Has anyone been able to make a homemade version that works?

How does one verify the Del Mod V?

I am posting here to see if there is any interest in my 2006 Ford Escape Hybrid Battery. The Escape itself still runs & could be driven to your location. The vehicle has multiple problems at 350,000+ miles and it's time to retire it. As far as I know, the battery is still good so the resale is...

Thanks for your comment! I am however looking for info on sand batteries, not water.

Greetings! I am going to assemble my larger sand battery I posted about here: https://diysolarforum.com/threads/sand-battery-experement.67368/ I have made a few slight changes & have purchased a large metal barrel measuring 6' tall and a 4' diameter. Before I start assembling this large...

Here are my results with the panels flat. I however adjust them every month & I do not have shading. My guess is that I will have at least 5-6 hours per day in the winter.

I plan on heavy insulation!

This is what I need help with in my calculations. I have a total of at least ten 240W & 250W panels to use for this project. I'm not sure if I need to combine them and how many to use per element? My elements are rated at 2600W each.

My system will be stand-alone as well, completely separate from my main solar array.

Thanks for your input! I am in a very rural area with lots of free sand on my property. I am not interested in the water version, only the sand version.

You get presents & money under your pillow from them? Lol

I plan on eventually making the Tesla system my main one after it is working & I have a better idea of how much I need just to charge the Cybertruck.

Daytime is what I plan on. Arizona is ideal for it.

Good clarification questions! My average use: every other day or every few days, 100 to 200 mile round trip. I live in a remote area and have to drive a long ways to small towns. The Cybertruck would be a second vehicle and I would not be fully reliant on it. Occasionally: drive the full or...

You are correct, it may not. It will give me more time to get my array up for the charging station.

Thank you. This is the info I need. The max range of the Cybertruck to get it "empty" is about 500 miles. With my current lifestyle, I would at worst max out the miles only occasionally. On average, I would probably only need to charge it half-way to get it full.

Thank you! I can't use AC to help charge as I live totally off-grid. I have two MPP LV6048 inverter chargers. Do you think they would work well? I am confused about using batteries. Would it be considered a waste to use batteries to help charge a battery? I could understand using the...

1. I'm not sure. I heard there were 3 different charge rates. Using a standard 110V plug in charger would take days-I don't want that. I would like to be able to fully charge in a day or less. Not sure how many kwh/ day that would take. 2. Again, not sure. I have two LV 6048 6000w inverters I...

I am planning on getting Tesla's Cybertruck in the next 2 years. I would like to prepare a DIY home charging station for it now. I live in sunny Arizona. What would I need to be able to charge it at home off-grid? What size inverter? How many solar panels? What can I buy/make on my own & what...

Good idea. Now that I recall, I think the YouTube battery theory guy talked about it.

I live in Arizona's high desert! I'll just tip it over & it will blow away or stay.

I am about to start with my sand battery experiment. I plan on using it as a simple heat exchanger by blowing the heated air through metal pipe(s) into a room. Dimensions of the build will be 4x8x4 to start, bigger if needed. I've decided to bury standard stove-top heating elements like the...

I for one appreciate things explained out to simple terms! Stupid people like me need things explained on a low level. ??

Thanks for your suggestions! I was concerned about resistive wiring getting too hot. Is it easy to attach radiator baseboards to solar panels?

What would be the best way to heat the sand using solar - heat resistive wires dispersed throughout the storage container?

For my experiment, I was thinking of using separate pipes inserted into the heated sand and simply recirculate the air into my home using a fan. I also would try using a water pump, piping, and a radiator in a closed loop.

I've been interested in making my own sand battery for winter heating. I would use a medium sized approach - not as big as the video's and not as small as a bucket. I'm thinking of the equivalent of a 2500 gallon water storage tank. What would be a simple way to make solar resistive heating...

Greetings! I am wondering if I can add this generator to my off-grid solar system and how to do it. My system is: 48V using: ---1 MPP 6048 Hybrid inverter/charger ---3 EG4 48V 100A server rack batteries --- Approx 3000 watts solar during sunny days We have been having many cloudy days in a...

I just made this exact setup. Come late spring, I will be testing it!

Greeting again! I got all the panels lined up in the configurations suggested and am just about ready to attach everything. I have the proper blocking diodes on each positive end of all strings. I am now ready to attach all strings in parallel and power my system. Question 1: I have 14 sets...

Thanks!

Are these the kind you would suggest?

Greetings! Just ran across this article. It is about how researchers have been improving the Sodium Sulfur battery technology. They point to improved carbon electrodes making them 4 times better. Sodium sulfur batteries have been around for a while. Has anyone used them before? Is this...

I might be wrong, but the label says they are 340 watt panels. I see the 1500 comes from 1500 max DC volts.

I've always been taught that the abbreviation for voltage is E, which stands for electromotive force. I (capital "i") is the abbreviation for current.
