This sure seems like a bug in the firmware. Can your team look into why the 6000XP would be trying to exit bypass mode 1sec after entering it?
It sure seems like it could end up destroying something if this happens for hours when I'm not home. I can reproduce it reliably by adding 1000-1500W resistive loads on both of 240V legs.
Are you able to post screenshots of your settings please?
Yes, here you go.
But, regardless of settings, I thought the 6000XP should stay in bypass mode for 4-5 minutes before attempting to exit (for W28 errors). Normally it does this just fine, but for some load conditions, it tries to exit *right* after entering causing a rapid oscillation of the bypass relays.
I think I've figured it out! I was able to take a slow-mo video of the screen while reproducing the problem.
What's happening: A high load on the inverter briefly causes a voltage drop *below* EOD cutoff voltage. It then switches to bypass. Because the loads are off the battery and solar is charging, the voltage then rises *above* the EOD + 3V required for recovery and the inverter switches out of bypass (sagging the voltage again) and the process continues, rapidly.
A fix for the inverter would be to have a required delay between reaching EOD before it's allowed to enter into the EOD+3V recovery. When I expand my battery and used closed loop communication, this likely will be a non-issue.
This is happening when my battery voltage is right around the EOD+3v for recovery.
Here's screenshots of the inverter screen for both of these states:
That makes sense, any idea how long you "high load" would be occurring if it wasn't going into bypass? The reason I ask is my old system had a prevent nuisance timer so if the there was a brief drop it wouldn't affect. It was a nice feature but once I had my battery capacity where I needed it became a moot point for me.
Sometimes the easiest solution is the best solution.
Sometimes not.
@joel-brodeur -- I found I could reproduce the problem by using a toaster and a hot water kettle at the same time. Enough to cause a voltage sag, but not enough to trigger EPS overload.
