Honda advertises their iAVR generators as producing stable enough power to run a computer. For example, see "applications" section at https://powerequipment.honda.com/generators/models/em6500. However, THD, frequency tolerances, etc., aren't listed.

Can anybody here provide measurement-based reasons why or why not it's safe to power sensitive electronics with a honda iAVR generator?

    Used generators to run computer fine, but put a simple load on the genny first so it was running stable then connected the computers...

  • It's always a good idea to put power filtering between any source and sensitive electronics - including computers, TVs, stereo gear,... . Even if the iAVR output is clean, "things" can happen on your house wiring or the grid feed into your house. Oct 1, 2020 at 18:31

  • @dandavis both, plus modem and network equipment Oct 1, 2020 at 21:44
  • @CarlWitthoft, regarding power filtering, would you use a basic power conditioner, like a Furman SS6B, or something more advanced with a "clean power" generator? Oct 1, 2020 at 21:48

The 'promise' of the iAVR generators is that they CAN power sensitive electronics like computers. This is why they cost so much more. If you are concerned, I would put a spike filter and UPS in-between the source and the computer load; it wouldn't have to be a big one. However, the computer has some natural filtering because it uses a an AC to DC power supply which already has filtering on both ends.
