Default Renogy "30A" or "40A" could melt the TM bargeman cord.

I didn't know that they even make a "30A", but that's too much current (and will damage the bargeman cord, usually melting at one of the connectors into the 7-way plug.

Do not exceed 20A, that size is probably alright.

Default Why three "100Ah" batteries?

A single battery pack built with 280-300Ah cells would need only one BMS, and would provide for simpler wiring.

Default Solar system with Shore cord plugged into 3KW inverter

Calrification:
I mean plugging the shore cord into the 3KW inverter as a susbstitute for shore power when boondocking.

Reasons:
1. A reasonable price on Amazon for LiTime Mini 100Ah unit with built-in BMS.
2. Started thinking 200 Ah would be adequate, then decided I want at least 300 Ah after talking to boondocking friends.

They advertise "up to 15000 cycles," I'd stop looking at that one right there.

The BMS apparently doesn't have bluetooth / cellphone ;programming and monitor control.

Bargmans are usually fused at 30A just as the TM main battery is and #10 wire is generally utilized.

Another thing to watch is having the LiPos going to an inverter, plugged into the shore power lead, supplying the TM Converter trying to charge the LiPos.
