Thanks, it's a great battery. I reported someone selling stolen Averge batteries to them and they offered to sell one to me directly.

Thought I would share a "fix" I have found for this issue.
I have the Synapse King 5w inverter and it does the exact same thing when in SUB mode - it would work 100% fine and utilize all the available solar power for days on end and then all of a sudden for no apparent reason it will stop using solar for the load and only use about 50-60watt to keep the battery full. Once this happens it is stuck in this condition and it seems like there is nothing you can do to get it to work again. If you switch off utility power it immediately uses all available solar power, but the minute you switch utility back on it drops down to 50-60watt again.
The only way I have found to get back to normal operation again is to do a factory reset on the inverter settings and then enter the exact same settings you had before. As soon as I do the reset and change output priority to SUB, it starts working as it should again, every time.
