Today's generation was 22.63kWh, Battery fully charged and 3kW exported. @katie279 is quiet lately 
might as well make the most of it before she gets all them extra panels installed 
I'm very pleased, still needs some fine tuning on the settings relating to charging/discharging the battery, but its getting there. Very pleased with the generation, should be well over producing come the summer, just hope I can get on to Flux
As for PV Output, I'm working on it, I set up Home Assistant yesterday, then thought I really should be able to do this on the Victron Cerbo, Goolged and found this thread, I had seen this a couple of weeks ago, but someone has updated it with something I can hopefully get working.
Potentially ordering the cells for the second battery tomorrow, but delivery won't be until late April.

Seriously though you must be so chuffed that your hard work has paid off so well.

Didn't quite achieve the Ronski 20kWh today.

I get blamed for everything these days! I was at Crieff Hydro getting pampered! (Although I might have peeked a few times at my solar generation whilst away.... )

March target is a tough one at 285kwh…almost double februarys target
Soldato
Cant see much solar getting through the pea soup today.....its greyer than john major out there lol
What are your targets based upon out of interest? the data your installers provided?
Soldato
Its based on this companies predictions of what my system should produce from what my installers told me
Solar Power Calculator breakdown by month
See how much solar energy you will generate across the year with this monthly breakdown graph. Check to see if you are on target throughout the year.

I've a target of 512kWh for March. Obviously the weather forecast for the next two weeks pretty much says thats not going to happen.
Soldato
how big a system??
Associate
6.56kW

I'm hoping I'll be getting more than march 334 for Feb. I doubt I'll get 500... But who knows!
Soldato
so double the size of mine....so if you double my target of 285, then thats 570....so your target of 512 may be a little low

My target moves from 175 in feb to 343 in Mar. Feb actual will be around 225, although it does feel like it was a good month.
Mine is based on a typical UK profile and 3900 annual generation if that helps.

yours are all just slightly higher then mine, based on system size.....My feb target was 146 and we are at 178 at the moment

Your south facing though right?
I think my scaling will be a bit out as I am probably more significantly hit in winter months being west facing
these are just starting values for me as i get actual months come in I am averaging this with actual for 24 targets and will do same for 25. Then 26 onwards will just be my last 3 year average as my target.
Should be close enough for decision making on tariffs (etc)
I've had the following actual generation for March from a 4kw system, have got figures going back to 2016 but the app doesn't show them.
2019 334 kWh
2020 430 kWh
2021 360 kWh
2022 390 kWh

yes predominantly south facing, maybe a few degrees off perfect.....but i do get the sun at the front of the house in summer from around 6am to 9pm and the panels are on the front elevation

Useful comparator.
I should be about 20% down on them due to facing, but about 20% up based on array size.
Which means those numbers (avg. 378) puts my 343 firmly in the cautious achievable range.
