Electrician threw me a curveball

I was all set to have my solarc 15 wired recently. Had Green Lantern drop line diagram based off the standard wiring diagram attached below from solark. Basically pulling off with the line side tap going through the inverter using the pass through 200 amp feature then back to the main panel. Green Lancer called the main panel a critical loads panel, not sure if that it was an accident due to soon other changes I'd made don't know if they forgot to take that off. Anyway electrician said you can't do that anymore. Says you lose the Nema rating on the existing main service. If you do anything to the bussing it’s not rated anymore. IE: tap ahead of the main breaker. Things have changed in the last 5 years he says. I thought the whole point of the tune of the amp past through on the select 15 was to be able to feed your main panel and such your whole house?

The electrician is correct. That's a combination meter/main panel.
Those are factory bus bars, and are not able to be field altered, without losing the UL listing.

You need a separate meter, not a meter/main. The easiest solution is to add a new breaker panel and move all your circuits to that.

Okay. Thank you for confirming. So in that case he is recommending putting a buss block on the Bussbar below breaker , go to the inverter and back to the critical load panel. Move all critical loads to the new panel. Would this be Optimum with the solark 15 in my scenario? This is a grid tide system with no batteries as of yet. Batteries in the next year or so.... all the manual labor I'm good for, when it comes to the nitty gritty of electrical code not my specialty. You guys are saying with a new panel though I can just move everything over to it and leave the old one as a skeleton

That would be the best option.

Thank you. I appreciate it everybody

Sorry, thought I was done. Quick question. In this scenario with a buss block added below the main breaker in my meter/panel combo and the power being sent to the solark grid in terminal then passing through to the new panel above the new 200A breaker, does this run afoul of the 120 rule in any way? Is this still considered a load side tap for municipality purposes?

If there are still other loads in the original panel then yes. You'll need to move everything over.

Moving everything it is then! Thanks again
