The inverter will want to attempt the start multiple times before giving up. I’d like to do the same and then switch to starting the second generator after maybe 3 failed attempts at starting Gen 1. It seems I need to code some kind of script to execute this logic. This is where the Control by Web solution seems to be the best fit.
