In summary: my MPPTs are dropping out of network mode and going into standalone mode and I don't know why.
The past couple days have been sunny so I turned off the grid 'mains' to check out the solar side of system in preparation for some upgrades later this month and I've noticed a behavior which I can't explain.
Normal operation (full power coming from MPPTs):
Normal operation (in ESS mode):
I've completely power cycled the MPPTs, disconnecting from PV, and disconnecting from DC, waited a bit, then connected back to DC, then supplied power via PV.
Basically, I can't explain why the system would it drop out of the network status ESS into standalone, (drop out of slave mode into standalone mode)?
Unless maybe I have a bad RJ45 UTB cable as well?
Here are some of my other settings.
Both MPPTs are connected via Ve.Direct to the CCGX and over Bluetooth to the Smart Battery Sense on the batteries.
If I observe the LEDs on each of the MPPTs, I see that they primarily stay in Bulk, though occasionally the blue Bulk LED flashes off, then back on.
But after a minute or so, seeming at the same interval that they drop out of ESS, they go into float, if only for a brief second, then back to bulk again.
You can see from the VRM output for today, that each MPPT controller is behaving nearly the same. I would expect to see these lines to be a curve of constant output, vs the spikes & dips.
Additionally, if I watch the volts at the shunt.
When the system goes into 'standalone/float', the volts drop to 13.07v
Any help or advice or places to look would be appreciated.
