these can NEVER be unplugged or plugged in while the sun is on the panels. I've done a lot connecting and disconnecting MC-4 panels under often bright sunlight and I've never noticed any problems though this has been with. . is it safe to unplug the MC4 Connector just after opening the circuit at the inverter level (unplugging String's DC wires from the inverter ) ? If you have RSD, you can turn that on and suddenly there's no current (theoretically, still test). If you don't have RSD, you'll have to cycle the inverter. . Before starting the disconnection process, shut off the DC and AC circuit breakers so there's no electrical load connected to the solar panels. Turn Off DC and AC Disconnect Switches The first. . Working with solar photovoltaic (PV) systems requires recognizing that the panels generate power any time they are exposed to sunlight, meaning the system is always “live” during the day. Let me guess you don't have one. How Much Do Solar Panels Cost? - How Can I Get A Quote From An Installer? - Register to Post DC Arc welding. The. .
