    Signature Solar LiFePOWER4 batteries charging/discharging differently. My fault?

    A quick update: Since changing my inverter's charging settings, I haven't noticed the batteries being in a different state of charge...as viewed with the four charging indicator LEDs on the front panel. I'll know more when I hook up to the batteries via RS485, hopefully this weekend. (We've...

    Signature Solar LiFePOWER4 batteries charging/discharging differently. My fault?

    Yes, if you are seeing problems. One lead from the inverter attached at the top of a bus bar and the other lead attached at the bottom. The bus bars are not set up for this. You can make it work by adding a stainless steel washer, and carefully tightening a bolt, but it would be better to drill...

    Signature Solar LiFePOWER4 batteries charging/discharging differently. My fault?

    I think I figured out the problem(s). First, not having the charging leads (from my MPPT charge controller) connected at opposite ends of the bus bars (ie. diagonally), wasn't helping anything. Second, I had set the MPPT charge controller to bulk charge to 56.0V, absorption to 56.0V, and float...

    Signature Solar LiFePOWER4 batteries charging/discharging differently. My fault?

    It means I was doing it wrong. However, I've since corrected it. If you watch ten seconds of the Youtube video I linked to, you will see what I did, before and after.

    Signature Solar LiFePOWER4 batteries charging/discharging differently. My fault?

    You aren't quite reading me right. The Signature Solar battery rack comes with two bus bars, a negative and positive. All the batteries' positive leads are connected to the positive bus bar, and the negatives to the negative bus bar, making a big parallel battery. (I'm not talking down here...

    Signature Solar LiFePOWER4 batteries charging/discharging differently. My fault?

    I understand what you mean. And thanks for the advice. I just don't have any laptops that run Windows, nor do I want any. Solar Assistant does the same, and more, just in a way that works for me. (Solar Assistant runs on a Raspberry Pi, talks to the batteries over RS485, and gives me a web...

    Signature Solar LiFePOWER4 batteries charging/discharging differently. My fault?

    I'm a Linux nerd. Any Windows laptop becomes a Linux laptop in short order. I was going to grab Solar Assistant anyway, as I have half-a-dozen Raspberry Pi sitting around. But I get your point: Look under the hood of the batteries.

    Signature Solar LiFePOWER4 batteries charging/discharging differently. My fault?

    I received and installed four Signature Solar EG4 LiFePOWER4 batteries, along with the six-battery rack, in January and was happy as a clam. I noticed pretty soon that they don't charge/discharge identically. Judged purely through the four-LED SOC indicator on the battery, one battery would...
