Due to poor local electrical reticulation and frequent power cuts, my system, along with lights, runs from an inverter which is powered from PV panels, the incoming mains and has batteries. The inverter can supply up to 8000VA
At about 5.30 in the afternoon in winter here, the inverter switches over to "bypass" mode where it stops generating power from the PV panels and switches to the incoming mains, if it is present
This changeover takes 2ms and sometimes, but not always you can see the lights flicker, if they are on. The inverter supplies 230 volts at exactly 50Hz. The incoming mains can be anywhere between 210 and 245 volts and often the frequency will dip to 48-49Hz
At this point, the amplifier switches itself off immediately
The computer carries on as usual. It is a desktop and runs off the mains
