Quattro 5k Overload

I have an installation with 2 Quattro 5k 48V setup in a dual phase system. The system has been working well for some days. We were running some loads with a total power aprox 6000kVA, when the system shut down.

We have been trying to restart it but the masterQuattro (L1) will remain blinking the Inverter on bulb and the slave (L2) will turn flashing some of the leds and then will light only the overload led and shut down after.


The L2 Quattro goes to bulk and inverter and then goes to overload.


We attempted to start the system in charger only and it started well in. Bulk and mains on, but shut down after 30 seconds.

What can I do to restart the system?

Difficult question to answer. Can you provide a diagram and pictures of how everything is wire?

This is the system. We have as you can see a dual phase, grid connected with PV and Baterries.

We were able to restart the system and the only issue we have now is that the L2 output seems to be a passthrough and not been supplied from the busbars and the PV in operation.

How can I check in the settings if the Quattro is having a DC issue and then how should I check it physically?

Please provide:
-what (kind of) batteries are you using (chemistry, bms?, etc)
-pictures of wiring / connections to batteries, inverters, fuses / breakers / etc.
-screenshot of inverter parameters (DC/AC voltage, state, etc)
-anything else you can think of

without that it's only guessing.
