Solar Panel Disconnect Box

The dc disconnect is used to interrupt the dc current from the solar panels to the inverter in the event of a power surge.

Solar panel disconnect box.

In fact the national electric code nec section 690 15 requires arrays to have a disconnecting means to isolate the inverter from the pv power source. I have everything wired together junction box at the array dc disconnect inverter ac disconnect and revenue grade meter the idea was to do the scary stuff tomorrow. In a solar pv system the ac disconnect is usually mounted to the wall between the inverter and utility meter. The ac disconnect is used to separate the inverter from the electrical grid.

A dc disconnect shuts off the current from the panels to the inverter. The second disconnect is the ac disconnect. Additionally the ul listed 600 vdc per pole and 1000 vdc bi directional disconnects are available in 30a 400a for grounded and ungrounded pv systems. Typically there are two disconnect boxes in any given system one for the dc connection and one for the ac connection.

Eaton s solar disconnects provide the best solution for switching solar photovoltaic pv circuits as they directly convert the sun s light into electricity providing power during daylight hours. The dc connection is wired between the source of energy in this case the solar panels and your inverter. An ac disconnect shuts off the current between the inverter and the ac power grid. Utility companies may also utilize the solar disconnect when performing maintenance or other repairs to nearby power lines.
