Inverters see AC-In voltage and freq, but not connecting to grid

Hi Kelly,
Can you offer more details?

I’m about to go down to RMA the unit. Would love for a simple fix.

I suppose I will uninstall and inspect the ACin wires on both sides and also look at the terminals.

Thanks!
Mike

As much as I wanted the easy out with wire burns or bad connections, I finally had the opportunity to check the system again in-person… no wire burns.
I reseated and sanded/cleaned all connections, just to be sure. Double checked grounding, updated firmware, rechecked all config settings… no change.

One thing I am noticing… on VictronConnect, it shows when the unit tries to reconnect to the grid. Towards the end of this process, it makes a change to its 60Hz buzzing noise. I’m not sure if this is related to trying to connect to the grid or if it’s a load it is supporting on the inverter side… The noise happens at about 5sec in

I was able to get a Signature Solar RMA, but we have to get the unit back to the US to then ship it… gaaah

The pass through contactor was not getting a good connection. I had take the bottom off the quattro to get the top of the contactor. I removed the contacts out I put them in a lath and very lightly trued them up. There is a thin layer of silver on them. So do not take too much off

Hi, I have the same problem. No network connection. Can you give me information on how to proceed? Complain? Thank you very much

You can start the warranty process with the supplier.

Thanks you
