Experienced something yesterday with my new Reflection fifth wheel that took me by surprise. After several days without sun, I hooked up my generator to replenish my batteries, and tried to turn on my 15K BTU Furrion AC...I have used this Eveready 3000W before with my previous Coleman Mach 15K without incident. This time it overloaded and failed to start the AC.
Is it because the converter was drawing so much power to charge the batteries? I didn't record the numbers but the Victron shunt was showing a pretty good charge rate at first.
Ironically, these issues will go away shortly as I had just ordered a SoftStartUp...now my question is will this AC start on a Honda 2200? Am I correct in my assumption about the converter using too much power early in the battery charging process? Is the Furrion AC more power hungry than the Coleman or Dometic? I am really hoping to be able to use a Honda 2200!
I’ll do a full article on your question this week, but your assumption about the converter/charger is drawing too much additional amperage is probably correct. My Renogy 3000 inverter has a 80-amp Lithium charger that draws around 9 or 10 amps at 120-volts AC. That up to 1,200 watts of your generator powered needed just to fast-charge your Lithium batteries.
My Mastervolt Hybrid Inverter will fast-charge the 400Ah Lithium battery at 230 amps, which takes around 25 amperes at 120 volts if I don’t limit shore power current!
This is definitely starting to come into focus...so am I correct in assuming that I could gain normal usage of the RV with the generator by switching the battery disconnect, allowing the converter to provide power to everything, and enough amperage for the AC to start?

Most likely, yes…
