Hi guys, I'm looking to upgrade my solar system with Victron. I'm currently grid connected and want to stay that way. I have a hybrid sungrow inverter/charger with back up. I'd like to add two multiplus 48v 5000. Can I add these and keep my sungrow? Or do I need a differnet inverter or solar charger? If I do need to change from my sungrow, how does the multplug dis-connect from the grid and run everything in my house. It appears to me that the multiplus can only run critical loads when the grid goes down? Sorry for all the questions. Thanks in advance.
