If you are talking retirement, trust me, those extra hours just don’t existThank you very muchly. We are also moving into the other universe with more hours in our day. The hubby will be tracking everything so I will make sure he sees your numbers
I'm a complete nerd and track all this stuff! One advantage of being retired - plenty time to play around with these things!
I have absolutely no idea how much Car Charging I did on the 7kW Ev Charger, as it's connected to the Powerwalls. So I've no way of telling how much of it is from Solar, and how much of it was low-tariff Grid Import Storage.
Nope! My days of deadlines, sprints, stand-ups, reviews, etc, are over!Available for hire?
That's also my assumption. I have a home-made power monitor measuring current/voltage to both my Tesla Wall Connectors. That feeds data back to an MQTT broker, to be distributed to various other processes. I also feed the MQTT broker with realtime data from the Powerwall's local API. Another process subscribes to MQTT to generate a .CSV file per day, plus daily/monthly summaries (for my wife's benefit - she's a bit of a spreadsheet wiz).I am taking the view that charging during daylight hours is PV (might be PowerWall, but most likely that is just balancing during charging so either came from PV or will be replenished from PV that day). But I'd like better quality data in that regard ...

we'd be topping up about 20-30 miles range most days at home
It depends on how much day rate consumption your household (without car) uses. For the car consumption, with some leeway and losses added in, say 3000kWh annually which you can stick in your calculation entirely (hopefully) at the night rate. (You may be able to reduce your household day rate consumption by running some high consumption items during the night rate period too.) For equal ratio of daytime/night rate consumption you will be slightly worse off on the GoElectric (and even worse still if your day consumption is higher than 3000kWh annually, which it likely is) ... you would have to be using more on the night rate than the day rate to make it work in your favour. (But also bear in mind this may depend on you keeping your BG tariff longterm.)I'm investigating moving to an EV tariff but by logic I think I'd be worse off than just sticking to my British Gas tariff? Here is a rough example:

Obviously the night rate is much better so charging my car would be cheaper on the EV tariff but the day rate and daily standard charge are so much higher I think I'd be worse off in terms of my total electricity bill. Am I wrong?
Oh and for clarity I think our average mileage each day would be something like 20-30 miles max (apart from the odd road trip every now and then when we'd probably be using a SuC anyway) so we'd be topping up about 20-30 miles range most days at home.
There are more than a few pocket protectors in this group... saying that, it is great to see different numbers being shared.
I am a little disappointed to hear about the lack of monitoring - this is mainly on individual component consumptions right? We have nice app for monitoring the PV but I thought the Gateway was the answer?
We won't really know how ours all goes together till the Powerwall is installed in May (we will believe it when we actually see it, delivery was promised early this year).
Second question was - those of you with two Powerwalls, are you in the north? Or was the thinking that extra storage capacity was really necessary based on consumption?

I’m in North Norfolk. My issue is shading from surrounding trees during the winter months, knocking generation down quite considerably.There are more than a few pocket protectors in this group... saying that, it is great to see different numbers being shared.

even cheaper to use the Tesco 7kw charger while shopping - it's freeCrazy that its cheaper to public charge at a 50kWh charger than use home electricity during the day. I am not even on an EV tarriff and it is still cheaper to use a pod point charger with full fat VAT than the home electric that I also still need to pay a standing charge for the right to use.
I've got the same problem. Winter shading - drops my generation down to 1-2kWh over a entire day (300w peak). While in summer I can do 30-40kWh on a good day, peaking at 6kW.I’m in North Norfolk.

Two gives ample power to get through 24 hours and of course the 10kWh discharge rate.
so in this case you charge your alpha at the same time as your car..? your draw during off peak rate would be at least 10 kwh if I assume correctly?I've got the same problem.

I've got the Alpha ESS 3kW system with 11.5kWh storage now - that's enough to get me through most winter days before the next 00:30-04:30 charge time.
Oh - and you mean 10kW peak discharge rate, not 10kWh. Although I think it's more like 7kW for minutes? 10kW for a few seconds.
As long as we're not running too many appliances at once 3kW is actually good enough for 99% of the day. ie. don't run the dishwasher, washing machine and oven at once. In fact all 3 of those don't use 3kW in our house. The first 2 are 13amp plugs that peak at 2.2kW.
