Octopus Flux tariff from April

[Stinsy]

Hello,
The announcement from Octopus that their night-time charge rate will be significantly less than the day-time export rate was a surprise and has prompted me to search for answers to the following question.

Can anyone tell me if the Tesla gateway assesses the next day sunshine forecast to decide whether to charge the batteries in the night or to leave them in whatever partial charge state they are in?

My daily consumption rates vary from 14kWh to 60 kWh per day and the 3x batteries have approx 40kWh storage. In the summer the PV system exceeds my load, but not in the winter.

Many thanks,

David

I don’t know that anyone else on this forum has a Tesla house battery. I know that Victron and SMA kit has this functionality built in. Additionally you can implement it with HomeAssistant or Node Red on many inverters. This is a sought-after feature for those who don’t get paid for exporting.

Why not just fill your battery on cheap rate and export it all in the premium slot?

The SMA Sunny Island does not have this for overnight charging, although if you read the docs, it reads like it does.

I have a Tesla Powerwall 2 but without the gateway, it charges completely during the cheap rate and I find now that it mainly discharges from around 8pm, it is set for Time-Based Control, Energy Exports set to Everything and Grid charging enabled.

I don't know if it does access a local sunshine forecast but the algorithm does adapt depending on your usage and the amount of solar input.

My Tesla Powerwall now "sits behind" a Victron system that controls any export to the grid.
