Hi, I noticed today that my PV had a production of around 150w and was only charging the battery woth 20w. So the produced energy disappeared……at the same time my hyper + batteries made a high pitched noise. After turning off and on of the hyper the PV production went again to the battery as should. Has someone noticed the same problem. See also the graph which shows the suddenly dropping of the charging of the battery and the disappearing production.
