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...

Tequila,
Are you saying the shore power source is not fused or has no circuit breaker? I can't see how adding an additional breaker--if there already is one would help.
Thanks for posting the chart--it is where I did the math from for the buck and boost percentages. So it is buck of -10% (135 volts), boost of +10% (110 volts) and additional boost of +20% (100 volts).
The buck is a calculation only. The boosts were checked by actual measurements, but under no load.
BTW the lowest voltage I've measured was 99 under no load and 97 under load from air conditioner. The Sola basic allow me to cool down my RV safely.
Based on the fact the 8000 does not have 2 hots, i see little reason to use it rather than a 4000. I have had voltage drop to 80 volts on one occasion.
