Mine always does a little boost. I think it's 2% but when voltage drops it bumps up by 10%.
30% would seem likely to cause other issues if you aren't careful. If you are drawing 20amp at the RV...you are now drawing around 27-30amp at the pedestal depending on the efficiency of the unit. Typical circuit breakers (particularly old worn out ones) don't like steady draws that high. You could probably run an air/con but if the battery charger or anything else kicks on, you are popping the breaker.
valhalla360,
That's an excellent point.
I've had a 15 amp breaker pop when running the roof air--input voltage was 100 unloaded. It did give me an hour of 100% duty cycle before it failed. Fortunately I had access to the breaker panel. It is the only time I've had a breaker trip when using the autoformer.
I did have one 30 amp breaker trip in the "old" section of a commercial campground in Regina, Sk. That was before I owned the autoformer. I did a work around by forcing the Magnun hybrid inverter charger to do "voltage support" by lowering the input amperage.
Doing that had the side effect of increasing the harvest from the solar panels. I do not recommend forcing voltage support. It may have damaged the Magnum.
