I saw a video on Youtube where a guy ran a Pure wave DC inverter and a Honda 2000 parallel. (if you search far enough you will find it).
he had this setup so he could start his power saw inside his van.
Honda is known to run .2V higher than most other inverter generator and DC to AC inverters. But both will sync AC wave with each other.
when he started up saw the voltage would drop and DC inverter would use some battery to assist in the startup requirements of saw, but once saw motor was up to speed because the output of honda was a little higher voltage than inverter the generator would fully run everything.
