If you have a mortgage with Halifax or Lloyds you could get £1k cash back as well iirc, there is some info a page or so back.
Solar panels and battery - any real world recommendations?

9 weeks before the new inverter / panels were installed. Northern powergrid took the whole 45 working days allowed.
As others have said, go for the larger inverter if possible. They're a similar price, you'll already be doing a G99 anyway and It'll open up a higher charge/discharge rate if you ever get another battery, more MPPTs if you ever want more panels in the future and remove clipping on what you're putting in now.
Had my quote from green team one.
£14.4k for
21 x JA 450w panels (9.45 kw system)
Givenergy 8kW hybrid inverter gen 3
Givenergy gateway
4 x 3.4 kWh givenergy HV stackable batteries.

As mentioned in the above replies, I have heard GivEnergy are having some internal problems, leading to support issues.
I'd also be interested in why he was so dismissive of SigEnergy, I know some don't like the fact that they are a relatively young company expanding relatively quickly, which makes them weary.
He said they have seen a real change with givenergy in recent months and weeks in terms of support and that they seem to have turned a corner?
Regarding sigenergy, it was mostly based around there being a low element of risk due to chinese/former huawei links. But also the battery warranty limit of 8,000 cycles compared to unlimited cycles with tesla or givenergy.
Maybe I've misinterpreted whay he said, but they were the messages I took away from our conversation.
Originally I thought I would settle for a PW3 but after speaking to a few installers now, I like the idea of a more modular battery option that can be added to and expanded overtime in smaller increments.
EDIT: "Very dismissive" was poorly worded in my original post. I suppose cautious was probably a better term to use.

The software is also pretty good IMO and you can use intelligent flux in the summer which will be beneficial on a big system like that.
Consider this, 8000 cycles is 1 cycle a day for almost 22 years.
Unless you have a tiny battery and are also on a tariff like cosy, with multiple cheap slots you're unlikely to be cycling more than once a day.
Only time I cycle more than once a day is when we have free power, and to cycle the batteries twice requires a 3 hour free power session. That's with an 8 kW inverter and 29 kWh of storage.
Bottom line 8000 cycles and unlimited is pretty much the same thing in reality.

Sig don't have a 10kWh battery.
If it's the Sigen 10.0 batt then it's a 9.04kWh battery with an 8.76kWh usable capacity, always bare that in mind.
Also that Inverter is a tad too small for that amount of panels.

That's what I was told.
You can acquire one, lift off the battery controller at the top, add the battery and drop the controller back on.

Solis have screwed up my wireless dongle again. they pushed out an update which stopped it working. they are in contact with the dongle manufacturer but no ETA on a fix (last time took well over a month). they offered to sell me a new one for £50. not on imo as it's their screw up and the install is under warranty but apparently the wireless module not included.
what makes it worse is I am having to pay for my electric between 7am and 12pm every day.. (I had 5 hrs of free electricity so forced my battery to charge and run house of mains. whilst doing this solis pushed out the update so I can't change it back leaving me force charging my battery and running off mains for 5 hrs every day at full price and I am not at home for another 7 days to go in the attic and manually change.
it would make me question whether to get a solis inverter again in the future. this is the 3rd or 4th time it's happened now in 3 years.

Perhaps. However it's the one that came with it. Solis only started supplying their own afaik after I got mine. but yes. Solis do now supply their own dongle, in 2021 however this was the one , it was even the one solis used on their installation video at the time
TBH i don't understand why my system needs to be updated outside of me doing it. if my inverter can connect to my home network and my phone can access my home network why does it need to go through solis at all?
they system was working just fine 2 days ago.
