South East rates confirmed

So, June on flux paid £197 (compared with £35 on old deemed). After generation FiT, import and s/c that's ~£271 profit towards the winter bills. Quite pleased.

How are people using this? I've just signed up and have set my batts to discharge during the 16:00 - 19:00 down to a point that I estimated would see us through to the 02:00 - 05:00 flux period (60% of 6 kWh, less if we're going out as the Growatt ShinePhone app makes it easy to change). Charge up in the flux period. I figured most days around this time of year whether you charged or not on the flux rate didn't make much difference either way as the cost of charging (including round trip efficiency losses) is pretty much the same as the extra export income you'll get the next day on the day rate, but if you have really bad day you're better off having charged as you won't risk importing on the peak rate. Also shifting loads that can reasonably be shifted eg dishwasher to the flux rate overnight.

Maybe I'm overthinking this?

All I have is my panels and I run heavy loads overnight and cook the main meal at lunchtime when convenient, or as with tonight, have a barbecue at tea time.

Exactly what I do, but with 29kWh of batteries. I discharge to 45% in the peak period, then recharge in the Flux period.

I charge to 90% (I "think" its less stressful for the batteries) then just let everything do its thing.. no forced discharge

When you export from flux, when do you get paid for the electricity to grid?

You get a credit on your account.

Ok, only been on for 2 weeks, just had bill. Shows consumption but no credit that I can see.  Or is credit elsewhere?

It's actually a separate invoice. I get one for gas, another for Flux import and then Flux export.
