EG4 6000XP Rapidly Entering and Exiting bypass mode!

What Firmware is your inverter on?

Have you had this issue before, or did it just recently happen?

Did you get any alarms while this issue happened?

Firmware is at version: ccaa-180D0E. I tried to update 3 or 4 few times... but it always "Failed".

This is the first time that I can recall this happening. I've had it in use for a month or so but just yesterday moved an additional circuit (hybrid water heater) to be powered by the 6000XP.

None during this period. I do get a fair number of EPS Overload events because I have a discharge limit of 45A (small batteries, small wires). When my loads exceed this it usually flips over toe bypass mode for ~5min as expected, but this was quite different.

I have remote support enabled if you'd like to take a look.

There's also a possibly related symptom. I just installed a lot more solar, so my batteries are fully charged fairly early (and move into the "float" voltage). It seems while I'm in this phase that it's a *lot* easier to hit EPS Overload, even when my loads don't seemingly exceed the limits. I just had an instance where a load spike resulted in it being in bypass mode for ~1 hour even though the spike was seemingly short (See screenshot).

I've updated to the latest firmware (ccaa-190D0E) last week and can confirm it's still occasionally happening. I just had it happen this morning, and the symptoms are the same, rapid cycling of bypass mode on and off. Still no alarms or events while this is happening.

A hot water kettle and the toaster (both resistive loads) at the same time (though on separate circuit legs) pushed me over the discharge limit. It would flip to bypass mode and then back every second or so until I dropped one of the loads. I'm able to reproduce this consistently (I just tried again).

It's clear to me why it would switch to bypass mode as I'm exceeding the configured discharge limit. But it's not clear to me why it would immediately switch back to batteries. This seems like a bug and I have to imagine it's bad for the relays to constantly switch back and forth, I know all my lights dip for at least a couple of the 60hz cycles. I'm hesitant to move any more of my circuits over while this is still happening.
