Hi,
Max continuous on 30 amp is 24 amps or 2880 watts. I use the Magnum hybrid inverter remote to limit my connection to 24 amps.
I'm currently at a campground which has old and weak 30 amp. I'm having to use my sola basic autoformer to boost voltage. No load voltage is 113. Putting on the fridge 325 watts, two oil filled heaters 900 watts and water heater 1200 watts drops the voltage to 100. Using the autoformer boosts that to 117 when all the items are drawing power. While cooking breakfast (electrically) today the load support cut in, meaning I was drawing more than the 24 amp limit. I suspect that means that on the shore side of the autoformer that I was drawing 30 amps.
The connection "order" is shore power to autoformer to Magnum to RV.
Of course, lower voltage on resistance type heaters means less output.
30 amps x 100 volts = 3000 watts
I suppose if I do not wish to tax the shore power connection I should set the limit to 80% of 3000 or 2400 watts.
2400 / 117 = 20.5 amps less 5% for overhead from the sola basic or about 19.5 amps.
However, there is no "heating" happening at the shore power plug in, and no tripping of the shore power breaker, so I'll probably leave it at 24 amps.
I did have a reservation for a 50 amp site--but they gave it away to someone else. I'm not too happy with them for doing so.
Thank goodness I have the equipment to deal with lousy shore power!

If you only have 30amp, it might be a couple weeks to charge or longer as the house loads will eat up a greater percentage of a 30amp supply (which is more like 25amp for continuous).
