I have an idea, but I don't think it's very good - and I wonder about it's practicality.
But, perhaps, it might initiate other ideas?
Can this be solved using a contactor and hard-wired timer?
That is... have "power from the grid" coming in and power a contactor and 5-min timer before it gets to your house (and your solar system's feedback connection.)
Use that contactor, again, to block power going to your house (and your solar system's feedback connection.)
Use the hard-wired timer to kill the contactor every 5-mins.
When grid power is on - everything's connected (and you can send your feedback back onto the grid.)
-your connection to the grid will go down every 5 mins. But, if you have power from your solar system - you shouldn't even notice (theoretically) before the gird powers the contactor back on again
-I'm not sure how practical this part is. That is, how often will the contactors fail if they're "firing" every 5 minutes? Do you actually not notice anything - or will this actually cause your lights to dimly flicker every 5 minutes (can cause power issues to other sensitive things like computers or electronics.)
When grid power goes down - everything will swap over to your solar system - again, at this point, you won't notice. As well, your connection to the grid will actually still be connected at this moment.
However, when the 5-min timer goes off, there will be nothing to power it back on again - this is where your connection to the grid gets severed (automatically) and your solar power will then be the only thing powering your house.
Not sure if there's anything useful there or not.
Just a thought.
