We currently have 27 Trina TSM-295DD05A.05 panels to give us roughly 7kW installed by an installer in 2017. They installed it with an Enphase System M250-60-2LL-S2x micro inverters (27). The roof it's installed on is a Flat roof. At the time, my wife did not want any solar panels on the massive front roof of our home. That front roof faces due west. I can fit roughly 40 Panels on that roof and another 30 panels on our garage roof.
I am looking to set up two more strings of panels, one on the front roof of our house and then one on our garage. Unless you think otherwise, I would go DC rather than AC for this system. I would want to go with Growatt Grid-Tie inverters and have an electrician (my son) connect them to the grid.
I'd like to know if I keep the 27 Panels on micro-inverters or just DC cable them. Any thoughts on that?
I like how Growatt could work for our home, and I've been watching Will's many videos on them. I could also get by with a 6548, but maybe the Growatt is better?
30kW of rack-mount batteries to start with, 48V EG4 . This is in the planning stages, so I'm looking for feedback to see my best options for the current 27 panels and then add up to 30-40 more.
I can also offer up our energy usage if that would help to size the correct system. I'm trying to use the grid as little as possible.
Thank you!
