Posted March 17, 20232 yr Good morning People. First time poster here. I have a Fivestar 3kva pwm inverter connected to 2 x 12V 200aH Fivestar batteries connected in series. The inverter does not have a specific setting for Lithium batteries. According to the battery manual it should be charged to: Bulk/Boost phase: 13.8 and Absorption Phase: 14.4V. On the inverter the following settings are available: Bulk charging voltage (C.V voltage), and Floating charge voltage. My confusion is now, which one is which on the inverter? Do I set the Bulk charging voltage on the inverter to 14.4v (x2) and the floating charge to 13.8v (x2)? Thanks. Edited March 17, 20232 yr by WinterRSA Formatting

If other members don't respond you will have to try settings of 13.8 and 14.4V and see it is does charge. If not then use 27.6 and 28.8V
January 16, 20241 yr Good day. I have the same issue. I have a 3KW, 24V Fivestar inverter. It seems if the inverter have reseted all its settings. All battery settings are limited for 12v only. This reault that my batteries does not fully charge. I changed the battery type to user, but still setting 6-10 is limmited to 12v. I would appreciate any advice.
