Yesterdays lovely looking solar curve
Solar panels and battery - any real world reccomendations?

I'm sure @Peteronthesouthcoast will exceed Katie's generation if his two systems showed combined generation, currently only his original 4kw system is on PV Output.

How are you now @Ron-ski did you get over the flu and further with the setup?

Heheheh! I think I might be going for my first fat zero today - masses of snow overnight, schools closed and kids building a snowman - I'd be amazed if the panels managed anything at all today!
So I'm flipping and seeing if I can get my record low!

This is our time. Southerners unite!

Get the kids on the roof to get the snow off the panels!
Note: this is not parental advice.

there we go, snow stops play for @katie279

I add some charge only if it's low enough to warrant it, we've had enough OK days lately where it's rare that it's needed to do it.

Im same as hippo, add some charge in earlier in the day if i am going to need it, plus of course on savings days I specifically make sure I can guarantee no usage during the window
There is some minor gaming you can do, but its speculative.
My rules are : never charge more than you need to get to the "Go window", the cost of taking full price units does exceeds the value of a savings session unit. (weekday based saving session)
Charge in the likely savings session window rather than being direct grid later. This is the gaming in effect.
As above on a Savings session day charge before the session to ensure have enough to get through the session as a minimum
It has some cost of course its extra battery cycling, albeit pretty minor.
Its a particular issue for me right now with on average pretty low generation and my batteries regularly not being 100% come 4:30. They really don't like these prolonged very low temps.
I expect in normal times far less need for charging.

Yes first time I ever have done it.
Fortunately we had had a sunny day so batteries had plenty of charge.
That's equivalent of £2.26 - so basically a day's worth of electricity.

efficiency has just hit 2kwh/kw for the day and rising.....

Getting a healthy 850w at the moment. Not a lot, but enough to run a dehumidifier, my PC, and top up all the batteries.

All good now thanks, end of my second week back at work, see https://forums.overclockers.co.uk/t...ith-whole-house-backup.18957434/post-36073535 for updates.

Thanks for that.
I am putting data from my "new panels" and will be posting it soon on PV Output under Give Me Sunshine 2

OK I sacked off repurposing an old Pi 2 as its too problematic and wasted enough time. Have Home Assistant on a spare laptop!
Anyone using solis (ginlong)? I see there is no easy integration when I search so might have to get dirty.

Maybe a little...
9848 points in the last session, which is worth about £12.50, and also was exporting at the same time and earned about £6.50 from that.

Oh noes just had the last of the paperwork through from my installer and they didn't fit the panels I had been quoted as they were out of stock
Only noticed as I was fairly certain that they were supposed to fit JA 390s and they mentioned canadian solar
Oh but they are canadian solar 405s instead
System went from 5.46 to 5.67

Canadian solar may be a better brand?

Yeah probably better panels anyway.
6.2KWh today by the way.
