Hello daveg, some generation curves from easypv you may find interesting, 2x 4.6kW inverters, no shading applied for these. The dips in generation are cloud cover presumably. Colour coding is green=battery, blue is self consumption, red = export Over 6kw from approx. 11am til 2pm, peaking...

OK little bit of free time again at last... Just posting an example schematic for a 2x inverter E-W setup, using a solix 4.6kw for east and one for west roofs (4.6kW is picked somewhat arbitrarily as I had the details to hand) the startup is 120V for the worst case string of 4 panels...

IMHO look for one with i) decent battery discharge rates, e.g. around 5kW ii) at least 6kw AC output iii) string voltage dc input which will accommodate your solar panels Inverters which come to mind Solis Givenergy myenergi solax solaredge enphase Suppliers which come to mind Solarsparky...

Thanks for the suggestion Badger

Thanks John, I was curious as I'm getting comments from installers about not placing batteries in direct sunlight, which in my circumstances is making it a bit tricky to locate them.

Cool, glad I've been useful for once! Suggest you take a look at easypv, it's free and very handy for trying different options out. Pvgis is another option. There are a few posts on the forum about two hybrids connected by an ethernet cable, it is possible in some cases, depends on the...

No worries, guess you need to decide between tp58 and tp30 options then...

Presume your inverter has 2 x MPPTs, East side into one and West into the other? You're trying to stay within the overall dc input watts from PV? You'll have a max volts dc input spec for each mppt though, if you're at the max inverter limit with 8:8 then sounds like you would be exceeding the...

spec says Euro efficiency for this is 97% spec says battery charge efficiency 97%, and battery discharge efficiency 97% ? it can output 7500W AC Is the installer proposing leaving the X1 G4 in place, so using the hybrid inverter as a PV inverter only? Guessing they would be looking at a solax...

Which model of inverter do you have? What's the spec for the panels?

Have you contacted Fogstar about this to see what they think ?

Hi, Nige are you on-grid or off-grid ? The Givenergy AIO system is sold as being an automatic switchover system if that's what you're looking for e.g. https://midsummerwholesale.co.uk/buy/giv-energy/giv-aio-gateway-bundle not cheap though and with 2kWp of PV I suspect you might struggle to...

I'm also non-electrician! The only thing I've ever seen that looks like this is a hoar frost which I once saw formed on the inner roof of a tent, would seem extremely unlikely to me though given electrics usually generate some heat and also you don't mention any refrigeration. best of luck...

Thanks folks, I see your point about fire resistant backing / mounting board one of the companies providing quotes I've received mentioned in passing that 'there were some regs on wooden sheds', I shall make a note to follow that up with them if I pursue their quote Hi John, how could I forget...

Thanks wgoldie, that makes sense enjoy!

Hi folks, wonder if anyone here knows the answer to this please? Are there any restrictions I should be aware of regarding installation of pc inverter and or battery inside a wooden shed. I'm not intending to do the work myself, just working through feasibility of where I can put various...

Congrats to you! Well done! Must be very satisfying to see that effort come to fruition. I'm intrigued how the addition of DIY battery to your existing system works regarding MCS and elec company export payments...

Thanks binky, yes taking the 'max out the roof' approach is proving a bit awkward! My thoughts were 2 smaller string inverters with an AC coupled hybrid inverter for battery, e.g. givenergy AIO or cough tesla powerwall. Not a cheap system, payback about 10yrs. Is that what you were saying...

Received a quote for an east west 8.7kWp system. Supplier charges an amount for dno Gxx paperwork, which seems reasonable in principle, but it got me thinking whether Dno would comment in advance of likelihood of accepting a submission and its level of grid export, a bit like a lender...

Simple solis only question. One solis 6kw string inverter or two smaller ones for an East-west system? Background... Quote for East West system West roof 10 panels 4.35kWp maybe 9panels East roof 10 panels 4.35kWp Roof ridge line points about 10deg towards East of due South. 29deg pitch...
