1. That's a very impressive set-up, great job!

2. Prepper mindset

3. tell me how you plan to balance the batteries so that one low battery gets the charge it needs without overcharging the other batteries.

4. That truck can idle and supply his needs at a fraction of the gas consumption compared to the fuel consumption.
   He can power lights and fans in the shop to be able to work on vehicles during a long power outage which could prove to be rather valuable.

5. Reeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee

6. Amazing set up it's like i just watched my dream come true. in your vid. Never thought I'd see anyone do the dual alternator setup. That's what you call a true backup system. And it's diesel! Sweet!

7. ❤❤❤❤❤❤❤

8. With current configuration, can you jump start the engine from the rear (auxiliary) battery? Or, do you need to wire in another relay & switch?

9. It looks like at full power with both alternators and high idle your system can handle about 2.4KW

10. Thank you, sir, some of us could use the laughs. God bless you and yours.

11. Ray you need to get cool air flow to that battery and inverters. Heat is an issue. Great job looks very good.

12. Ray it look like the inverters work and you have the capacity to operate your shop or your home cool and why not make a video and you had fun making it work and if the power goes out you are ready. Have a Good day Ray

13. LOL Its like Rainman Ray After Dark.

14. I'm curious what size wire you're using to carry 150 amps

15. putting a solar panels on the top of the box might be a bad idea, it could get damaged, how about the top of the truck? i have a topper and wated to put one there, but i can not afford one

16. Wouldn't be getting much sleep knowing your truck sat outside unlocked, keys in and engine running…..

17. surely its a ar(a)gent escargot

18. Just remember, watts is volts x amps.
    Watts in will always = watts out, not counting conversion loss.
    So if you draw 1200w on the AC side, you're drawing 1200w on the DC side.
    That would convert to 10A on AC side, 100A on DC side.
    Don't get fooled as to what capacity those inverters say, they just are not realistic.

19. You should keep that heat gun and the kill-a-watt meter at hand in your tool box, for demonstration purposes.
    Nice setup. I'd like to have such too but not fixed to my car. I'd keep an inverter in my car for mobile power, and one in the home with a big battery. And I'd get a 0-gauge wire with quick-connect, for connecting them together. And a high-idle, of course.
    You should get a wireless voltage meter that you can take into the home. So if that inverter battery gets too low when in use, you'll know before it'll cut out, so you can start the truck.

20. Ray I built a similar system in my box truck (turned mobile repair) for shop power. It’s also equipped with a shore line with transfer switch. Hasn’t failed me yet, and I got a generator mounted as well that’s tied into the shore system.

21. Now that you built it Florida will never see another hurricane. Murphy's Law.

22. 33:02 – is that a wheel balancing machine?

23. Anyone know what setup Ray used for the high idle switch? My 07 Dodge Cummins has an automatic high idle when it's below 40ish degrees, but I'd like to be able to set a high idle manually now and then, and I really dig the setup Ray has for his high idle.

24. Although I don't own one, I'm kinda surprised the inverter's fan didn't keep running after powered off for a minute or two to cool off. (Unrelated: I have a heater that does this.)

25. Rainman Ray Mad Scientist

26. I am confusion. If his main goal was for the truck to provide electricity in a more discrete manner compared to a gasoline generator. Wouldn't it have made more sense for him to buy a quieter generator? These newer closed frame inverter generators are very very quiet and rather efficient. I can see it being nice to have power without having to tote around a generator, but he has got to have thousands upon thousands of dollars inside just his toolbox to make that system work. Wouldn't it have made more fiscal sense to buy one or two quiet inverter generators and a few more gas cans?

27. Ray, did you finally break down and get a Renogy LiFePo4 battery for the back? I did not see those other lead acid batteries you had before.

