EG4 6500 - stuck low PV voltage

I wanted to give an update. They had me try to reflash the firmware and after doing this it appears to have fixed the issue. Don't know why the first time didn't make it work but appears to work now. Waiting for a cloudy day to see how it does before I say it is fully fixed, but it is looking good so far.

That's great news! It's interesting, I've heard of a few cases where it seems like the firmware didn't update completely. Not really sure what's happening there, but glad to hear at least for the time being things seem to be resolved.

Now we just have to get @mountkay to update his to see if his is fixed too... ?

What firmware are your inverters running?
I was having on off issues and upgraded to 79.70 due to the inverters turning off and on randomly.
After the firmware upgrade the on off issue is still random and have a new issues where the inverters turn on and off when the PV power starts to increase at sun rise and when the batteries reach 100%.

My two inverters are now doing the same thing, did you find a solution? "

I also see 70 volts on pv 2 input on just one inverter. pv2 is not connected to either inverter.
 
Can you keep us updated, please?. Do we know what is different in the replacement inverters that are being sent out, if anything?. They seem to work out.

If they come manufacture date of 10/2022, there might be problems.

I installed replacements yesterday, I have a thread showing what I found. The replacement inverters are worse than what I had before. I'm not the only member who received replacements lately and had problems. One member lost his TV after installing the 10/2022 replacements.
 
My inverter just recently started doing this. It was stuck at around 250w until i shut everything down and turned it back on again. Production date 10/22
