6 FAQs about [Photovoltaic power station inverter shutdown]

How does a solar inverter shutdown work?

When the shutdown button is pressed, the inverter disconnects from the utility grid and stops both the output and input from PV arrays. This helps mitigate damage from hazards and ensures the safety of the entire solar system and the stability of the utility grid.

How do you turn off a solar inverter?

Locate the AC ISOLATOR main switch and turn the switch to the OFF position. Alternatively, go to your fuse board, locate the PV ARRAY main switch, and flick to the OFF position. At the inverter, locate the DC ISOLATOR and turn to the OFF position. If there is a battery fitted, locate the 2nd DC ISOLATOR, and turn to the OFF position.

Why do solar inverters shut down during a power failure?

Solar inverters tied to the grid automatically shut down during a power failure for safety reasons. If there is a power outage in your area or flickers on and off, your inverter will shut down.

How far away should PV inverters be placed?

By placing these smaller inverters within 10′ of the array that they are connected to, the PV system can meet the requirements of 690.12 and shutdown can be initiated upon loss of utility power without any remotely activated switches (see figure 8).

How do I activate the rapid shutdown function?
