It was a great run… I’ve had 5 days with this random craziness, cant reach signature solar

Have any of you seen something like this? It has done it during the day with 99% batteries, and 10,000-12,000w of solar

Its done it with no solar at night, with 90% battery

No detected patterns. Random

Any advice from you guys?

That is some crazy sh!t.
 
Maybe I cant see it good. Looks like alot off wires coming out of the load terminals, Are you getting any arcing? what size wire?

Looking at your past post, are you still running early 0E0E firmware?

Maybe your grid is flake?

I see you stayed on early firmware because you need zero grid feedback.

You now have the option to enable offgrid mode. Go to monitor website and click

No matter what solution you were trying you should have cut the Inverter power to the house immediately!
Once that is done you can flip off all the breakers except for a Kitchen plug and then plug in an incandescent light fixture to trouble shoot the problem.
That kind of thing will kill every AC and Fridge compressor in your house or at the very least shorten their operational life by years!

Shut the thing down until you get a tech on the phone tomorrow morning.

He has the grid relay bypassed for now (by enabling "offgrid mode"). What's causing the relays to glitch I have no idea.

Very strange.

What should one have on one's 18kpv so it runs as it should with ZERO grid feedback using pv's first, then batteries then the grid? I suppose SS will get me where I need to be come commissioning time.

Btw, I watched your video on the eg4 battery racks. I wonder how many times it's been redesigned at this point. I guess at least 5.

Will you need grid assist
Will you be feeding your main panel or setting up a critical load panel?

Micro Grid is for connecting your generator to the grid ports if you dont have grid available.

But if you have a generator tied to your generator port. It will not turn the generator on as long as Grid power is on. I hope this helps

Hello @Markus_EG4 will the 18k auto start the GEN when in micro grid mode connected to grid side
