It's a fancy song and dance 'talent' show, no harm in that, but like the OP I don't see what the hype is about. It's rare that a non-English language song makes the charts or gets airtime in the UK, the language barrier means there's naturally not much interest in Eurovision from the UK. Best...

Hi Andy1733, my initial reaction was surprise that 10kWh of battery was enough to run to 6pm in winter, out of interest what was your electricity usage per annum pre-solar install - just trying to compare to my situation where I use about 4000-4200 kWh p.a., and have you changed your usage much...

nah, you're fine John, was trying to pay it back a little after all the help I've had on the forum and thought my hopes had been dashed! Thanks for sharing again, hope you have a good bank holiday weekend.

sigh, oh well, so much for educated guesswork! thanks for putting me straight John

Hi lhudson, youre welcome, not sure I've been of much help.... IIRC user Johnb2713 's posts have had a number of settings imgs posted which may be of help also searching the forum for shinephone app may bring up relevant posts? best of luck

Hi lhudson, welcome. I presume this will be in the timings settings. There have been a fair few posts on this type of when does it charge/discharge thing with helpful resolutions to problems, so I suspect the answer is already here in some form, the SPH series is likely to be pretty similar too...

You're welcome bigvanish I've found it really useful for trying lots of what-if variants, different inverters and panels etc, to improve my understanding and use the data for working out payback times. Warning - it can be quite addictive too! It doesn't yet include anything for scheduled...

Not much at all then! And I had job at the back of my mind that I really ought to work out voltage drop from from loft to shed in case it was too high! I look at midsummers site fairly often but have missed that calculator as its in the off-grid sister site ! Chuckles to self! Thanks for the...

I guessing the optimiser will be something like this? https://midsummerwholesale.co.uk/buy/tigo-optimisers I don't know enough about them to make any meaningful comment... I'm guessing is it will only push the smaller array over start-up voltage once the larger array is getting enough light...

Might be worth investigating a sunamp heat store, use E7 to heat up and release when needed in morning for shower & hot water needs? Might be part of your overall solution? https://midsummerwholesale.co.uk/buy/sunamp-heat-batteries

Best of luck with your build. What does the voltage drop work out at due to the 70m of cable?

Is this the appropriate inverter spec? https://energywiseireland.ie/wp-content/uploads/2021/07/ERGOCELL-Hybrid-Inverter-and-CATL-Battery.pdf MPPT Voltage range 120~550Vd.c. (sic) MPPT Voltage range (full load) 230~550Vd.c. (sic) OK, I think 1st MPPT indicates the operating range of the MPPT...

Does PV1 array ever generate energy or was it just off for a day? There was a case on the forum not too long ago where the installers had forgotten to plug one of the PV strings into the inverter! Do you have any graphs of PV generation? If I'm reading them correctly then at first sight the...

"panels facing different directions" - e.g. East, West ? An inverter with two MPPT inputs can take two separate strings of PV array, one string from east facing array, the second string from west-facing for example. Provided all the input specs are honoured of course and you have enough startup...

a bit of web searching will give you plenty to choose from one selected at random... https://www.deegesolar.co.uk/solar_batteries/

Binky is usually right... just for my own curiosity .... does your SE6000H look like this ? https://knowledge-center.solaredge.com/sites/kc/files/se-home-hub-single-phase-inverter-datasheet-eu.pdf or this ...

This thread might be useful too.... https://electricianforum.co.uk/threads/solaredge-with-battery-storage-retrofit.44369/

Not familiar with solaredge, but a bit of web searching suggests you need a storedge? https://knowledge-center.solaredge.com/sites/kc/files/residential_catalogue_eng_uk.pdf see p29/30 looks like can also use 48V batteries with this see p24...

You're welcome sjroberts, it's just my 2d worth. 6yrs payback sounds worthwhile on the surface of it. As other posters have commented it sounds like cheaper tariffs are possible, in which case it may make the payback time excessive. Sounds like you have the data you need to make an assessment...

Sounds like a good situation to be in :) The questions I would be asking myself in your situation would include:- i) How many kWh are being used for the 5h from 02.00, how much does the grid supply cost for those hours and, assuming a battery could supply it, what would the payback period for a...
