- Page 5 1. Solar photovoltaic circuit breaker The solar photovoltaic circuit breaker with reclosing function could be automatically opened in the case of over-volt- age and under-voltage, and it could be automatically closed when the normal voltage is restored. At present, there are several main scenarios: one is a distributed grid-connected system, and another is a system with large grid-connected scale.
