Good Morning All. @Coulomb This thread seems to be the closest I can find to a similar problem I am having. Previous Setup: 12 280ah 12V Gel - 4 batteries wired together into 3 banks connected to bus bar, connected to 5Kva Mecer SOL AX Inverter. 6 x 600W PV Wired in 2 banks of 3 panels each. The system was set as SBU (Solar | Battery | Utility) AGn for Battery Type 54.6V Max Charge with a 46V Cutoff to change over to Utl (Utility) The system was working perfectly with the invertor automatically switching over to Utl when batteries are discharged and switching back to the invertor when the sun came up. I recently upgraded my battery to a 9.2Kva FiveStar Lithium. Settings that were changed: 05 Battery Type from Agm to USE (User Defined) [12] Point Back Voltage to Utl 46v [13] Point Back Voltage to Battery 54v The issue I am having now is when the sun has set and the load is on Battery and batteries reach their cutoff voltage, the invertor no longer changes over to Utility supply, nor does it switch back to invertor the next morning. I am no electrical expert in this matter, but think I can follow manuals and instructions pretty well. I hope I am just being an idiot and have a simple setting I need to change. Any assistance in this matter would be greatly appreciated. Thank you kindly Ty
