    battery discharge with 2amps with no loads

    coms are very important to me because i tried without it , the inverter started to detect wrong battery voltage and wrong state of charge

    battery discharge with 2amps with no loads

    the screenshot is from the inverter but what i mean is i have no control over charging parameters because the battery is telling the inverter what it needs via communication cable i believe the battery bms is determining the charging values .. because as we speak the battery is discharging and...

    battery discharge with 2amps with no loads

    Can you tell why my battery bms after charging with bulk voltage with 57.6 v to 100% it changes the cv and float to 50v can you tell me why this happens?

    battery discharge with 2amps with no loads

    today i disconnected the communication cable from inverter, the 2 amps discharge dropped to 0.44 amps , battery type set to LIB , once i reconnected the CAN cable the discharge returned to 2.15 amps once again. this is very confusing ! can i connect the battery bms to pc to see what's going on ?

    battery discharge with 2amps with no loads

    it doesn't mention this in the manual, if that's the case it's very dumb to function like this

    battery discharge with 2amps with no loads

    correct, but I'm using it with a change over switch.. meaning inverter output is not supplied to loads unless I flip the switch, that's why I'm confused on where the 2 amps are going. because the inverter is powered by grid when available

    battery discharge with 2amps with no loads

    that's correct when battery is powering the inverter.. but in my case utility is powering the inverter, i believe battery should stay in float voltage without any discharge, am I correct?

    battery discharge with 2amps with no loads

    hello everyone. please help I'm using Sako 6.2 48v inverter with 48v 120ah lifepo4 battery from sako .. using it as ups charging from Utility only. after charging to 100% , and charging stops, the battery start to discharge with 2.15 amps , while grid is on and no loads are connected.. the...

    charging and voltage

    the outages around 7 to 8 hours daily, i reduce the consumption to 450w and i go through it every day when the grid comes back the voltage is around 25.4v i reduced the bulk charging to 27.4 because i don't want to fully charge it and increased the amps to 30a because it was taking to long...

    charging and voltage

    i installed a UPS system using felicity solar hybrid inverter and 2x12v 200ah blue carbon lifepo4 batteries for a 24v system, because we have daily power outages and i can't afford solar panels right now. my question is i charge my batteries with 28.2v bulk and 27v float. utility charging...
