Solar panel production figures

6.5 today, been a rough day, updated firmware on AIO/Battery last night and it ran its calibration, it took longer to finish completing charge at 100% than it did to get to 100% and somehow on a 13.5kw datasheet battery 15.96 claimed capacity it managed to put 16.5kwh into battery.

Whelp after all was done I only got up to 6.7 generation, was a rough day today lol
 
Been reading about LFP batteries losing capacity as they get colder. I've only had my system since March so not really experienced very cold weather but my batteries are in the garage near the door and so will get quite cold.
Has anybody had any issues with their batteries getting too cold to charge in winter? I was considering making a box for them out of kingspan and perhaps putting a 50w heating element in there for when it gets really cold. Or is it not necessary? Seems to be quite a lot of conflicting info online. Apparently their ideal operating temperature is 27 degrees and they lose 10% capacity for every 10 degrees below that.

10% drop per 10 degrees sounds a lot.
They do not function below 0c. Mine are heated (assuming you have access to the installer menu and can turn them on or off)

I also built a box for mine. There is a flame retarding polystyrene Wickes have. Its almost certainly not going to happen but worth going that way IMO if you are doing anything.
The batteries do generate some heat themselves when working, so if you can insulate them quite well it cannot hurt for the cold months.
Consider the summer as well ofc.

Mine got really cold last year and stopped completely for a couple of days. When they were cold but just within the charging zone they reduced the charge rate.

Thanks, I've taken a look at the specs of my Sunsynk batteries and they definitely don't mention heating. If yours stopped working last year then mine probably will too. I've already got the battery temperature in Home Assistant so should be able to turn on a little heating element with a smart plug when it drops below 5 degrees.
I'll take a look at Wickes. I would hope kingspan would be flame retardant but I'll check first. I certainly don't want to surround the batteries with kindling!
 
2.3 so far atm EEK but still if I can cover home usage whilst there is daylight im a happy chappy.

I really hate that this seems to be the only place I can't CTRL+V images lol

Been quite the rollercoaster month, total so far 413kwh.
