    What a difference a month makes.

    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...

    Mixing EVE and CATL in the same pack

    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...

    Solar Panel temp

    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...

    My Beginner Suggestion

    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...

    MakerHawk Electronic Load Tester Issue

    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...

    Single Cell AH limit

    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?

    Simple Temperature check.

    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...
