6000ex briefly losing power

[Dralkyr]

I have 2 6000ex in parallel powering our home. We are off grid so that system is out entire power. We've noticed this before but last night our power cut out 3 times in the middle of the night for about 5 seconds. I don't have to do anything for power to come back, just wait. The batteries are full, there are no faults on the inverter, no breakers trip, etc. But it's still not a good thing to have power cut out.h Tis does happen during the day, too, so it doesn't only happen when there isn't any PV input.

What could possibly be the cause?

I had three EX's running my house for almost two years. They worked fine except for random shutdowns. Sometimes it would not happen for a month. Sometimes it every couple of days or every two weeks. It was not related to load, pv or any other identifiable reason. It always restarted by itself. Most of the time this was fine, but sometimes it would reset all the parameters. It would change over to 50hz and battery charging settings would be way high. Two would be on one set of parameters and one would be different. I finally gave up and did the upgrade program to the XP's. THese seem to be working a thousand times better than the old EX's. If you are able, I would upgrade. I suspect the internal changes the factory made to EG4's original specs are the cause, or maybe bad firmware, in any case I think you only have more of this to look forward to.

I manage to get rid of the quick shutdown by re routing the comms cables away from the Hight current/voltage wires now my inverters are working fine since then.

Did you ever figure out what the problem was?

That sounds like a nightmare.
