Our system is a Kodak 7.2 with Hubble 5Kw battery and 6 Canadian 550w panels. It is set to SUB.
The problem is that when the load is increased (still less than 50%), the inverter switches off the mains supply (LED bar turns white) with switch in the Kodak 7.2 jittering (for a second or so). It stays in this condition for about a minute or more before switching back to the mains supply. During the jitter the house lights also blink a few times.
Is it possible that the Kodak 7.2 is not set up correctly?
Thank you.
