3000 watt Inverter

[rk06382]

Forget the air conditioner. I installed vent fans to air out my class A motorhome. I have a 3kw Inverter powered by six 12v 1,000ah Battle Born LiFePO4 batteries. I also have ten 100w of Solar panels.

What are you going to power your 3kw inverter from? The Maverick Hybrid does not have an alternator & it only has 1kwh battery. It would be dead in 20 minutes with a 3kw load.

Electrical power is not free.

I'm thinking of buying a small "Economy" travel trailer to pull behind my Maverick.

It has a 15 amp 120 VAC wall type air conditioner.

We plan to "boondock" half of the time.

I'd prefer not to haul around a portable generator, deal with gas cans, fire hazards, emissions, and noise.

The hybrid Mav is pretty quiet. Has great emissions controls. And a large gas tank.

I'm wondering if I could run air conditioning a few hours a day with an inverter from the Maverick?

Also, the tiny RV has no LP gas.
The stove, and the room heat, and water heater are all electric.

I would not need to run all at the same time. I'd be happy running one appliance at a time.

I know I could put a several battery bank and inverter in the trailer.
But why when I can start the hybrid mav and let it cycle?

What do you guys think?

Start with using the inverter (2000 or 3000 watt) attached to the Maverick and see how it goes? Then, for silence, down the road I could use the inverter with a battery bank inside the Rv. If desired.

Electrical power is not free.

The Hybrid has a 36 kW alternator built in.
Can make more power than anyone could use. It has 265 amps of DC power at ~ 14.5 to 15.6 volts. Limited only by how much gas it holds.

You just have to keep the key in the ignition all night.

Gas will burn a few minutes to 30 minutes per hour based on load.

So it can power an RV for days.

My real concern is how will an AC perform on an inverter?

My fear is this is a cheap air conditioner since it is a cheap RV. But I don't have a lot of money. Plus the Maverick is small-ish. So I'm sticking with a 2400 lb dry trailer.

Dealer just confirmed the cheap-o fridge is only 110v. What the hell good is that? The WHOLE POINT is to keep food fresh while TRAVELING.

Fridge is only 120 watts.
Wonder how it would do on the Maverick 400 watt bed outlet I have?

He will only need 3kw of the 94kw motor generator output. The ice would cycle on/off and keep the HVB SOC between 30-40%. After a time the ice would keep running to keep the HVB temp below a certain temp. In addition the 3kw inverter will not be running at max draw anyway most likely.

The "traction motor" is not spinning while parked.

While parked, about maximum generator output is ~32 kw. But I digress. It's usually a fraction of that. But well above a 3,000 watt RV need.

That's peak. With all appliances on which I will never do! 1500-1900'watts, I'm more than happy if I can get that.

I think this is about perfect.
Now I just gotta try in real life.

If Generator of Maverick puts 110'watt-hours into the battery in 2 minutes (charging 30% to 40%)

That works out to 3.3 kW continuous output at engine idle.

If it's more like 1 minute, then 6.6 kW.

The generator in hybrids is HUGE compared to any conventional vehicle.

If it were a 12-volt "alternator" like on an EcoBoost it would be a 3,000 Amp alternator apples to apples.

Pretty sure the hybrid Mac has a 200 amp fuse on the 12v side of the DCDC. Check DIY solar forum, Will Prowse has some very usable portable systems. And search, this has been discussed in this forum.

"The first law of thermodynamics (conservation of energy) states that energy cannot be created or destroyed, only transformed, while the second law states that every energy transfer results in some energy becoming unusable, typically as heat, and the system becoming more disordered. Power loss in a system is a direct manifestation of the second law, as some of the input energy is always converted into unusable heat or work due to the irreversibility of processes, making 100% efficiency impossible."​

Each time you convert from one form of energy to another, there is a loss aka friction.

I have a Samlex EVO-3012 3kw Pure Sine Inverter/Charger. It has a 85-90% efficiency. I had to add a small radiator fan to cool the Inverter/Charger. I power it with 0/4AWG copper cable with a 400A fuse. I did a test run of the A/C. The start up amperage surge was about 2,400 watts. After start up, it ramped down to 1,500 watts. After one hour the Inverter internal temperature was over 150F.

