2kW Pro Power with EcoBoost

[12Lariat21]

Ran some more test with some power resistors.

10.2 ohms = 1100 watts @ 108.5 Volts 10.4 Amps
6.1 ohms = 1900 watts @ 105 Volts 17.4 Amps seemed to be able to maintain this load, only ran for 4 minutes due to the power resistors getting hot. (images associated with this test)

5.9 ohms = 2000 - 1900 watts @ 104 Volts 17.8-17.9 Amps the inverter tried to power this, but it would fault out on overload after about 5 seconds.

Loads are rated at 80% continuous just like a house breaker most likely

Oh I would totally understand that, and most if not all generator/inverter manufacturers advertise their output as peak, and they list the continuous usage. Ford on the other hand, has seen fit to advertise it at 2kW, 20A at 120V...no less

So it's more a disappointment in their handling/marketing of it.

And honestly it's a pretty crappy inverter to drop 16v at load, for the $995 MSRP they charge for it.

To me it's kind of like Dyno numbers.
For me that's what they are. Numbers.

I just want to be satisfied with how the truck performs on the road. In fact, I'll give some of the numbers back in trade for a more polished or refined experience.

In respect to ProPower Onboard, I purchased the Powerboost to power my RV as if I was on shore power. It passed that test with flying colors. I don't know how much headroom was left, by the numbers, but I'm happy. Especially considering it accomplished the task using one bank. That would indicate that I am free to upgrade to a 50A RV in the future. Although in my opinion, the kind of 50A RV that I would buy isn't a tow option for the Powerboost. (yet more numbers. In this case, Cargo Capacity lol)

I bet with more RPM's the voltage will be higher. You have to leave some head room so you don't have to high a voltage when going down the road.

The DC voltage of the alternator will fluctuate.

It would be nice if Ford listed the continuous and peak numbers for ProPower. I'm guessing that whatever is listed is actually the peak based on what some have posted, and run wattage is less. I haven't tested mine like you have, but the voltages you're seeing would be concerning to me.
