I have a Givenergy All In One System, and having seen the references to Wonder Watt I registered and signed up for the system. Last night I set Wonder Watt to charge my battery between 02:30 and 06:30. I got up for the loo about 4am ( I'm old! ) and saw that the battery hadn't started to charge. I opened the Givenergy app and using the Quick Control dashboard told it to start charging. After a short time it switched to charge. I double checked a few minutes later and saw that it had stopped charging so I went to the Web Portal, " My Inverter " and saw that it had reverted to " ECO " From there I set it charge and away it went. Shortly it reverted to Eco and stopped charging. Looking at it again I saw that the setting was to charge to 15%, as the battery was above this level that explained why it had stopped charging. I set it to charge at 100% and away it went, before reverting to ECO and looking at the settings " Charge to 15% had been reenabled.
As a new user I'm aware that it is probably something I'm doing wrong. I have Predictive Smart Charging switched off. I'd be grateful if someone would point me in the right direction.
