Re: off-grid - battery & winter 12V-generator?

Most larger solar generators
need at least 30 volts DC input for charging to get faster charging and
to keep the wire size from getting out of control so the simplest way is
to use a standard mains output gas generator and charge using the mains
input on the solar generator.

Agreed. I've wired industrially for up to 1000 Amps with 4/0 cable, and No. 
2 welding cable on home projects. Common tools and supplies are good to 30A, 
above that the connectors and crimpers become expensive and harder to find.

Anderson Powerpole connectors are common for DC because the connections 
don't have gender like pin & socket where power flows only one way, 
batteries both give and receive current, both sides of connectors may be 
live/hot. All connectors of the same current rating and color coding will 
mate together and are shrouded when unplugged. The color coding is for 
separation by voltage but it can be milled out of the housing if not needed.
