Someone was having fun with Photoshop for this ad.

The group here is a wealth of knowledge but they need accurate input from you. More information is better then less. 1. PLEASE post a picture of the label or data on your solar panel. In a lot of cases saying you have a 300 watt 12v panel is not enough information. 2. Again a picture of your...

For those that live in places like me that gets snow, I thought I would share how I clean the snow off of mine. Buy yourself a Snow Brum( link posted below) . Take the handle comes off and it has the same thread as a paint roller so I just attached mine to an telescoping paint roller pole you...

Although I am retired I get called in for special projects from time to time so while I was in the shop I decided to cut some stuff for my solar project. I had access to 1/8" brass so 10 mins to draw it up and 11 mins of cut time and I have spare buss bars. While I was at it I drew up some...

I built the panel racks and ran all the wiring at the end of Sept 2022. I got the system running the beginning of Oct 2022. 8 Axitec 290 watt panels, 6 Canadian Solar 340 watt panels, 2 Growatt 24V SPF 3000TL LVM - 3kW . Yes they are over paneled. It didn't take long to figure out that I needed...

I received 8pc PWOD CATL 3.2V 310Ah grade A lifepo4 batteries from Aliexpress a few days ago. I placed the order April 13th. They showed up 1 month late but they got here. From the pics below you can see the box/packaging was in great shape. The batteries were packed individually. and I have...

I noticed in Will's latest video he was wondering if one battery was warmer then the other. A simple cheap tool that is good in any DYI tool box is a Infrared Laser Temp Gun. Harbor Freight, Amazon or Aliexpress or the like will have them for under $50. Use it to check battery cells, solar...

Back in April I ordered LifePo4 batteries thru AliExpress from PWOD Official Store. I posted about those batteries and am pretty happy with them. The PWOD batteries were taking forever in shipping, so in June I ordered another set but this time from Morecell Battery Store. I ordered 8 pcs 310ah...

I live in upstate NY on the Tug Hill Plateau. On an average we get over 225" of snow a year. I have had 2 stand alone solar powered webcams running on snowmobile trails for the last 4 years The 175W panel is at 45 degs which is ideal for December here but snow and ice sticking to them is the...

I have 2 310ah 24v LifePO4 battery banks w/Overkill BMS running and saw a need for more battery storage so I went online shopping. Everything coming from China is 4-8 weeks out so I contacted Any @ Docan and got a price on 8 302ah Catl batteries. Her price is good and she could ship from Texas...

Yesterday I decided to grab one of my remote temp sensors that I have on my weather station and tape it to the back of one of my 290 watt panels just to see how hot a panel got. Below is a graph of the air temp and sensor 2 is the panel temp. My panels are on a rack so there is plenty of air...

I have 8 cell I purchased last year that were sold as 310ah cells. I tested 3 of them and all had over 310ah. I top balance them and put them in service a few months ago. One cell is not up to the task and when all others are at 3.19 volts that cell takes a nose dive to 2.65 and the BMS shuts...

I saw this and really want to know what you get for $80...

I just purchased and picked up some solar panel from a guy thru e-bay. Can I share a link to that or is it against the TOA? If it is ok to post what section do I post them in?

I top balanced 1 of my new 310 ah LifePO4 batteries. I want to load test it and purchased a MakerHawk Electronic Load tester thru Amazon. 1st thing I did was make 10 ga jumpers to go from my battery to the unit as what they supply is a joke. I watched a few Youtube video so I better knew how to...

How do I edit my "about" page seem I have not updated it in awhile.

I am presently running two Growatt 24v SPF 3000TL LVM in SBU mode and so far so good but, I live on the Tug Hill Plateau of NYS where we get lots of Lake Effect Snow. (we had flurries this morning) Right now I can go 2ish days with no sun on the batteries I have. I am adding an additional...

100, 200 and 280 ah Lifepo4 batteries seem pretty common. I am waiting on 8pcs of 310 ah batteries and now I see offerings for 420 ah cells. My question is, if I don't care about size, is there a current limit of single cell because of chemistry or something else?
