Hello guys I am having some issues with the EG4 6500 inverter after doing the firmware update. I purchased the inverter back in apr 2023 and I have now did my first firmware update about a month ago because I noticed my led lights would dim in and out as the sun came up and started charging the batteries so I did the update which I regret now. I had my settings where only solar could charge the batteries and I am in SBU mode; putting solar as priority, then battery and then utility when it hit low voltage. So I ended up having a couple of cloudy days in Texas that ran down the battery and the inverter went into bypass mode when it hit 46v in the settings. But when the sun came out again and it was bright and sunny outside, it would not get out of bypass mode nor would it recognize the batteries to charge them. I called signature solar and went through some trouble shooting steps and still nothing. It did this for days until it miraculously read the batteries and started charging them again and switched out of bypass mode. I have 8 battle born batteries connected in a way to make a 48v system (The batteries were balanced before connecting them). When it was stuck in bypass mode I checked the voltage on the batteries and it read around 45.4v so the batteries themselves did not discharge nor were the batteries being charged by the inverter. One thing I did notice is that I had settings 12 (Setting voltage point back to utility source when...) and 29 (Low DC cut-off voltage) set as both 46v. So I adjusted the settings and changed settings 29 to 45v and kept setting 12 the same ;46v. I also changed it to where utility can charge the batteries as well by changing settings 16 to C50 . Now I'm just waiting to see if anything changes. It sucks that I don't have a 48v battery charger. I only have 12v battery charger. I was hoping that I would have a system I can sit and forget except for yearly maintenance such as battery balancing but the new update seemed to mess things up. It is currently stuck in bypass mode beeping b4 error and occasionally 04 error. It's not charging batteries even with the change of settings. Do anyone know why it would do this?
ALSO do anyone have a link to the old eg4 6500 firmware ?
