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.

Back in the day when pianotuna started posting about the Sola device which had both buck and boost capability I wanted one for my 50A RV but that was not available.

I think pianotuna got one with some skullduggery (just kidding) and it's served him well for 30A. If the device was available in the US/Canada I suspect there would be more posts.

One of the Canadian members kindly offered to transport one for me from Mexico. It was kind of he and his wife to do so.

Tequila,

80 x 120% ~= 96 volts. I guess at that voltage one is pretty much hooped. That leaves generator for large loads and solar for low loads.
