Assuming the current was running at about 8 (conservative based upon your earlier reading) that would mean the total power would be about 4200w on your 3.6kw system, the same power output it dropped out before. Does it ever drop out at low generation times?

Is it possibly because his system is going over 16amps ??

Every event logged by the inverter has a numerical code for which there is an explanation in the manual.

From sunny explorer log in as installer and use the export option to export the event log as a CSV file.

You can then post the file or error numbers.

Hi
Just exported all the event date and the only codes are:
1 - Incoming
1 - Outgoing
10223 - Time Interval expired
10010 - Restart diagnosis system
No other codes.
The high voltages today did not coincide with high generation situations; cloudy low power generation just the voltage jumped from 260 to 320 and 160 to 220.
thanks again

what are you using to export the event data?

Sunny explorer?

If so, I'd double check you've got the date range sorted out properly to give you eg the last month, otherwise as standard it only gives you the error log from today.

You need to use the calendar bits top right, and highlight the date range you want, then check it's taken properly.

Hi Gavin
I used the date range from 3 Mar to 14 Apr.

Hi
Just checked the country setting on Sunny Explorer and it says "special setting" is this normal or should it say G83 ?
Do I have to use a different login to check the exact country setting ?
I believe the country setting can be seen on the inverter panel during start up. Where exactly on the panel is this information shown.
Thanks again for all the advice.
Cheers

Its on the bottom of the panel in the message area.

Sunny explorer, Under settings/grid monitoring mine says Country standard G83/1

 

[Earthstore]

If the inverter has not been set for the UK, which sounds like the case here, the installer will have to now get a grid guard code from SMA to alter the settings, as the inverter has now been running.
This is not uncommon, as many installers believe that all inverters are just plug and play and come already set up for the UK.
I hope this helps.

Hi wstevew
Interesting, under the same menu mine says "special setting". Do you log on to Sunny Explorer as user or something else? I mentioned this to the installers so they are going to check.
Thanks fro your help.

[wstevew]

Yes that was as a user.

Earthstore is right they haven't set it up right. Quite common as they have to set the dials behind the black panel correctly. After 10hours it locks the setting and it can only be change with sunny explorer as installer and they.must have a grid guard code from SMA.

Hi All
Thanks for all your responses, system seems to be cured no after changing the country setting to G83/1. Last four days have seen 24 KWh a day generated so I`m quite happy with that.

Seems the installers have never had to change a country setting before.

Once again thanks for your help.

Cheers

Seems the installers have never had to change a country setting before.

that doesn't bode well, being as all sunny boy HF and TL inverters need the country code setting on installation.
