    Recomended battery voltage to charge with 20KW

    Yes, I see what you mean. I had thought that if I used a system with separate charge controller and inverter and not all in one, I would not have this problem, but now I realize only the charge controller would have to fail and it would have the same effect on the interconnects. I will 100% put...

    Recomended battery voltage to charge with 20KW

    Why would the interconnects be at a higher current if an inverter died? The only high wattage is the charging wattage. If the inverter dies, that doesn't mean, the battery stops charging, assuming I have a separate inverter/CC system.

    Recomended battery voltage to charge with 20KW

    Do you mean to break each independant array into three parts? That would be okay, and I will probably do that. All I want is every array to be exactly the same!

    Recomended battery voltage to charge with 20KW

    Yes, of course I have to think everything through a lot with such a big system. And I don't feel safe relying solely on my imagination for possible dangerous scenarios, so I will definitely put breakers everywhere where a high current situation could happen and could be dangerous. Also, before...

    Recomended battery voltage to charge with 20KW

    I would have to mount the independent solar arrays exactly the same, though, with the same tilt and azimuth, just for safety in case the batteries don't get a full charge for a few days. But yeah, it shouldn't be a problem as long as I make the arrays the same and have no shade over them. Thanks...

    Recomended battery voltage to charge with 20KW

    Yes, that makes a lot of sense! In the separate systems, would it not be a problem if each battery pack had a slightly different SOC and voltage?

    Recomended battery voltage to charge with 20KW

    Yes, that's right, I would be consuming 230KWH in 3 days. The thing is I live in a pretty sunny area and have relatively few cloudy days (40 days of rain last year). Also, the load is not strictly critical, It would still be OK to have no power for 10-20% of the year. I'm just trying to...

    Recomended battery voltage to charge with 20KW

    Thanks for the reply! Actually, I meant 20KW of charging power from Solar panels. Sorry, I could have expressed myself better. What I mean to do is build an off grid system with a 55KWH battery and 25KW of solar panels. That's why I would need around 400A of charging current with a 48V system...

    Recomended battery voltage to charge with 20KW

    Hi, IM relatively new to the solar space and this forum has already helped me greatly in understanding most of the important stuff. There are still some things I am not completely sure about yet, though. What I can't seem to grasp is how to charge a single battery with high wattage of, for...
