Hi,
I have a Solax x1 hyvbrid inverter and 4 X 3.1 KWH batteries. The maximum charge in the menu is set to 80% (advanced settings)
As you can see on the graph, the battery charged from solar and reached 80% at +/- 7.50 and stopped charging. However at 8.20 the soc curve started to go up again all the way to 99%. The funny thing is that there was no increase in battery power (dark blue area) nor was there any draw from the grid (red area). I would be grateful if someone coiuld explain this.![power graph.jpg power graph.jpg](https://diysolarforum.com/data/attachments/154/154993-2a47c0e7bd31acbd0be206f467aecc49.jpg)
