Looking into running 1500W/3000W start Inverter

[tlhmav]

I have the Hybrid and am looking into running a 1500W/3000W start Inverter directly to battery to run what I need when camping and on the road.Have seen many threads saying it will fry a standard alternator,Local Ford tech says "should be fine" for whatever thats worth.Thanks for advice in advance for thoughts and Ideas.

Well you won't fry your alternator. You don't have one. The 12v battery is charged from the high voltage battery by way of a DC to DC voltage converter. With an IC vehicle you usually use the alternator output as a guide as to how big of a inverter you can use. A missing piece of information we don't have is the maximum output of the DC to DC voltage converter. I plan to install a 1KW pure sine wave inverter because I already have one. Someday I hope we can find out what the maximum size inverter we can use is based on data and not just opinion. (someday I hope to have a Maverick, 12 months and waiting)

Not going to happen if you power it off the 12v battery.

The 12V battery that comes with a hybrid is a motorcraft Part # BXT99RT4A. They don't spec the AH on it but the RC is 65 so we can back into that with the AH being somewhere between 30 to 35 AH. Best you will get is 12V x 35AH = 420 watts.

If you need more watts you'll need to either install a higher amp hour battery or tap off the DC to DC convertor. You'd have to look into specs of the DC to DC convertor to see what it can actually produce for wattage. I wouldn't tap directly off the high voltage battery pack system, that is dangerous to do.

I'd take minute and read this to know which wires and circuits to definitely not cut into according to Ford.

Ha! Ford tech didn't even pickup on no alternator(small town).Thank you for your knowledge,just gonna go for it and see what happens!

Is that the factory battery?Some people say will not work,Your video shows differently,Thanks

Thank you for the modifier's guide.

It is a relatively weak battery as it doesn't power a starter motor. What you are saying is true if you are just going to run the inverter off the battery. But with the vehicle turned on the DC to DC converter will constantly recharge the battery. That's why we need to know the output of the converter to determine the maximum inverter we can use. I plan to connect the inverter directly to the battery with the inverter remote switch connected to the Maverick "on" circuit.

@TheWizziard
Agree the critical point is DC to DC converter. It has to be at least at or above the Amps in the Prius version, which can support 1500W and by the looks the 12v battery in the Prius is slightly smaller.
There is a bunch more 12v power take off points available as options for this truck. That doesn’t exist in a Prius. Bed lights, 2 extra pugs near tailgate, 400w inverter, resistance heat strips etc.
I have seen other YouTube videos from the guy from my Prius car camping days, looking forward to his take on a Maverick Camping setup.

A 1500W inverter requires approximately 125 amps on the 12v side at full power. Using 4-AWG wires. This limits the locations that you can connect it to. Most people connect it directly to the battery using the shortest wires they can. The plugs near the tailgate are fused at only 20 amps.

It is the standard hybrid 12v battery. Picture below is from my Hybrid and it is a 45AH battery as he states in the video.

I'm not sure why some people say it won't work because he clearly shows that it does.

I am keeping an eye out for a better sale price than the current $199 on that unit ALFFAA 1500W Inverter

I love that in the hybrid it fits perfectly under the seat and all that needs to be done to use it is lift the seat, attach the jumpers and power the unit on. I also like both the 12V in and 120V out displays including the amperage on the 120V.

When wiring it up be sure to use 4/0 wire as recommended here: Recommended Inverter Cable, Breaker & Fuse Sizing

Also note that 4/0 AWG wire is bigger and not the same as 4 AWG wire: WIRE SIZE, AWG AND FUNNY NUMBERS

12V x 35AH = 420 watt hours, not watts. The battery has 470 CCA and 12V x 470 A = 5640 watts. Obviously that can't be sustained for long, but the batter can put the sustained 1500 watts is only 125 amps and with a 1500 watt inverter it's unlikely he'll be hitting the max the whole time. I don't know how much charging capability the Maverick has, but a 1500 watt continuous inverter sounds like it has a good chance of working fine.

Since someone is going forward with this idea, I will share how I think the Prius camping crowd gets away with 1500w inverter setup with only a 100A DC to DC.
It 100A @ 14.8v = 1480W just below 1500W but the battery itself can supply the extra 20A for a short but useful few minutes.
Second, goal is to pick tools, microwaves and such that clearly are 120v 10A and below. So not to stress system running at 1500W. Self limits to run at 1200W.
I am surprised the Mavericks DC to DC amp rating hasn’t leaked yet ( it’s being guarded likely for this reason )
Two takes on why, first best case it’s from the F150 parts bin and not C2 based hybrids. Second, they ran the math closely and figured they can undersize it like they did with the batteries.

Just ran test for two hours 1400 Watts all acc's off on truck battery stayed about12-14.4 volts Ice kicked in a few times but better than expected,Think I'm good to go!
