    Multiple Battery Banks

    Is there a limit on the # of battery banks that can be added to a system? I have 2 - 48v-280ah battery banks now & have plans to expand. They are connected to 2 inverters, 6kw & 4kw. Everything is working great but we need more storage capacity. We would like to be able to run 2kw for 24hrs...

    cable length

    It's probably on here but I can't find it. I have EVE 3.2v 280ah 16s 48v battery bank, going to add more battery banks in the future. My BMS has negative cable length of 24" from battery to BMS & 24" from BMS to bus bar. Does the positive cable need to be the same length as the negative? If yes...

    Wire to CC

    I have a 6-string combiner box, have 18 panels wired 3s, used 10ga PV wire to combiner box. From the combiner box to the Charge Controller I need 4ga wire, about a 50' run. All I can find is building wire, stranded THHN/THWN-2 Is this what everyone uses?

    Battery bank, stop charging at 90%

    One final question (I hope), think I have finally figured it out. How do I stop charging at 90%? Right now I have a couple disconnects to turn off strings of panels. There must be a way to do it automatic but can't find it. Thanks for all your help!!!!

    Bottom balance cells?

    The more I study the issue of building a battery bank & balancing the cells the more confusing it gets. I have EVE 3.2v 280ah Grade-A cells, 16s-48v Just watched 2 videos where Will says to bottom balance the cells for most home solar systems. They were from 4 years ago, has something changed. I...

    charging 3.2v cells

    Just received my new ZKETECH A40L battery tester. Can't find how to set the cut-off point for amps. I have EVE-280ah 3.2v cells. The way I understand it, set charging voltage to 3.65v & amps to 40. Does the tester know what size the cells are or is there someplace to in the software to set it...

    eve 3.2v 280ah 16s 48v

    What should the charge controller voltage be set for EVE 3.2v 16s 48v battery bank? Aims 100 amp charge controller lithium setting = 57.6v, works great until battery bank gets to 100% SOC. The thing keeps charging until alarms settings go off at 3.65v per cell, then at 3.7v the whole system...

    Aims 6kw 48v inverter transfer from shore power to battery

    I have an Aims 6kw 48v 120/240 split phase inverter. Just upgraded to lithium 280ah battery bank. I use it in battery mode, when batteries run down it transfers to shore power, no problem. The issue is when the batteries are charged back up the inverter will not transfer back to the batteries...

    36v battery, help

    I have a chance to get a used 36v battery at a good price. Have not looked at it but it's a monster, out of a forklift & made to last all day at a busy warehouse, battery weight is over 3000 pounds. Is there a good 36v inverter I can buy? I have a 48v system in service, is there any way to add...
