Solis Inverter - Alarm code 1030 GRID-INTF

Sycorax

So I'm new to all this stuff and have no comprehension of grids/voltages etc, so my issue is:

As the inverter is powering down of any evening, I get a notification of an alarm error code 1030 GRID-INTF. By the morning, when the sun comes up, the error has resolved itself and the inverter seems to chug along happily all day.

This has been happening since it was installed just about 3/4 weeks ago .

The installers came out today and replaced the whole inverter, but sure enough, this evening I got the same notification, same error.

I've dug around everywhere I can trying to find info as to what this means in laymans terms and what's to be done about it. 

I have found this, but it really doesn't mean anything to me or give me a resolution:

Any ideas as to what's causing it and how to fix it, or does this happen to everyone's inverter when it shuts up shop when the sun goes down?

The link talks about THD (Total Harmonic Distortion) so my best guess is that the inverter thinks the grid waveform is dirty.
Here's another article on the same fault, with more info:

There are more search hits but they tend to give the same info.

Thanks for this, when the installers came out they didn't check any of the cabling from the array or out to the grid.

So I'm wondering if any of them could be the culprit.

I appreciate the link, I'll forward it to them and get them to have another go at resolving the issue.