A gallon of gasoline contains approximately 120,476 BTU (British Thermal Units). This value can vary slightly depending on the specific gasoline blend and temperature, but 120,476 Btu/gal is a commonly used figure.​

​

If one converts 1 kWh of electricity directly into heat, the amount of energy released is 3,412 Btus. This conversion ratio of 3,412 Btus per kWh is known as the 'site' conversion ratio.​

Energy conversion is 80-90% efficient with a friction loss of heat. Inverting DC to AC will have heat by product.

Bottom line A/C is not for boondocking. Any mods to the Maverick Hybrid electrical system will void the warranty. The High-voltage (HV) battery is a deadly 450v.

Please let us know what works for you. & post pictures.

You clearly know a little about this.

I mostly wanted to know:
How did the inverter handle the high load such as a wall AC unit. (1500-1800 watts).

And how did the AC unit handle being on an inverter? Did it run normally?

I'm mostly interested in this for the peak 2 or 3 hours a day. When it's too hot for outdoor activity, and fans only are woefully, insufficient.

The Maverick HV battery is 220 VDC by the way. The AC voltages from the AC generators can be higher.

I don't plan to "modify" the truck, unless you call using a lot of DC power from it, "modification".

I'm only planning to possibly feed an inverter while the engine is running.

For 3 hours. 3pm to 6pm.
If it handles it.
I was expecting the inverter to get hot and I was expecting to put external cooling fans on the inverter.

Is that 6 12V 100Ah Battle Born?

I use 4 at home.

Yes. They also with cold weather heating wraps from Battle Born.

You need a 2000 watt generator. No inverter hooked to your 12V battery will work.

Hybrid electric Maverick is a totally different animal. 12vdc battery under back seat is charged by the 460vdc traction battery stepdown transformer to 12VDC but its protected by a massive 200a fuse. 3000watt inverter is connected in parallel to 12vdc battery, using its own inline fuse 200a & probably to be safe from accidently switching polarity, an pair of inline diodes 1 per cable. Probably needs 4/0 guage cable and some chunky ring terminals.

I'm actually looking at doing the same setup with my new Rove Lite travel trailer... Let me know how it goes, thanks!

I installed a 2000W inverter in my hybrid, it works beautifully. I ran a test ~1.7kW load continuously for over an hour with no issues. I don't think this helps OP if he has an ecoboost, though.

https://www.mavericktruckclub.com/f...able-inverter-installation.44646/post-1103981
The DC/DC step down is rated for 265A and fused at 300A, so that's a theoretical maximum of 3.7kW at ~14V. I would want to leave some headroom for everything else on the 12V bus, but you should be fine.

Note that you need to make sure you're on the correct side of the 12V battery fuse, because that is only 200A. Also make sure you're using the correct gauge wire, and add your own safety fuse obviously. I would not want to draw 3kW continuously just because of paranoia but it should be fine afaik.

Got the trailer and the inverter.

Inverter will run the 1300 watt microwave and 150 watt TV and 400 watt personal space heater.

It's winter. Have not yet tried the A/C.
Pretty confident it will turn on.
But my batteries only total 300 AH when topped off. Really close to 12v under that heavy load. (13.6v resting)

At 85% efficiency (I made that up I dont know what it really is) batteries would run the A/C a maximum of 2 hours. Then I'm left with a "dead" trailer.

One hour of A/C and my batteries will be 50% drained.

Probably won't use A/C from battery.
But... could I feed from the Maverick? Probably. But I'd have to be pretty desperate.

I have no idea why this thread just popped up in my MTC forum GUI/menu, but I feel I should delayed-chime in...

The anecdotal recommended max to pull off a hybrid 12V circuit (e.g., the battery under the rear seat) is 30A. Above that you can run into issues with the DC-DC high-voltage BMS.

12V x 30A = 360W, said and done.

I've been looking at an electrical design for my pop-up Oru camper with inverter for the single burner inductive cooktop, microwave, and 4gal Bosch water heater (and only running one of them at a time, while allowing smaller other stuff like TV and soundbar).

I want a 3kW inverter. But the only rational way to do that is with a battery system (320Ah in my case, 600W solar - 200W on the roof and 400W suitcase array - and a 30A DC-DC charger to pull from the alternator while the engine is running. You need a _lot_ more current from that than the stock Mav 12V system can provide (driving or idle). Add 30A 120AC for shore power and you've got kind of the minimal fully functional Mav camper system.

So for just a straight little inverter box plugged into the Mav battery, it's 360-400W. The same holds for the native AC outlets (and including the 12V battery tap) as a total system load.
