    Victron multiplus II pass through failure

    I am attempting to hook up my unit but when plugged in to power it doesn't pass anything through. Of course charging doesn't work either. I have 121 and 119 volts going into it. The inverter portion is working great.

    I only have one battery hooked up right now as I am waiting on cables to hook everything up but from what I've read that shouldn't matter.

    I am starting to think I have a faulty unit, any ideas where to look?

    Have you tried using the phone app to set different settings for the inverter, Off, On, Charger Only, etc? I am at work so I am going off memory on what settings are available.
    Have you (carefully) put a multi-meter on the A/C out lugs to check for voltage?
    Do you have a master breaker in the old converter that has tripped?
    Is the "Mains On" light on the front of the inverter on?
    Good luck, hopefully some real expert will chime in soon.

    Yep, tried the phone app, I have ac going in but nothing passing through. The inverter runs giving me ac out ok. Weird. The only light that is on is the inverter light.

    I've been emailing tech support but we're not getting anywhere. I'm starting to think I have a bad unit out of the box.

    Interesting issue. The "Mains On" light not being lit does make it seem like a defective inverter. I hope you and Victron tech support can get it resolved. Please let us know how things go.
    Good luck.

    Can we attach files on this forum? I'd be curious to look at your VeConfig file. Also do you have VRM setup at all (like a GX device or something)?

    Can you screen shot your assistants tab on VeConfig?

    Yes, try switching off (do not use) virtual switch. I've had issues with the virtual switch before.

    What position is the physical switch on the inverter in?
