Good luck with your upgrade. We ordered our '22 310RL in June of 2021 with the factory-installed Renogy solar package, which included the Progressive Industries 2K inverter. The inverter works fine, but we cannot do much with it other than run our refrigerator for the most part. I'm slowly upgrading my solar setup to all Victron. Still have to purchase and install my
MultiPlus-II 2x 120V and add a few more panels on the roof, then I'll be done...for now. I love how that Victron MultiPlus unit will balance out your voltage by pulling from batteries if you are plugged in and your input voltage dips. At least that is what the advertising video/literature says.
