Eftakher Posted September 23 Share Posted September 23 My batteries went under voltage cut-off, and my Growatt SPF 5000ES stopped charging them. I changed the settings from LI to US2, and it started charging, moving from 24% to 25%. However, now it’s stuck at 25% and won’t go higher. What can I do? I am very new to solar Quote Link to comment Share on other sites More sharing options...

GMAC Posted September 24 Share Posted September 24 (edited) If you changed from LI to USER then you have to setup the bulk and float parameters to suit your batterys . So more info on lithium installed or cells used will be helpful Edited September 24 by GMAC Quote Link to comment Share on other sites More sharing options...
