    Centurionsolar reacted to Youda in INFINISOLAR warning #07   
    Hi @Blinkwater9
    "Warning #7: AC input island"
    To me that message says that the Public Grid is down and the inverter is operating in battery mode. Loads are ON, the energy is provided from the panels and the batteries. The Grid relay is disconnected, so no energy can flow into the Public Grid (and hurt ESKOM technicians that are working on the powerlines). Once the Public Grid will be back ON, it will take couple of minutes to reconnect, since the Infini will measure the grid values firts, then perform a safety delay and then it will close the grid relay again. Duration of the safety delay can be set here:

     
    You should be able to simulate this warning flipping the AC input circuit breaker while inverter is operating.
    I tried to simulate this myself, but since all my InfiniSolars are operating in the Off-Grid III Mode, it's generating the two different warnings in my setup:
    Warning #2: Line voltage loss
    Warning #4: Line frequency loss
    Regs,
    Youda

    Wow!
    This is really valuable data. Not to mention a firmware (you called it a patch, but it's a complete re-compile) that supposedly has the fix.
    It's possible that I can find out what they've done, and patch other firmware for other models. But it seems to me that if there is a fix for this model, there should soon be a fix from the manufacturer for the other models as well.
    I just checked, and the main premature float bug is still present in the this latest factory firmware, version 71.71. Sigh. But we can deal with that.
    Thanks for whatever part you had in making this happen.
