DIY solar power Shopping list

If you have done DIY projects before then this will be easy. Below you will find This is the list of items you need to create your own DIY solar powered energy supply:

DIY solar power controller

1500W, 24V MSW-Inverter DIY solar power controller

1500W, 24V pure sine wave Inverter

  • solar UPS controller (which is the funding goal of this project)
  • Power Inverter 12V or 24V with at least 1000W continuous power
  • Batteries that add up to 12V or 24V with a minimum capacity of 35AH
  • cables & connectors
  • 12V 35AH Sealed-Lead-Acid (SLA) Battery DIY solar power controller

    2x 12V 35AH Sealed-Lead-Acid (SLA) Battery

    Solar charge controller 12V or 24V with 6A

  • Solar panel with a nominal power rating of at least 200W

These are the items I recommend, the links will go to an actual store where you can simply order for door shipping. I do have tested five different 24V inverter but there are hundreds of models so there are a lot of very good alternatives out there. Also I have ordered at the below stores myself but I am not affiliated with them in any way.

Here is a link to a Power Inverter FAQ that might be able to answer further questions. There are two types of inverters: Modified Sine Wave (MSW) and Pure (or True) Sine Wave. Some appliances to not work well with MSW, you can read about it under the FAQ link.

The cost for the above items as of February 2015 are included in the brackets – they might have changed already. There are many solar kits sold out there but most of them come with a poor charge controller. A good solar charge controller is important to maintain the lifespan of the batteries. Don’t save money here. I am open for suggestions to improve this list or lower the cost. The calculation of the solar UPS is not final yet and also depend heavily on the amount of funded units: the more supporters the lower the price.
Some big hardware stores offer free home delivery on the necessary items.

Watch: UNplug compact power generator – portable solar energy

Here is a quick preview of the next generation UNplug unit. It will be a like Power plant in a toolbox – the new mobile power generator. Check out the corresponding video.

    Great idea. Good luck!

    Excellent Idea! The one thing every one worries about the most during a power outage is the refrigerator. I’ve been pondering a solar solution for years that didn’t require a massive investment. Glad to see someone else has pushed a great idea forward. And what a great hook “One Fridge off the Grid”.
    Divide and conquer solar power. Where can I get the T-shirt? Now if we could only get homeowners to properly vent their attics!

    Modified sine wave inverters shouldn’t be used on inductive motor loads like found in a fridge , rather use true sine wave as some motors will run hot or not at all with a square wave inverter

      Thank you for the comment. Efficiency is better (less waisted heat, about 15%) with true sine wave inverters but also the price is a lot higher. I have tested many fridges and running them with MSW (Modified sine wave) was never a problem.
      The shopping list is meant as a suggestion and I would be happy if I would receive suggestions of alternatives for 120V

    Marcus, I’m confused. How do you plug in the fridge to your system? Do I have to run a new electrical wire to connect it to your system?

    Some more details on not just how to buy the pieces but also how to hook them up would be greatly appreciated.

    Thanks.

      Thank you for the comment! You have two options: run a power cord to your fridge (this I what I did) or have an electrician wire it up to the circuit (in the breaker box) that goes to your fridge.

    It really comes down to what your local code requires.
    Ignore this, and if there is a fire, your insurance company will have an “out”!

      Thanks for mentioning this. Local code needs to be followed.

    I have looked for a controller for this type of thing, and this looks like a good idea.

    One capability I would like to see is battery-less operation. So, when the sun is out, the attached freezer(s) would run, and reach their set temperature.

    A small battery may be needed only to provide start-up current.

    Then, when the sun goes down, the freezer(s) shut off, and hold their cold until the next morning. The temperature of the freezer is used as a battery.

    Great! Now, please, create a home cooling system which runs entirely on DC (current) provided by solar panels on the roof. A simple system that provides more cool air as the sun gets warmer and shuts down as the sun sets.

    Hello, thank you for this great idea, and I hope to see you succeed in marketing these over time. Count me in for one, if someone doesn’t come out with something better. How long before we can buy one do you think without the UAL approval?

    Love to be a beta tester too

    Thanks great work!
