    LV2424 and Growatt 3000 won't turn on with 24V from bigbattery

    "unless there is high resistance in your wiring such as poor connection" Thanks Bud, you are the BEST! It was a bad loose crimp on the connector. I wouldn't never thought a cable would be bad since I bought the cable "professional" made. I put in a new connector today and it boots up. Going...

    LV2424 and Growatt 3000 won't turn on with 24V from bigbattery

    If I purchase an Ampere Time 24V 100Ah LiFePO4 battery (to rule things out), would it be okay to connect this battery with the 24V LiFePO4 Powerwall from bigbattery (they advertised 3KW, so 125Ah) via bus bar? I was told it is bad to mix brands of batteries.

    LV2424 and Growatt 3000 won't turn on with 24V from bigbattery

    So it also shows 26.5V dc at the lamps wires? Yes What is shutdown mode? Yes, I used the clamp on meter. Connected to LV2424, turning it on. Current is at 0.07A, 4.9V (this dropped from last measurement)

    LV2424 and Growatt 3000 won't turn on with 24V from bigbattery

    I will double check the BMS connections. I do not have a battery charger. How can I test with the 12V car head lamps? Is this something I can get from wal-mart or autozone?

    LV2424 and Growatt 3000 won't turn on with 24V from bigbattery

    First my simple set up, One LV2424 connected to four 24V bigbattery connected in parallel, connect to solar input and grid input and output. I have been working at this issue for over 2 month now, I thought it was a bad inverter, now I am not so sure. This setup has been running fine for over...

    MPP LV2424 grid-tie mode efficiency

    @ohseedee , You might be over voltage your lv2424, at least that is the case with mine. Try connect your solar panels in parallel configuration.
