But at times older products with motors will cause the afci breaker to trip.

Solar panel circuit breaker keeps tripping.

Should be at least 25a breaker. The circuit breaker trips when too much electricity flows through it or when it cannot handle the excess current load. The solar pv circuit breaker in the electrical switchboard has tripped twice now in the last few days. Hours before they will trip which is probably why you are only seeing it occasionally now.
