100 foot of pex painted black thin plastic coating. mirrors. 100 foot of pex in sand battery About 4 5-gal buckets of sand. covering pex pipe. HUGE amount of styrofoam broken up, making like bean bags that I now have on top and bottom for insulation. Recirculating pump pulling 50...

I have gotten to the point now that when I goto buy an appliance that I want to put a kilowatt meter on it and test it before I buy it. I prefer used because I know it has lasted this long, there is a good chance it will still work. I normally research the model before I buy so much...

After going thru a few famines I figured out that if I use the feast better I will have more for the famine. On a bright sunny day, I will put on large loads in the morning 7 AM - 10 AM so the battery is down to 30 % for that feast day, this allows me to run the dishwasher, or...

Cycle count is dependant on how well you treat the batteries, keeping them at a cool temp, staying within load specs makes the batteries last far far longer. I went with them as they are brand new, and at $100 KWH I believe the best deal around. But, you have to do your...

Also not charging the batteries all the way up I goto 4.1 instead of 4.2 extends battery life.

The amount of watts pulled depends on if you have it set on full blast or not...... Hotter days more power required. The most watts I find it pulls is when in dehumidify mode. I am very pleased with it as it is portable, and quiet and so much easier to install than a mini...

https://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries This article has been one of the best I have seen for real test data on different levels of discharge. It seems the lighter the work on the battery the longer the life. It is like the oldest light...

No, you don't have the picture.... I heat the sand to heat my feet inside with no smoke for hours... Or, I heat the sand and use heat retention to cook my food for hours. I do heat the water directly, but bring steam into the home is something I don't want to do..... I am...

I have done this. I have used my vacuum tub solar heater to heat water, then put into a thermos, kept the water hot for over 18 hours, I was amazed.

His beer can method of aligning solar cells is very entertaining ;-)

Anyhow I ended up buying this -> Runs off 110V, a small mini split. $400 for a mini split that only does AC, but portable..

At last, I built a wifi voltage monitor for these 32 V batteries. Took me a bit to get the voltage divider right but storing the data like a champ! Now I can put on loads based on voltage controlled by the raspberry pi. Woo hoo.

Wow..... It appears that Mini Splits run on 48V DC internally per this article. This could mean I could go DC to DC from 36 V to 48 V direct bypassing the 220V step up.... More research needed -> see https://expeditionportal.com/forum/threads/mini-split-ac-hacking.176704/

So yes they sell Mini Splits that run off direct DC -> https://www.hotspotenergy.com/DC-air-conditioner/.... Maybe I could contact Senville and ask if they have a board for this unit to allow it to run off DC......

I am still happy I made the purchase. The one battery I have hooked up is running my fridge and this computer with no issues, once I get my power strip flashed with new bios I will then add more loads based upon voltage, On cloudy days I want it to do nothing but minimal loads. I am...

About a year ago a friend of mine said he was going to replace his golf cart batteries. I directed him to Will's videos and he decided to get some lithium batteries. For him it was like going from listening to a radio to color TV, the change was dramatic and he said he was not...

Interesting...... I have a 12V, 24V, 36V systems... I noticed that after my 36 V system was charged, at 2 PM each day that I had tons extra energy that I was not using from the solar panels.... So, after much testing I went direct from the solar panels to my hot...

Yes, I have followed all his videos with great interest. Looking at his temps over 250 degrees in the morning, if nothing else he has created a solar powered cob over or crock pot if he was to put a pot of beans in they would be cooked ;-0 I have completed my most recent project which is...

I am in process of making my next sand battery. I want to heat it either by solar panels, or by burning trash / wood.... I am looking to figure out how to get that heat trapped into the sand with the rocket stove.

No, I never made it that far, I made several "free energy" devices and came to the conclusion I was putting too much $ in and getting zero energy gain out that I moved on to systems that give me energy every time like solar..... I have been working on looking at ceramic kilns, and I...

Perhaps we might want to branch off into multiple threads? I think I might create a new thread for wood powered sand battery, or thermal mass heat storage.....

Thanks for that tip.. https://www.homedepot.com/p/FAFCO-Papa-Bear-24-ft-Solar-Panel-Heating-Kit-for-Above-Ground-Swimming-Pools-10028/317267977?irgwc=1&cm_mmc=afl-ir-123201-456723-232098&clickid=VFpxTnzoTxyNWR1y-lxkAyyvUkAXciXhzXP2Xc0

We normally take what we have in industry and apply that to war. We took the combustion engine and made tanks, I think the next move in war will be AI drones into war. They will not be like the movies, they will wait for the perfect time then act. I believe that move will be...

I just bought 3 of these, now trying to find everything about them. https://batteryhookup.com/collections/module-madness/products/lg-chem-10s-36v-180ah-5-94kwh LG Electronics LiMM-C.F/LGE Model Name Vista 2.0 Cell Module Assembly Rated energy 5.94 KWh Contains 30 LG Chem N2.1 60ah cells I...

I have 2 mini splits, I have the Midea U which the owner of this board just did a video about, it is 15 seer, 10,000 btu, however the most it pulls is 450 watts, thus I can use a standard solar system to power it. The big advantage it has is it is portable, at any time I can move it...

I have been testing this by using a hot water heater combined with pex pipe to + pump to heat the sand. It is much better to use a restive coil combined with a solar panels..... I switched over to using the solar panels direct to my hot water heater coil, now I have free hot water...

Well.. I switched from having hot water heat the sand to just using a hot water heater element in the sand to heat about 5 five gal buckets of sand..... Well the temp is now staying between 140 to 153 deg F I have not had a clear sunny day yet it has been mostly cloudy days and...

I actually found on another tread here someone had trouble with the bms and it may of been that I did not pre-charge the inverter before I hooked it up and may of fried it. In that thread they show how to check the BMS to see if it is damaged. I did use a resister between the inverter...
