Hi @BtcDan
2620 indicates a 48/3000 Multiplus, and it should be fine to use in an application like that. 158 is quite old firmware, and I'd go all the way to the latest 502. I'm not sure if your CCGX/VRM can do that large a jump, but you may find it will throw a #1342 message because the CCGX is too old anyway. So you'll likely need to buy a MK3/usb adaptor and use VEFlash software on a WinPC. See the Victron website. The firmware file is available on Victron Professional (sign in needed).
I have a Mk3/usb adapter. So I can update firmware with VEflash (already installed on my old windows laptop) with the 2620502.vff file. correct..
I it best to switch inverter to charge only do do this.. or even off?
Will I still be able to talk to inverter using mk3/usb via VEconfig/ or mk3/usb Victron connect?
TIA
Leave the Multi turned fully on. When you plug in the VE.Bus cable from the MK3, pull out the VE.Bus cable that goes to the CCGX. So it's standalone, with no chance of interference from anywhere else.
Don't forget to save the configuration file and upload it after the fw update.
Don't have the other 'talkers' running while VEFlash is doing it's job.
Thinking I should probably get a second bluetooth adapter so the two MPPT can talk to each other..
It should still be ok to use the MK3. But that said, I've never done it myself. A GX (especially hooked to VRM over the web) is a quantum step up, and you may never want to use the MK3 access again once you experience it..

Good work. Hope you didn't find the process too challenging. Thanks for letting us know.
Good luck with your 'expansion' too. :)
The rPi has often lost all devices plugged into it, I "think" it is a bad termination of the plug into one of the mppts - as it doesn't happen if I unplug that usb.
VRM is showing my I ca update the multi now to V506, but I'm hesitant to do another upgrade, via VRM.
Are there settings I need to make before adding a grid tie inverter to the AC output?
Re the grid-tie. Depends how you do it. Some complexity possibly involved. Maybe hit the website for technical articles, etc. A starter.. https://www.victronenergy.com/live/ac_coupling:start

Even without the bt adaptor (via VRM).
