What is a PV inverter?
An inverter is an electronic device that can transform a direct current (DC) into alternating current (AC) at a given voltage and frequency. PV inverters use semiconductor devices to transform the DC power into controlled AC power by using Pulse Width Modulation (PWM) switching.
How do I switch off a DC inverter?
Firstly, you need to switch off the inverter using the isolators adjacent to it. Click the video to the right to show this process. Switch off the a.c. isolator first (red handle) then the d.c. isolator (s) (black handle). On some installations the d.c. isolator is built into the inverter (on the underside next to the d.c. connections).
