Hi All I have 3 Narada NPFC 100 batteries and an Axpert 5KVA Inverter. My supplier advised me to connect them each directly to a busbar. Which I did. I don't know what the right float charge setting (setting 27) must be. The manual says float voltage 54V; full Charge is 54.5V. But my supplier gave me a document saying float charge voltage must be 51.2V, they normaly install cell towers with the bateries as backup. I don't have utility back up and don't need the generator (I have been living of the grid with AGM batteries before for 8 years). I dont have a RS485 input point on my inverter. Other settings that I use that might be relevant 1) SBU 2) Charge Current 60A 5) USE 13) 51V 16) SnU 26) 54.5V . So what should I program setting 27 at? 51.2V or 54V? Great Forum got a lot of my questions answered here before. Thanks
