After not hearing anything again for another week(two weeks since final inspection passed), I called back my adviser. She basically said they dropped the ball on getting me invoiced. I still haven't seen an invoice, but the interconnection request went out to PGE about 20 minutes after I got off the phone with her.
So even though I'd received a response to my email request to get on the solar edge portal after they told me on the phone that they couldn't do it until PTO had been requested, it's been 6 days since that email response and nothing, so I called back support again today only to be told now that I have to wait for PTO to be granted, not just requested. She wouldn't even check.
So I guess I'm just going to keep calling back until I get someone who will put the request in.
