ISB Sola regulators
Some info and a question. First of all I have created a chart with the specs for the ISB Sola 4000 & 8000 compared to the Hughes 30 and 50 amp autoformers. Here it is https://www.mexicocaravans.com/IS...

The 50(male)/30 adapter connects one 50A hot to the 30A hot. The other 50A hot is not used. The RV is limited to 30A by it's 30A CB.
The 30/50 adapter connects connects the 30A hot to both 50A hots. This is a connection that does not trip the pedestal CB so it's not a short in that sense. It provides 120V everwhere in the RV with a total draw limit of 30A.
What happens with a 120V sola device is dependent on how and where it's installed. Hardwiring inside a 50A RV has potential issues when it's later plugged into a 120/240V 50A plug. The devil is in the details.
