While you are at it, check DC voltages between the Sunny Boy DC inputs to

If the DC Fault is not eternal then it must be internal to the inverter.
This could be a dangerous situation. I would proceed with caution.
Try completely isolating the PV from the inverter as a start.
Good luck.

Optics interface. This is also why a good AGS system
examines battery voltage over time.
I no longer install Outback FNDC units. Without them there is no SOC
reading. I don’t install Sunny Island systems—they are SOC centered and
suffer for it.

Thanks for the reply. My understanding is that a new bulk process begins
every time AC power is reapplied. Rebulk only applies if AC power is
maintained after absorption completes. That’s not what is happening here.

Segregated load distribution. Simple, automatic.
I don’t get why they put 200 amp pass-through on an inverter that can only
produce 62.5 amps.

I tried running 48 VDC muffin fans on battery voltage. They failed. I
switched to a Dc-Dc converter (12 or 24, can’t remember) from digi-key and
problem solved.
Point being battery voltage ranges may be too extreme for some components.

Good question. I assumed some kind of FET circuit but that is only my
assumption.
However an open relay exhibits some fairly high impedance.
The symptoms indicate the SI shuts down but the batteries remain connected.
Something allows 69 volts on the battery terminals…

Thanks in advance for any insight. I hope I am wrong about this and I am
just missing something. I also hope revealing my headaches will help
someone someday…

Appliance manufacturers have their own requirements that are not the same
as the NEC requirements. As long as you are not modifying the manufactured
assembly you are not responsible for compliance of that appliance. By
appliance, I mean the solar module, microinverter, etc.

seems they incorporate a lot of complexity that may make them
unreliable unless charged and discharged very carefully. I do not believe
AC-coupled charging is a good way to charge lithium batteries, or any
battery.

In my opinion AC-coupled battery charging with even the newest inverters is
a crude affair. I am not a fan.

let the generator fill in the deficit until Monday.
