12 Volt bed outlet - what can it safely power?

[SafetyGuy]

Found this after reading post #74 which has diagram of wiring similar to residential L1+L2=120+120 for 240 circuit one leg being out of phase with the other. =

The 2022 Ford Maverick’s factory 400W system uses a modified sine wave, split-phase inverter topology that outputs two 60V AC legs relative to the chassis ground. However, because the vehicle isolates the electrical system from "true earth" ground, this configuration cannot safely or effectively be wired into a standard residential split-phase (240V) panel. [1, 2]

Understanding the Factory System

• How it works: The 400W system shares 400W of total output across the in-cabin and truck bed outlets. It outputs 2 × 60V AC legs out-of-phase, combining to provide 120V AC. [1, 2]
• Limitations: The factory 400 Watt inverter frequently faults if connected to high-draw appliances, medical devices, or large-motor tools. It is also unsuited for safely back-feeding a home's power grid. [1, 2, 3]

Yep, the information provided by @BlueSpec1 looked like it answered many of your questions!

I will still need to sit down and labour through it all at a snails pace.

Interesting info was that sitting with engine running, it provides 400 watts of power, but driving I think it only provides 300 watts...

So, in other news, I went out and plugged our Ecoflow Wave 2 Li powerpack into the Maverick 120 volt plug. The inverter in the truck appears to be a modified syne wave type inverter.

The Ecoflow did not seem to want to accept power from the truck on my quick test. Good news is that the DC charge cord plugged into the 12 volt power port worked great, and I had my Ecoflow set to allow only up to 8 amps of DC power to stay under limits of the truck aystem.

Interesting development, but more research to be done to confirm this as fact.

I added this, as the OP, @Yellowjacket is looking for what can be powered by the available power in the truck...so we have circled back in this thread, at long last.

Have a good one,

Andy

Note: I believe that the 20amp fuse runs the 300/400 watt inverter because the inverter is split phase with the AC legs being out of phase with each other and will share the same steady dc amps. Line 2 polarity is inverted resulting in the 60v of each line accumulating to yield the 120v. If it wasn't split phase then more dc fluctuating current would be needed for same wattage limit.
Also if your ecoflow will accept two dc inputs you can supply a second dc input through a second 20 amp fuze to increase its charge rate with 8 or (?) amps on each dc input. It has been posted the dcdc is rated at 265 amps continuous (300+ amps) and battery is fused at 200 amps. @Yellowjacket might check into using a split phase inverter for possibly using smaller wire size (note the 400 OEM inverter uses 18 ga wire shown in post #74.)
