Narada NPFC Lithuim Battery Float Voltage

Recommended Posts

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
