Factory reset for EG4 6500EX-48?

Is anyone aware of a procedure to factory reset the EG4 6500EX-48? I feel like I might have some corrupt settings and would like to set everything back to the defaults.

I'm not aware of any way to factory reset the inverters. SS might know of a way. Only thing that comes to mind is going through the manual and changing all your inverter values back to the ones marked as "default".

I’m working on a new video regarding WatchPower, I did see there’s a Parameter to “Reset to Defaults”. Not sure if it works because I really don’t wana to have to re-enter all my settings, but might be something worth looking into.

The manual states “This function is to restore all settings back to default settings”.

If you happen to try it, let me know if it works.

Since I'm trying to diagnose s problem with setting #2 (max charging current) I decided to test the PF command to reset all the control settings. I had to sent it to each of my 2 inverters and it worked like a charm. All things reset, and the annoying beeps when pressing s button were back.

Then quickly disabled the annoying beeps, set 2P1 and 2P2 and reconfigure all the things. Don't forget about setting 42 if you're using the latest firmware (set it to enable to disable internal N/G bond).

Update: I used mpp-solar from the command-line on the Pi and ran:

Awesome! Thanks for testing!

I never wanted to spend the time having to redo all my settings.

I have a question -- will this command set Register #28 on an EG4 EX6500 inverter (where you can set the inverter to 2P1 and 2P2) back to default as well, which is a stand alone inverter and not a multi-inverter/multi-phase configuration??? Please advise!!

I seem to remember it does.

I am trying to use mpp-solar to reset my EG4 EX6500 to factory defaults.
I have set up mpp-solar on a Mint installation with a debian base and followed the ubuntu install instructions.
Using a python VENV, I got everything installed. I'm using the factory EG4 USB serial adaptor and the OS sees the device as /dev/ttyUSB0

So far so good....
When trying to run the reset command PF, I am getting this error on the command, in fact I get it on ANY command I send to the unit. I've tried the default PI30 protocol as well, but get the same results. What am I doing wrong? Any help would be appreciated!!

(mppsolar) root@mega:~# mpp-solar -p /dev/ttyUSB0 -P PI30MAX -c PF
Command: PF - Set Control Parameters to Default Values
--------------------------------------------------------------------------------
Parameter Value Unit
validity_check Error: Response to short

That's probably because you need to set the baud rate to 2400bps to be able to communicate with the inverters.
