Hey everybody,
I just set up my first small solar system. 2x200W panels, a 24V LiFePo4 battery (29,2V fully charged) and a Victron 100/20 charging controller. Now I'm a bit worried because of a strange behavior - when it's sunny the 100/20 controller shows the battery charging for a minute, at let's say a voltage of 28V and then suddenly the battery voltage shows 33V and the charging stops. Then suddenly it's back to 28V, charging again, and this cycle keeps repeating.
FIY: The controller is of course set to LiFePo4, 24V.
So might this be the controller's fault or the battery? And do I have to be worried something might blow up?
