Frustrated and need advice/help

Edit: I contacted support and it appears my inverters were never set up properly. It looks like only one panel was producing so they're seeing if they can get this all fixed up remotely. Fingers crossed... wish I caught this sooner but had no idea.

Hi guys. I'm honestly a noob when it comes to solar but I don't think my system was installed correctly but at the same time I don't understand the numbers. I have a 6.9 KW system (I think that's the right term?) 16 400kw panels. Enphase system.

My CT wiring was messed up and they finally got that fixed so that the values adding up makes sense. however, I don't think the system is generating what it needs to. since Thanksgiving my system has only generated 22.5 kwh.

Now I am in Buffalo and I understand it's been cloudy and we've had snow, but does that seem low for the system?

When the solar company came to fix the wiring they were shocked. I only produced that much according to the app.

I just know nothing about it, but my past two electric bills have actually been higher than ever before and that's kind of frustrating. I also didn't realize national grid charges a fee based on the size of your system every month lol

I'm just looking for any guidance or advice at this point because I'm kind of thinking I wasted my money.
