[RE-wrenches] Magnum 4024 PAE inverter w/ ARTR and AGS

[Michael Morningstar]

I just encountered the same thing. I upgraded a clients Discover AES to a
Helios AES and after a few months what you are describing started to occur.
I came to the same conclusion and all I could offer my client was "looks
like no more AGS for you until we can upgrade to a Victron system.
