Intermittant "fault" display on mppt 100/30

System is:24v 5kw quattro, lynx ion 1000, 4x he lithium batteries. 3 mppt smart 100/30,ccgx

I am bench testing the above system, I noticed today that that the mppt controllers are all doing the same thing,

When I look at them in the ccgx page the status flashes between "external control" and fault. When external control is displayed charging is OK, when fault is displayed charging stops, this cycle continues every 6-7 seconds.

The controllers are not faulty, because they all do it, it's not likely they have all failed at the same time.

Any ideas??

Hello @Christyler
Did you update all devices to the latest firmware?
Can you list the firmware for each device to make sure?
If you need more information about checking the firmware versions let me know.

best regards

Yes apoliges, I should have mentioned all devices are on the latest firmware.

I can't explain it but I did nothing, and it's all ok now ??

That's why I am bench testing.
