I needed to test the RSD/ESS buttons. I received unexpected results and need to know if I am incorrect.
The RSD is connected between the main FB 21 and the GB. I disconnected the external switch, but when it was connected, saw the same results. The house is connected to the back up ports in the GB
Before the test everything is running from the array and batteries.
Without the grid connected, everything shuts down.
with the grid connected the array and batteries shut down the grid comes on and off and on and off Cycling power to the house and the inverters.
Cycling power to the house and the inverters.
I was under the impression that the back up would shut down. I also am wondering why the inverters are being back fed from the grid.
I also am wondering why the inverters are being back fed from the grid But perhaps they should be, but I wouldn’t expect them to cycle.
but perhaps they should be but I wouldn’t expect them to cycle.
Does anybody have any thoughts? Is there something wrong with my GB?
Please let me know
