Hello I have a hybrid 3.5kw fivestar inverter and a 2.56kw fivestar wall mounted battery Lithium Pos4 with 3 panels generating 1200w of power. I have a flashing icon on my inverter that gives me an error ALR 245 = bms comms failure. Does anyone know how to clear the error fault. I had the battery set to LIT but noticed that it was not charging. I reset the inverter to the factory settings and the battery charged but still has the error as described above. Any help will be appreciated.

Hi bud did you ever get an answer here ? 

I need some help please. I have a 2 KVA PWM 1500W fivestar 12V Solar Hybrid Inverter.  With a 50Ah lithium battery and one solar panel.  I only get 1hr and 30min running time during LS. I'm only running a small TV, wifi and a light. Load says 6%.  The settings are so confusing. I keep getting at low voltage battery error and ALA 235 error. Please help surely I should be getting more time than this.. what settings do I change ?  

My issue corrected itself. Once I picked the right battery type and let it charge full it somehow no longer had the BMS error. I think the battery itself has a BMS plus the inverter has its own BMS settings so they were conflicting. 
 

based upon your usage you should be getting more LS time. I think on the same setup with cameras etc running I get between 6-8hrs. Have not run it completely down.
