Two weeks ago I bought an EG4 6000EX0HV, and TWO EGL4 LL V2 batteries. I had everything hooked up and running. I resolved the dreaded error 61, and even ran some light 120V loads via a power strip. However, today, when went to power up the system, and pushed the “on” button, my #1 battery did NOTHING. NO status lights, and NO LED screen. I did flip on the #1 breaker, and had 55-56 volts at the connectors per multimeter. #2 battery powered up totally fine with all lights and screen. Inverter “sees” battery #1, and confirms good voltage, but no combination of hitting “reset”, or even disconnecting and reconnecting all wires can bring my status lights or screen back to life. Interestingly, #1 battery by itself WILL power the inverter, even though no lights or screen. I am now also back to getting the incessant error 61 beep. The manual is worthless. ??? Has anyone else had this problem, and if so, was there a solution???? I have sent an email to Sig Solar, but with it being Sunday, am not expecting any response today. Any help or suggestions would certainly be greatly appreciated. I am very disappointed to have had this kind of problem with a two week old system. Thanks, Tom