28. @rainman. I think that you made a thinking error regarding measuring the current. You had fhe meter set in voltage and not in amp there for it measures Volt. If you look at time 11:22 you see that clearly that it set DC Voltage and on the display it is showing mV.
    That being said it works great

29. Also, you could power your shop from it and still do business

30. I was worried you might overload your 120 v circuits with the 6000 watt inverter. Then I divided 6000/120 = 50 amps and I was worried you were pushing 50 amps through 15 amp wire. Then I divided 6000/12v=500 amps and realized there is no way you can get that much 12v current out of your two little alternators. You really don’t need the second inverter. Be careful, please and put a circuit breaker or two on your 120 v side. If you are not sure what you have, limit the 120v draw to 15 amps per outlet on the inverter. Those gang outlet strips can cause a fire and you can lose that beautiful truck.

    There are two types of 120v plugs. Learn the difference. A 20 amp plug has a notch on the side so it will not plug into a 15 amp outlet. Your power rail is all 15 amps outlets. I could not tell what type of outlets your inverters had.

31. Great video, shows it working. However something is off on the total amperage and voltage drop though so it seems like something is wrong. 8000W inverters should be good for 60A @120V AC which would equate to about 660A on the DC side. So with the 10-15A load you displayed in this videos that should be around 1200-1500W and the inverters shouldn't be breaking a sweat at all. a 200AH battery does not mean it can only produce 200A at any given time. The "AH" is the amp hour overall capacity over time meaning you could draw 200A for 1 hour, or 400A for 30 min, 50A for 4 hours or 1A for 200 hours etc etc… @ 24:40, proves you are at less than 30% total capacity of the 8000W and yet the inverters are screaming and there's crazy voltage drop so just be careful. The wiring looks like its about 10% the size you need to really use the full potential of those 8000W inverters, you don't want a fire. With the load you displayed in this video that is a fraction of what you will need to do much of anything in your house. One microwave and a fridge is more than in this video. Don't cause yourself a fire here, something seems off. Just my thought. Master electrician here.

32. That Truck is F_ING COOL DUDE….

33. That super long power bar may be some of your hold up. the single plug going from the power bar to your inverter would limit you (in theory) to 120v@15amps which is about 1800watts. Thats likely consumed by your heat gun alone. You might be better with 2 half length bars each plugged into separate plugs. That way you can draw whatever the inverter is capable of.
    I love battery, inverter, generator setups like this, especially when tinkered by people who also love what they do. Where you find your energy, I wish I knew. Keep it up Ray!

34. 32:35 The 200ah battery is an awesome addition to your truck/generator. My big question is do you know the difference between pure sign wave and modified sign wave? One is the same as the power coming from your wall, and one can kill a television, but do you know which one. I do. Please respond for the answer.

35. I love the self build Ray.. it's Cool.. and couldn't have had a better truck to build it within.

36. At Princess auto you can buy a Diesel generator for home

37. 😮this boggles my mind. It's a diesel powered 3bedroom house power supply

38. Says something when I didn't understand a word but still found it entertaining

39. THE SUN VISORS LOOK GOOD WITH THE 2 TONE LIGHTER COLOR, ! NO ?

40. Man I hope u don’t burn that truck up.

41. So you have built a 2500watt generator with your truck. At what cost vs a generator? Truck + fuel + inverters+ 2nd alternator+ wiring+ labor+ battery= ?😊

42. After draining down the rear battery with all the loads with the system isolated Ray tied the systems together and put the amp clamp on the positive lead of the rear battery. It was reading -70 amps. The (-) sign indicated the current was going into the battery to charge it. The front system was then supplying the inverter load plus charging current to the rear battery. When Ray put the amp clamp on the wire going to the rear system at the firewall he read around 130 amps. That would represent the inverter load and charging current. These readings were all what would be expected.

    My only concern about this auxiliary power system other than the cost and complexity is that if he ever decides to get rid of the truck or heaven forbid totals it then system probably goes with the truck. I would be looking at a whole house gen set myself. Also there is a hidden cost for fuel to drive all that weight around all the time. Of course it obviously provides great entertainment value for Ray as this is at least the third video he has made on the system.

43. Mr Ray you are very creative man 👍

44. I get the feeling that Ray will be the one who invents the Mr. Fusion device from Back to the Future.
