@SignatureSolarJames I'm debating on grid backup system for a remote home where solar doesn't currently make sense (roof designed to hold snow, and snow load can exceed 10 feet packed), and have been thinking of using a Chargeverter in parallel with a MultiPlus-II 48/3000/35-50 120V (UL), and a pair of EG4 batteries to power a critical loads panel (week long outages are very common). Having a ramp-on feature would be great - could combine it with a contactor and control whether or not the chargeverter is powered (there's an existing, oversized propane generator that we're trying to drastically reduce its usage for most outages, and the fast-charging LiFePo4 combined with just powering critical loads can mean 1 hour a day of use). Having the ability to communicate via RS485 or other technology would be even better, to be able to control amperage via programming, or disable the chargeverter entirely. Not sure if it'd be integratable with the EG4 LiFePOWER4 Communications Hub but that seems like the best option to be. Being able to have it show up in a CerboGX via the hub seems like it would be the creme de la creme.
