Question re your battery bank. According to the Growatt 48V SPF 3000TL LVM manual, it seems to say the that you can choose between AGM & FLD for the battery or if using lithium it seems to indicate you need to use a Growatt battery. It does not indicate settings for a generic LiFePO4 bank. Did you do anything special to set up for your batteries?
My SPF 3000TL LVM just arrived today and my 48v bank aint Growatt.
