50 amp in a 30
If I plug into 30 amp service at the RV Park, what can I run. Obviously, I wouldn't attempt to run both a/c's, but if I can get by with one, the park would be convenient for us. Thanks.

Hi Valhala360,
That's a nice write up on hybrid inverter/chargers.
However, do please realize that it is not "voltage support" (a la autoformer).
It is possible to limit the incoming amperage. Since I'm 30 amp, I limit at 24. If I'm boondocking, I drop that to 12.
If load support is active and the batteries drop too low, then the shore power breaker will trip. DAMHIK.
After this summer, I'll be moving to a 7.2 KWH usable capacity battery bank.
In the days before I had load support, I would do double conversion--plugging in only the converter--and running the RV from a 2500 watt inverter, powered by the
875 amp-hour (3.2 kwh usable) battery bank.
Agreed, things get more complicated in order to really maximize the available power.
Even most inverter/chargers don't do load support and yes, voltage is a separate issue You really need to have a firm understanding of what you are trying to do and how your system operates to maximize the benefits.
With 7.2kwh usable battery (pretty darn large by most standards), drawing off the batteries for extended periods becomes much more practical as long as eventually, there is an opportunity to recharge. You could pull 500w for 14hr to boost for air/con during the day. Assuming it cools off at night and can send 750w of power back into the batteries, it's viable but you would have to be keeping close tabs on things.
