I am installing a multiplus II 2x120 inverter/charger in my RV. I was wondering if I can use solid strand 6/3(NMD) for my 120Volt side or does it have to be stranded 6/3

solid or stranded 6/3 wire for my Multiplus II
In general, solid conductors are best in a stationary situation (house). When subject to vibration, the copper work hardens and eventually fractures. This is why stranded -more flexible- conductors are better in an RV or boat. However, as long as the wires are very well supported it is possible to use solid conductors in an RV.
SOOW cord IMO. Way easier to work with. #6 is really big BTW , how big is your inverter? I have a 3K Multiplus and I ran all of my 110 stuff with 10-3 SOOW. Should handle 30A.
