Great news Twizzel. For future reference you can get alarm units to tell you if there is a power cut. They are quite loud and certainly woke me up several times during our hatching in the Dordogne, where the power supply is chronically unreliable. We had a large leasure battery and 300W inverter standing by to power the incubator, which we also used when we went out. The battery would keep our incubator going for over 12 hours- plenty of time to set up the generator.
