  • Equalizing the bank

    Greetings fellow sun followers,
    With the sun at such a low angle and lots of overcast days, my bank is getting a useful charge, but not enough to kick the controller into equalize mode and I don't want to go too long without doing so. Haven't seen bubbles in at least a month. Is there a recommended 'forced' equalizer device I can add to the system? Other options?
    Obviously a noob. Thanks,
    Jack

    Yes, watch the weather for a forecast for a fairly sunny day. That morning about 7am, start the generator, and Bulk charge the bank for the couple hours needed to get thru Bulk and at least part way through Absorb. Then you can initiate the EQ cycle. The further along in ABSORB you can get before judging you won't have enough sun left to get some EQ done, the better, you can't EQ bateries till they are charged, otherwise you are merely charging them.
    This post here, talks a bit further about the process.
