Any Cotek inverter experts?

I'm moving up to a 48v system. Today I received my Cotek SD3500-148 inverter from Invertersrus. Things are not going smoothly so far.

I'm wanting to hardwire, and the manual instructs me to remove 4 screws and "carefully" pull the AC panel out. Step 1:

Now, the manual says that the panel can be rotated 90° (toward me and down) to allow access to the internal hard-wire port. This picture is an extreme close-up of the removed panel. That green circuit board in the left-hand portion of the picture is attached to the panel I'm trying to remove.

.

If you look closely you'll see that the white wire is hanging up on the blue wire which makes it difficult to pull the panel out much. I don't want to force it. Has anyone dealt with this?

I wouldn't bother hardwiring if I didn't think I had to, but this inverter will be running everything, including a/c if possible. The rating of each of the standard outlets is 20a - which may work. However, if I could wire them in parallel (use 2 plugs into the standard outlets and wire parallel), I could skip this hardwire hassle. This sentence seems to say that -- Page 21: "Note: if input current over than limit current, please adopt choose to Outlet Adaptor with 2 sockets" Is that what it says??

I'm in contact with a local man who's fronting for their tech support, but I thought I'd pose it here just for fun. Nothing like a Taiwanese to English manual.
