Disconnecting Solar Panels Under Load

A tested and approved safety device which removes all lethal dc volts from any solar installation.

Disconnecting solar panels under load.

Common issues are zero power and low voltage output. Often overlooked connectors are important to maintaining relia. This article describes how you can troubleshoot a solar system in basic steps. In a solar pv system the ac disconnect is usually mounted to the wall between the inverter and utility meter.

Can be installed on a new system or retrofitted on any exi. The ac disconnect is used to separate the inverter from the electrical grid. Troubleshooting a solar pv system below i will describe basic steps in troubleshooting a pv array. Quality solar panels are built and guaranteed to produce power for 25 years for that reason it s most likely that a problem is caused by a defect in system.

The ac disconnect may be a breaker on a service panel or it may be a stand alone switch. Utility companies may also utilize the solar disconnect when performing maintenance or other repairs to nearby power lines. Applying the factor by dividing the maximum power point current by the factor will show how the disconnect switch should be rated under normal conditions. In this next video installment in the solar basics series we will take a look at connectors.

Step 4 cover the ends of each wire with electrical tape a plastic bag or a rubber terminal cover to prevent physical contact should the wires become live. Some larger systems use a solar power disconnect switch for added safety in case one of the solar panels gets exposed to light during maintenance. An ac disconnect shuts off the current between the inverter and the ac power grid.
