Abstract
In one embodiment, a solar power inverter includes at least one component associated with conversion of direct current (DC) from one or more photovoltaic cells to alternating current (AC). The component is electrically coupleable to an electrical conductor configured to carry electrical current. The solar power inverter also includes a first surge protective device (SPD) electrically coupled to the component and electrically coupleable to the electrical conductor. The solar power inverter also includes a second SPD electrically coupled in parallel with the first SPD and electrically coupleable to the electrical conductor. As described in more detail herein, the first SPD is configured to actuate in response to a voltage surge on the electrical conductor before the second SPD.
