I am confused ... I want to do a simple (all in one) 24V system . Looking at the Growatt 24V 3000LVM, using a Rack Battery 200ah, 5Kwh. LiFePos. I need help to understand the Solar panels I need. 12v or 24v panels. Series or parallel? I am terrified of purchasing the wrong panels and over loading the system. Any guideance would be a blessing and a huge help.
