When solar panels are fully charged and the battery is full, the controller opens the circuit (creating a pulsing on/off pattern that is invisible to the human eye), preventing damage to the panels; the claim that oversized solar arrays harm panels when batteries are full is false.

Evidence Quote

they're going to open the circuit that's all it does... your controller constantly opens and closes that circuit all the time it's like it's called pulsing
