Solar panels and battery - any real world recommendations?

Sucks, are you getting any traction through the support line? I'll steer well clear of that update

I've attached an image from the 5th below where I had slightly less generation so more of the battery was used - it was down to 90% before charging over the course of the day. Fox reckons 0.1kWH for the day and Octopus reckons 6.7kWh. I don't understand how that's possible if I'm not anywhere near the minimum discharge for the battery.

Bit of an update of this - after a lot of chasing, Eco Renewables finally sent an engineer round who found that the CT clamp had been installed before the meter, plus there was an intermittent fault on the CT clamp cable. Both issues have now been fixed so things are working as expected. Eco Renewables were excellent pre-sale and during the installation but I have to say the aftersales has been poor so far.
Our export has now been correctly capped at 3.68kw but still waiting on getting our approvals etc so we can get our export tariff setup. This has taken much longer than I was expecting tbh, pretty sure we'd have got it sorted by now if I'd just done it myself.
Yeah before I deleted fb I was on the owners group and it seemed like the battery updates didn't have nearly so many issues as inverter updates.
I'm on 3020 for my 9.5kWh and it works perfectly now with much more relaxed cold temperature derating than the 3017 that shipped with the battery.
Very much seems to be a case of if you don't have any particular issues, don't update
Yeah, there are a few tall trees around the house.

Just one (smaller) inverter?
No wonder its cheaper as that reduces the complexity, and there isn't that much cost difference between inverters irrespective of size in most cases.
Also no mention of bird netting

Yep and not sure Hanchu is any good
Did you apply for G99? What grid export limit did the DNO give you?

yes i did the fast track g99 myself and was limited to 4.6kw export
I have updated my firmware once since getting my inverter battery, it's a gen 1 AC inverter, the firmware that was on it was well outdated, I'm sure it was the basic one that came on the hardware.
I must admit I was pretty hesitant to do that one.
The update failed twice but it didn't break anything, worked on the third time, I did that about 6 months ago and I don't think I'd ever risk it again.

Yeah same situation as me. I'm not doing it again once it's fixed.
Good Evening Solar Experts!
Install done yesterday and all went well, up and running in about five hours. I got my DNO letter today along MCS Certificate. Today was a good day for generation and I could see that the spare juice was being exported back to the grid. When I sent over all my details to Octopus for the Outgoing Octopus, it suggested it would be about 6 weeks to set up etc.
Not that this is a deal breaker but what happens to that excess going back to the grid for the next six weeks, is it essentially my free gift the to the Solar Gods until I am set up for export?

yes....
I have a Powerwall 3 (for which I have DNO approval and 5.5kw export limit) and I'm adding solar panels. The installer I decided to go with is saying that no G99 application is needed. But in the G99 regulations, I found that Section 5.2.2 states: "Where a Customer intends to modify an existing Generating Unit or add additional Generating Units, the Customer shall notify the DNO of the proposed changes."
Do you think it can be done without notifying the DNO, or do I need to wait for permission before installing the panels, or is it enough to send a notification after the panels are installed?

The section you found seems pretty clear.
The generating unit is the inverter not the solar panels so if you are not modifying it (by changing its output) or replacing it, I’m not sure what the issue is.
I agree with your installer, no G99 is required.
Think about from the DNO’s point of view, they don’t care how many solar panels you have, they care about how much energy you could put on the grid at any one time. They have given you permission to install a power wall with 5.5kw export limit. Absolutely nothing is changing in regards to the powerwall and its export limit.
