Does anyone has a GW 3K LVM-ES Inverter with an EG4 48V100AH Battery?
One early morning I have a battery alarm light on (no beep). I think it is OK (unless it beeps) because when the sun goes up and the battery gets charged and then the alarm light goes off. I was panic and I tried to connect my laptop to the battery communication terminal to run the BMS Test to see what happened.

I followed Sig Solar Video on YOUTUBE as well as the Battery User Manual and installed the BMS Test software. I was able to get to Serial CH340 (Com 3) Port and Baud rate 9600 and has Port connect successfully displayed. But then I got NO % Capacity on the “batinfo” display tab. I thought it might be the battery (device) wasn’t connected and was looking for that “Search Device” as shown on Youtube video as well as on Page 14 of the User Manual. That “Search Device” page was nowhere to be found. I have contacted Sig Solar, and the guy I contacted offered no solution. Does anyone successfully done that? Please share how you do that.
