    Results of testing new panels from Santan Solar

    I like it but it has limited value for a homeowner like me. The price was to good to pass up and I am a certified member of TEA* *Test Equipment Anonymous (for people who have a lot of GAS**) ** Gear Acquisition Syndrome

    Nice thing is it comes with a reference cell, so when you test the panels you get accurate results no matter what the sunlight brightness is

    Results of testing new panels from Santan Solar

    I know they are Trina Solar panels and yeah I purchased them as used, I think it was $40 a panel at the time. My daughter was able to get me this when she was in the PhD program at Texas A&M.

    Bumping an old thread. I purchased 2 pallets of these panels in 2019 or 2020 (can't remember) Any way they have been in storage this whole time, outside in the rain, moved from FL to TN on an open trailer. I did not have much hope for them now that I am getting my act together. I decided to...

    It's a load bank. Initial Investigation I found a vented cap and a bad 5w resistor. When I have time I'll do some more looking.

    Docan or 18650batterystore for 280/30* cells?

    FWIW my EVE 230's all seem to be testing fine so far. Admittedly I am only 4 in, but so far so good.

    Cell 2. I took this one to 2.6 instead, and honestly I'll probably raise it to 2.7 in the future. 234.25Ah, 749.454 Wh. Cell was charged to 3.62 .22 mohm

    First 230a cell test complete. I had to use the Kunkin tester because my big tester obviously is not working :) 232.29 Ah, 742.41 Wh. This cell was charged to 3.60V and discharged to 2.50V
