about 6 monyhs ago began installation of 18K pv inverter with 4 eg4 48 volt batteries, grid tied and connected to wifi. Had to leave for a few months. While I was gone, I'm sure the grid went down once or twice. I am here again and I find I am unable to connect to the system via wifi - al I get is 1 steady light and one blinking light on the dongle, all the batteries are showing the red alarm light ( even though the voltage reads 42.6) and the batteries don't appear to be charging. Before I begin to start messing with the system - any comments about what could have caused this to occur. Prior to leaving the batteries were staying charged, all green leds on them, the wifi dongle worked, I was exporting excess power to the grid ( believe I still am, but cannot verify)

Not sure what happened but if I try using the dongle to connect to my iPhone. I have to unplug the dongle and turn my WiFi off on my phone. Then I plug the dongle into the 18k and turn my WiFi back on. I have to do this every time I connect. Try unplugging the dongle for 30 seconds then plug it back in to connect

The Wi-Fi dongle troubleshooting guide may help you reconnect the dongle: Wi-Fi Dongle Troubleshooting Guide. Although, I would power cycle the local router and remove the Wi-Fi dongle from the inverter for 30 seconds to see if connection is restored.
For the battery alarm state, this is likely due to the battery voltage levels. Module voltage protection may activate at levels as high as 44.8V, depending on the battery model, and may require a separate battery charger to wake up the cells. Try setting the AC charge to a low amperage (10A) to see if the batteries start charging. If you can export the settings or provide the inverter's serial number through DM once the connection is restored to the monitoring system, I can review the details to help determine why the batteries discharged this low.
