I have finished my crate build: Originally a Crate Build: 600 wh, 24 Volt, 300 Watt Inverter, and put a second battery pack to make 1200 wh Goal was to continuously supply 250 watts of power which could get recharged simultaneously by 600 watts of panels. I will call that a success with a test...

I will be adding some removable panels to the side of the RV. These will be removed whenever I'm driving and will only be set up once parked. These will be South Facing panels, with the intent of when I use air conditioning in the fall and spring when the sun is lower to the ground, this will...

Not a solar stall directly, but I was having trouble figuring and "aesthetic" installation of a USB port on a short ceiling. I'd searched for weeks before deciding. Have been wanting to install a USB charging port in the kids bunk, and I've decided to tap into the light to avoid tearing a wall...

I did level 1 charging with my Tesla model 3 with my solar setup, and these are the results: 4.33 miles / hour charged 322 wh/mile from the ac inverter 367 wh/mile from the Batteries to cover AC losses AC draw from inverter while charging 1400 watts +/-2watts. AC Draw from inverter before...

I made thicker leads for my Bench Top Power supply, and this made a huge difference while charging the batteries. Went from 3.6 amps in Constant Voltage with the tiny terminals that came with the power supply to 10 amps in constant current mode for the 10 AWG wires. This should cut down charge...

I am testing running my 15K BTU on solar in my RV off a SAMLEX 3000 watt PST 24 volt model inverter and two 8S 280 ah Cells (560 ah total). Here are some stats: Watts From Battery: 1650 Watts From Inverter: 1470 I did this with the Micro Air Easy Start Micro Air 364...

I put together a couple of 25 ah 24 Volt 8S Packs and made my own busbars for this. I chose 1/8" X 3/4" 110 Copper bus bars. •https://www.ebay.com/itm/303841271273 These are rated for a little over 200 amps. Way more than these 25 ah cells will push. I'm deciding to learn how to make my own...

I made a case for my Daly 30 amp BMS out of popsicle Sticks. $1.05 at Walmart. I had the paint, wood glue, scrap lumber and 4 screws. I’m sure there’s a better way, that’s just the best way I could think of.

I have built and am testing a homemade USB Quick Charger 3.0. I'm using a charge socket, a solar panel and a converter. Want to do this without the battery, so I'm hoping the converter will work. Long story short, not sure this project works for a bunch of reasons. I know I'm not the first...

I'm getting close to turning on the switch for my 12 volt 1000 watt with 600 watts roof mounted and 400 watts ground mounted PV build. This is the 400 watt portion. It's: four 100 watt Lion Energy portable panels hooked in parallel, The panels are Hooked with Anderson Powerpoles a...

I put my RV away for the summer. Will take it out in October. Arizona is different and RV‘ing season is opposite of most of the country. I did enjoy putting the 1350 watts of panels on top.

I wonder how many of you check your portable array each time it’s set up. Every time I set my portable array up, I need to check it. For some reason, about 1/4 th the time, something is wrong. Could be as simple as a cable not hooked up to a recessed pin or wire loose. I have this array of 9...

I have ordered Eve 280 amp cells to make 24 volt batteries. I am planning on ordering one BMS for each 24 volt battery. I am looking at Overkill BMS 100 amps at 24 volts. I don't have either product yet, but am reviewing spec sheets for the build? My question is, the Eves are supposed to be...

Welcome comments on my diagram prior to assembling these 2 X 8S 214 volt total of 560 ah build for my RV. I am putting these in a slide out battery tray, so this limits how to place the cells. 8S will fit in the 24 1/4" Wide 24" tall picture, but once compression and material between cells is...

I have a grid tied Outback Radian that has been operational for three days now And I’m going to leave some notes In this thread. I have installed an off-grid 3 kW Inverter 2.5 kw panel and 13 kWh battery packl assembled out of cells, and I had considered doing this myself, but I honestly was...

