t want it to.
