Heavy Duty 1500 watt Solar Generator Build (coming soon)

Lots of people tell me they want to build a much more powerful solar generator than my suitcase style portable solar generator for their needs but still don’t want to pay $1000 for a store bought one with solar panels. I’ve been telling them just to scale everything up but now I want to build one myself and show the results, so that everyone can build one and follow my lead or learn from my mistakes. It will still be portable but meant to be wheeled around rather than be carried.

I hope this coming guide will show you how to build a 1500 watt solar generator that is capable of running a circular saw, high power drill, refrigerators, many lights and other heavy duty items you may need to help your family survive a grid down situation build a off grid cabin or house. Heck farmers even could use this that have to mend fences too far away to run extension cords.

Goals for the Heavy Duty Solar Generator:

Power real tools and higher wattage appliances in real life situations, be easy to move etc.

  • Circular Saws
  • Full Size Refrigerators
  • CPAP Machines
  • High Power Drills
  • Air Conditioners
  • Lots of lights
  • Much More

Main Heavy Duty Solar Generator components

  • Wheeled Toolbox
  • Deep Cycle Battery
  • 1500 watt inverter
  • 75 watt solar panel
  • charge controller
  • AC Charger to keep it all charged and ready
  • USB outlets are great for small devices like phones
  • Battery Level monitor

 

Stuff I need to buy:

I have an 1500 watt Sunforce Pure Sine Wave inverter than came out of an RV I plan to use for this build

I’m thinking 1 75 watt solar panel or 2 50 watt panels that fold.

    With the group 24 battery whats the AH your looking at? Also, im a big one with weight, portability, watt output and charge time.

  2. I haven’t started putting it together but I have all the components except the box / container to put it in. I’m pretty picky but may have to just pull the trigger. I got a big AGM battery. Group 24 I think. Not as big as you! But the construction is really the same. Weight is a big factor with this bigger ones. Wheels are mandatory in my opinion to save my back!

    Have you started this project yet? I just got done building your smaller version (email me and i will send the video (mjwolf23@yahoo.com)). My next project is building a 250~375AH, 3000w generator. Suggestion?

    This is so awesome. I can’t wait to try this. I think this would be extremely valuable for emergency use…

  5. Matthew says:

    I figured the fat max would work the best since the bottom would be the batteries, the middle would be the outlets, then the tops for foldable panels or extra stuff.

  6. Hi Matthew, that’s rad you’re helping out your dad. To be honest I haven’t figured out exactly how I want to house the unit. I’ve see the FatMax at Home Depot an it is prices right but opens bigger than I want. Still on the hunt actually. Husky has some really tough wheeled tool boxes but I haven’t settled on which one yet. I’m being picky though, I know many will work.

    I’m building your smaller unit now to see how long it can run a CPAP machine for my dad. one day I’ll build something this big, but I thought the Stanley 020800R FatMax 4-in1 Mobile Work Station (amazon) would work out better. what are your views?
