Solar Joules are catch and release
You keep saying that, but I do not think that means what you think it means.
[Resolved] System is down Sungoldpower 8K Hybrid inverter - Need urgent help

Is that even a term? If the circuit is OPEN, no current flows.
SHORT circuit amps, I have seen before. (Isc)

Exactly my point, mvreddy48 doesn't seem to understand the basic terminology or the use of his test equipment, which is a bit disconcerting when he's playing with high voltage DC strings. Hey, everyone has to learn sometime, but if you are getting the basics wrong (or backwards) that's the time to take a step back and understand the system.
Not the same. You other image showed a connection to the solar panels. This one shows voltage only but no line to the inverter. It also shows a full battery, not in Bypass and 1 amp load on the battery.
Something is going on with your setup but it is a bit hard to diagnose remotely. Perhaps simplify things by turning off utility and just run a load off the inverter for a while and see if as the battery drops in charge so that your solar begins to feed.

OP please be very careful as you are messing with 320 volts DC and that shit will hurt you bad. It is obvious you have limited electrical knowledge but you are learning and getting there so well done, just please be careful.
Thank you, I will post it soon.

Thank you!
I charged the batteries via Utility/Grid yesterday night to SOC 90% by changing the parameter 6 temporarily (to Utility can charge batteries if Solar power is not available) and it charged fine.
Thank you, I will review this thread.
Sorry for the use of wrong term. I meant short circuit amps. Apologies.

I think that was a good test to rule out any issue with the charging, connection to battery bank and battery bank itself.
This leaves only these options for the problem:
* AIO's MPPT (unlikely since both of them show the same failure to charge)
* wiring between panels and AIO.
Is it still configured as 2P4S? No combiner box, I assume. As was suggested before, maybe change the panel configuration to 1P4S .. less connections, to locate a bad connection.
* a problem in a solar panel???

It's long and all over the place but I linked to the settings I've been using successfully for months now.
They are for open loop 16S LiFePo4 with grid usage as last priority.
I'm hoping you can figure out the root cause quickly.

I wonder if the open-loop thing is causing you problems. Is it possible the battery is out of balance or just needs its SOC meter reset?

Highly doubtful. I have over 6 MWh through 2 different inverters, never used battery--inverter comms.
It's possible but his display should show if it were charging with solar.
Attached mine for reference.
Edit - proper units.

Lmao words tiniest array.
01 is UTI currently, usually it is on SOL but the moment it is put on SOL it starts pulling the Amps from battery (which I charged last night through Grid).
For 4 and 5 the voltages are default 43.6V and 56.8V.
7 is 60 amps.
I don’t have setting 71. The parameters are until 68 only for this inverter.

Have you tried 01 in SBU?
What is setting 06 currently?
Have you tried a complete power down and restart?
Nothing was changed before it stopped charging from solar?
