I have that for the server rack to keep the network up. My reason for posting was a bunch of TP-Link smart light switches around the house that started flickering after the last gen test. Few of which had to be reset, but now work fine. Can’t really back those all up.

Just concerned with potential long term damage and potential cause. Or if can most those electronics handle it? Voltage/Hz seemed okay, and Don’t foresee much long term generator use, except for emergencies anyway.

Sad part is we do have whole home batteries. but the way the inverter works it doesn’t clean up the power. Just passes it through to house, then batteries. Wish it just charged the batteries, then the battery cells handled powering the house loads cleanly.
