CT clamp fitted, tap change done (20 minutes!) So far so good. Just need some sun!

There is no CT clamp, I don't know why. Similarly there is no power meter, just an Emlite. I asked the installer to limit export to 3kW but although he set it on the inverter it had no effect as, in his words, I don't have any grid monitoring. Fox were supposed to be looking at it today. I ran the i...

All the Fox change really achieved was to get rid of the Meter Fault error. Now, between about 10am and 4pm we get continuous inverter reboots, initially after a GridVoltFault error. This is at 256V as shown on the inverter, despite the installer saying they had upped the limit above that.

Ha, the DNO will fix the problem 27th June. That is a year since I contacted them!

Wow, I emailed Fox UK and got this answer "This is a settings issue we have now changed the setting on your inverter and it is operating as it should be now however if you have any other problems it may be worth contacting your installer as some issue we won't be able to resolve them remotely l...

I suppose there is the Kaifa Smart meter, which was originally for import only. The installers are of the opinion is is related to the over voltage issues we have. But current voltages are just fine and still this Meter Fault. And the old inverter managed for 2+ months. Bit underwhelmed really. I tr...

Thanks for your reply. I don't see a CT clamp as you describe but there is an emlite meter which has been in place from the start ( install complete Feb 2024 but incorrect 5kW inverter fitted). It shows a solid red light. Back to the installer I go!

Well, the problem has changed, but not for the better. The inverter now just has a red exclaimation mark and the words 'Meter Fault'. The export meter has no red lights on, but is showing the lifetime generation figure. I've followed the instructions to turn AC then DC and wait 5 minutes but no chan...

Sadly, the issue continues. Once yesterday, but repeatedly today from roughly midday. What is worse, the voltages today are not high at all, certainly well below the upper limit set by the installer when they visited earlier this week.

The installer just called, they rang the DNO and said customer has lots of expensive kit, if this problem you have known about for months breaks anything it is going to cost you guys. I am now supposed to hear from them today. Which is nice as they haven't responded to my complaint yet and have 5 ho...

The installer attended today. Winced at the voltage level. Spent no more than five minutes configuring the inverter such that it is happy at higher voltages. Now all I need is some sun! Time to chase my complaint with the DNO, who have known about this for eight months and done nothing.

Installer due tomorrow. I am sure it is the over voltage problem. It ran at 254, 255 even 256 between 10am and 4pm today, where essentially the inverter was always restarting. But bizarrely it then ran at 258 even 259 quite happily. It is beyond me, the only difference is that by the time it was at ...

Yes DNO already logged the voltage for a week and concluded there was a problem. They said that they'd make a tap change but 8 months later...nothing. Hopefully the installer can tweak as you suggest.

Thanks for the quick reply. The A5 sized label on the side says G8, so I am not sure it is KH8...By pressing the fingerprint button on the front I can get this: 0 GridVoltFault 12/05/2024 12:08. This is exactly the time the error started today. Nothing more recent than this is logged. I think the 0 ...

First post, be gentle! We've an 8.6 kWp setup with Tesla PW2. Until recently we had a Fox 5 kW inverter, despite the installer saying an 8 kW would be installed. That was rectified last Wednesday, since which time I've seem some weird behavior. Everything is fine until the amount of solar generated ...
