Thanks for the reference Jason. I only have 2 EG4 18k systems in the wild, one of which I've been promised a hardware upgrade for over a year now (to fix inverter shut offs due to relatively small imbalanced loads).
Not being up on cyber security, I only vaguely understand what is being warned. As best as I can make out, the recommendation is to put the system behind a robust firewall and only access it via an up-to-date VPN and only with continual monitoring or remove it from internet connectivity altogether. If anyone can put the warning into a format that those of us without cyber training can understand, it would be very much appreciated.