This is an upgrade to 2.2 kw and 24 volt lithiums from my 1.3 kw V build with 4 GC2H FLA Batteries discussed here: https://diysolarforum.com/threads/my-rv-build-600-watt-roof-mounted-panels-and-400-watt-ground-mounted-panels.14212/ Batteries I have two Batteries, 24 volts with 8 Eve 280 cells...

I am in the process of upgrading from 12 volts to 24 volts, and my first step I finished yesterday about installing a 24 volt inverter and rearranging the four golf cart batteries to 4 S. I measured the am draw on my 12 volt appliances, and I was expecting some 24 volt to 12 volt conversion...

Wondering if I need to go from my 10 amp circuit breakers to 15 amp to match the Maximum Fuse Series Rating of 15 amps? I will have a set of three 100 watt panels in series with a circuit breaker. Optimum Amps is 5.7 optimum volts is 21.6 and shot circuit amps is 6.3 and optimum volts are 17.9...

What are you using for bus bars for systems in excess of 48 volts DC? 48 VDC max seems to be the magic number where companies like BlueSea cap out their lower amperage busbars. For my situation, I want to build a combiner box where each string of panels could be pushing 66 VDC. I had got Gang...

Have you noticed any panels on that are listed suspiciously for output setting off red flags? My understanding is there's a certain output per panel surface area that is not that does not vary all that much. some may be 18% efficient, and others may be 22% efficient, which is may put out 20%...

I made a series Cable for my 24 volt battery build. Fairly happy with the results. Tested good with a mulitmeter ohming it and then for a Open Circuit Voltage test and Short Circuit Voltage test: Boy, there's a bunch of details going from a 12 volt trailer system to a 24 volt trailer...

Has anyone converted a micro-inverter panel label to things like VMP,VOC,ISC, and IMP? Of course a spec sheet is the obvious answer, but a search of sunpower’s spec sheets shows nothing. I could do some back of the napkin math based off some measurements after purchase, but not sure how that...

No Longer For Sale Want to sell three left over 25 ah TopBand 3.2 Volt Cells from a project. These cells were top balanced and capacity tested at: -25.005 ah -24.122 ah -24.039 ah https://batteryhookup.com/products/new-3-2v-25ah-lifepo4-topband-navitas-prismatic?variant=40145310908578

I'm wondering what have you done for tilt panels when installing wiring on the roof? This will be my first time doing this so will take any tips. I'm thinking of having a couple of turns of 10 AWG wire when closed and that way it will just expand like a spring for the two or three feet when I...

I am trying to make legs for a portable panel and am looking for these legs and can’t find the device that allows different angles for the square tubing: I am going to make the leg itself out of 1/4” square tubing or 1/2” square tubing, but what I’m stuck on is what is the device called that...

GFCI Outlet Not Working on RV trailer The GFCI worked fine until I did my solar install. I have a GFCI outlet that is not supplying power to itself or any of the three outlets attached In my fifth wheel trailer. It stopped working on both my UL458 2000 watt inverter, and my 3000 watt inverter...

I am looking for a 1.75 inch outside diameter plastic junction to for a battery vent hose. Apparently the battery hose only comes in 1.75 inch inside diameter, while Lowe’s, Home Depot, Ace, Amazon, EBay and google do not carry any 1.75 inch OD plastic t junctions. Only 1.5 inch and 2 inch T...

Time for a new torque wrench!! What recommendations? The ones I get on Amazon and Autozone are not working out. Mostly, under-reading a value and stripping out bolts. For my solar installation, I'm looking at 1.5-12 NM (15-105 in/LBS). I would like a much broader range, but I'm sick of...

I don’t get crypto currency mining. The more I look at it, the more it seems like a giant pyramid scheme. I’ve fallen for a pyramid scheme before. This has all the signs of a pyramid scheme. To me there’s all these people buying into different crypto’s by producing equipment, and they plug it...

For those that have used metal on the sides of batteries for compression, what have you used successfully? I am doing a build where the extra 1/2" or 3/4" by using metal instead of plywood for compression on my lithium batteries would make the build so much easier. The metal that I have found...
