I found both legs on my split phase for both my air conditioners were crossed. The diagram below shows what I mean: So for the 16 years my house has been built, one 120 volt leg of the split phase leg from each air conditioner goes into Air Conditioning Circuit Breaker 1; the other leg of the...

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...

Could not find the 1.25 times rule, also called the 80% rule in the 2023 NEC code. What is the source for the 1.25 rule for over current protection? Need to size a overcurrent protection 1.25 times the constant load. This could also be known as the 80% rule. I find sources on the internet...

How many tons and how many SEERs is this unit? Model: 24aba348a003001a Trying to figure out essential loads for a grid tied 8kw outback radian with battery a 10 kwh battery. Actually trying to see if this can be powered by the Radian. Not expecting more than an hour of runtime with the...

I want to order this for a project and am not sure what to search for’. The white/neutral wire goes in the square. Google reverse image search did not help.

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...

Do you really see earlier production by putting panels in series to exceed the charging threshold? I don't, but I'd like to hear your experiences. I thought I was getting a bit of watts doing this, but I’m not. For example panels set up 3S for a potential 66 volts to squeeze more watts early...

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 ran my water heater today off solar, and as many know, takes a lot of energy. Specifically took 1.28 kWh at 1602 watts at which is 48 minutes for my 6 gallon tank to get warm from a water temp of 60 degrees. This time seems in line with my 8800 BTU water tanks claim to heat 7.4 gallons an...

Anyone have a decent recommendation for a RV shore power 30 amp to 50 amp adapter? SOmething like this: More specifically a Female NEMA SS2-50R receptacle to a Make NEMA TT30P adapter. I have purchased two of the product above and both the internal connections on the 50 amp side, have had...

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...

What do you do when your one part you need for your project is delivered on the wrong side of the country by the post office? Not really humor but I’m waiting on a y adapter for parallel panels on my roof and the post office shows this delivered. When I looked at the tracking #, it shows...

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...

Really want to know if my wiring diagram at the bottom will work. This is in REference to @FilterGuy ’s Inverter DIsconnect with pre-charge in the resources at: https://diysolarforum.com/resources/inverter-disconnect-switch-with-precharge.60/ I m getting reday to build the 24 volt version...

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...

How do you hook the AC ground in the three pair cable for the AC out hardwire cord to your inverter? My AC ground has a #6 stud, but I don't see how to get an 8 AWG wire to fit that stud. I'm sure I'm missing something obvious. First time hardwiring an Inverter. I have a 3000 watt 24 volt...

What do Your Set Your Low Temperature Cutoff to for Lithium Batteries? Any reasoning to would be nice. I’m thinking of having the SCCs shutoff charging at 35, and the BMS shutoff charging at 32. I used to think this was an easy question with the battery spec sheet saying 32 F; however, the...

Input welcome. Have an overkill 8s 100 amp BMS that reads cell 1 and 2 as extremely low, but tests fine with a multimeter. I’ve replaced the ring terminals that measure them and same readings. This was just installed in my RV but had been used two months ago to pre charge for a top balance...

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...

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 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...

I installed my Victron Orion 24/12 70 amp DC to DC Converter and it sparks. Something is wrong with it. I was pretty surprised to see that has one post for both 24 volt and 12 volt ground. Sparks when a lead is added. I removed the ground leads to troubleshoot, and it still delivered 2.5...

What type of inverter would you use for 1500 watts constant draw for 8 hours? I find myself on my RV once this build is complete to enough battery power and solar production to do Level 1 EV charging. Probably not for 8 hours, but more like 4 hours. Never put much thought into an inverter for...

After waiting four months, I hooked my BMS to my batteries: THat matches really close to my readings of 3.30 per cell with a DMM.

My 30 volt 10 amp power supply from Dr. Meter lasted 2 months and now there‘s a component that rattles around inside. I started the return process from Amazon. It was outside the 30 day window, so I had to message the seller directly. This is a picture of the component that was rattling...

I hook my Aims Converter 120 VAC to 12/24 VDC to 4 Lithium 280 ah cells and the Lug sparks as I hook it to the terminal. Can buzz also if kept on. I’m sure this is not normal and see nothing in the manual about sparking. I am hooking this up as the instrucitons say powered off and connecting...

Looking to purchase open end ring terminals of one size: 1/4” open end ring terminals. It’s for an M6 stud which is loosely equivalent to 1/4”. This is a 6.3 mm size ring. I got these as a variety of sizes and am only using 1/4”. I can not for the life of me find them in one size, but only...

I am mixing Topband 3.2 Volt Cells with different capacities into a single 8S Battery. There's about a 6% difference in capacities in the cells. I wonder what will happen? -Three are capacity tested at about 24.7ah. They are the blue wrapper ones from BatteryPlus, now sold out. -Five are...

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...
