  • JK BMS no longer showing up on device list

    I recently replaced the two Daly BMS on my 48v lifepo4 battery banks with units from JK. They've been running fine for the last few days but this morning I noticed that only one of the two is showing up under the device list in the JK app. The led on the BMS is on and it seems to be working...

  • CCGX Reporting Negative Wattage

    From time to time I'll look at my CCGX in the evening after the sun has gone down and notice that the home screen reports negative wattage, usually -11 to -16w, in the PV box. When I look at the data from the two SCCs either through the CCGX or using VictronConnect, they both show 0W. Any thoughts?
