Yes, DC coupled Gen 2 has 5kW AC output power, so if you have more than that input from PV input (ignoring the efficiency) it will just dissipate as heat. How much of the 5kW goes to the house depends on the demand from the house and your export preference. You will save more money from PV by...

Right, that's why it wasn't making sense to me! Thanks

Which direction is the 'best shed roof' facing? It sounds restricted by trees so you should do a shading assessment too. If you have space it sounds like a ground mounted array would work better from the info you've advised.

Should there only be one black lead connected to middle battery, like on the red leads, or am I misunderstanding the daisy chain?

You're welcome Iceandsolar Option1: 12 x IQ7PLUS-72-2-INT (Enphase Energy Inc.) microinverters are generally a more expensive way to provide PV inverter (DC from PV to AC) IQ7+ is £140 ea. wholesale You might save some money by considering a DC coupled inverter such as the Gen 3 Giv 5kW, which...

Also, to help you decide, you'll find it helpful to know your present elec consumption per annum. [Edit: so you can see what proportion you'll save via PV. Hopefully included in your quotes though?]

Hi NC, welcome There's a few similar threads like this on the forum presently, suggest casting your eyes over those, to see if they help answer your queries and if not feed any remaining into this thread... What kWp of panels are we looking at here? Happy to help out, but to save repetition...

Uneducated guess: Presumably load restrictions are how many amps the fuse is in your meter cupboard, 60/80/100A, which is the upper limit on input to house, then internally how many amps the inverter can handle to supply battery and the total of how much different appliances use?

Check the situation wrt VAT, IIRC no VAT if some solar PV is included

(oops) Hi Ronny 1 perhaps work out from property details from estate agent. To start with assume 30deg roof pitch and do some trigonometry 6 free PV generation estimation tool

Hi there, some queries on my part -Why the microinverters in first two quotes but not the third? Microinverters are often used to combat shading problems. -What shading factor has been indicated for all three quotes? -Any reason for no west-facing panels? -Roof is 35deg pitch with respect to...

Hello RonnieUK, welcome to the forum. Questions are probably best asked in the solar PV forum, you'll find lots of useful questions and answers there which will help you. Suggest you make a new thread there. I'll do the easy bits here: For Solar PV, there are some things you need to find out...

Sounds good! oh my, is that another 15kWh?

Well done for solving it, and satisfyingly little spend too. Now the fog has cleared you can enjoy at leisure ;-) Sorry for the bad battery related pun, I couldn't resist. Will be interesting to hear how you get on with the fogstars if you have time to post.

Sunamp Thermino might be worth a look for hot water needs.

Also, not sure givenergy aio is released yet? https://www.givenergy.co.uk/products#giv-all-in-one Will be interesting to see final spec and system. Are they still British owned?

Another thumbs up for easy-pv. It's not clever enough yet to simulate charging battery overnight from economy7 though. also pvgis worth a look

Yes, recommend get 3 quotes with site visit. I had one quote recently that claimed the two sides of the roof were different sizes, from using Google maps, didn't seem to understand that the satellite wasn't directly overhead so the appearance on each half wouldn't be the same!

Hi MikeJ, for 48V battery Pylontech are popular, they interface with lots of different inverter makes. There are often several power related things quoted on inverter datasheets. The maximum PV power input, it's output to the AC side and to the grid (3.6kW / 16A limit), and the draw capacity...

wot no tentacles! serious failure in the sales and marketing dept. there enjoy :)
