    DC solar trailer - forklift BATTERY CELL EXPLODED!

    1st what voltage and current are you charging at? it would have to be serious amps to create steam... 2nd... have you measured each cell when at 90%+ charge to ensure each cell is the same voltage? I would guess the cell was way over voltage

    Most efficient way to 12v system from 24v?

    I use a generic 100A generic lifepo 12v battery. And a victron 75/15 SCC to connect 24v to 12v.. I can set up a proper charge profile

    Externally control Growatt SPH 3600 via RS485/Modbus

    solar assistant will do that with my growatt 3000 spf

    Solar powering shop A/C system - looking for controls and direction

    sadly a starting capacitors don't store any energy on AC voltage.. what it does is phase shift the sin wave on the start windings allowing the anglers difference from the run windings to start the motor spinning..

    Quick charging question - Bench top and battery

    the voltage at the output of the SSC and the battery should be the same.. if it isn't then it's the wire or connection.. read by a volt meter

    BMS and mppt victron not showing same voltage

    14v can be just takes longer in absorption phase

    Solar powering shop A/C system - looking for controls and direction

    1 you will need soft starts on each AC compressor 2 yes eg4 and growatt will do transfer switch 3 you will need a battery to start the units and deal with moving clouds.

    Quick charging question - Bench top and battery

    you need bigger wires on your charger

    BMS and mppt victron not showing same voltage

    get a volt meter 1st.. how long is the wire between battery and victron

    Inverter high voltage alarm, smoke coming from USB ports?

    high cell shutting down your battery.. lower your charge voltage. what battery? do you have Bluetooth acces to it?

    No AC output on Growatt 3000 watt 24 volt all in one

    on new install had to give the input 120v

    Wiring up my generator plug for backup power. Wiring question.

    to run off your 50a socket you will need 2 chargers or one 220v charger

    Lowest electric bill ever....

    might be able to cut back a few loads during an outage and be good

    DIY home battery backup no solar

    you say 25amps at 220v is 5500 watts... and will need lots of battery for 30 hours...

    Used 18650 failure rate/sanity check?

    how much are you saving compared to 32x 280ah lifepo cells?

    Stacking Multiple Energy Storage Systems

    legally your are supposed to pull permits before work starts. they do have exceptions like weekends for emergencies.... that's where red tag stop work tags come from people that didn't

    Off-grid solar and ham radio noise

    what if you run your ham on a separate battery pack and you isolate as needed

    Problem with LiFePo packs not discharging/changing evenly

    before I switched to 24v 280ah. I had two 12v JK BMS and one always had higher amps at 13.2v.

    Problem with LiFePo packs not discharging/changing evenly

    I think some BMS have slightly different resistance and Lifepo voltage is so flat in the middle it allows drift. I would think in the upper and lower in the sharp voltage curve it would equal out

    New EVE 280Ah cell only deliver 240Ah! Probable causes?

    what where your testing parameters? where are you measuring the amp and with what? where your cells top balanced? what was your stating voltage and ending? where you using a BMS? what was the pack voltage when the one cell hit lower limit
  22. GSXR1000

    Problem with LiFePo packs not discharging/changing evenly

    how is battery 4 at a different voltage? BMS disconnected? battery 4 is at 3.16v per cell no where near 0%. as long as the batteries are at the same voltage. once they get into the sharp part of the curve it will pull current from the fuller battery

    adding a battery to existing system

    agreed I was saying in series.. just .2 volts from each other

    adding a battery to existing system

    they have to be charged while in parallel and neither fully charged at 1st

    Growatt 3000SPF not charging at full solar

    well now it glitched out and says it's a a 48v.. ughhh. didn't touch it

    Micro-Air Soft Starter on 5 ton AC? Variable speed AC vs Single-stage

    you can do RLA isn't listed because it variable frequency so it "ramps" up to speed and no surge current.. perfect for off grid

    Soft Start on 2 Stage AC

    xr17 is a single speed compressor so a soft start would be fine.. it just closes a scroll bypass selniod to use 100% of the compressor

    Growatt 3000SPF not charging at full solar

    so when I have a large load like the air conditioner my solar input is 1399w but without large load on the inverter it ramps down to 679w any ideals?

    Anyone had trouble with 12v battery at Positive end draining?

    no matter how balanced your 4 batteries are when you run them dead like that one will Always turn off first (the 3 volt thing)

    Cell voltage rises in seconds during charging with Victron 150/30

    it rises so quick because your battery is already at 3.2v per cell (100% charged)

    LiFePo4 Cell went up in smoke and flame!!

    the vent didn't let go.. that looks like a heat issue with current and bad connection appears the terminal melted away.. what was on?
