Power on start up

thumbsup

Any info you can share WRT that?

Could use a device like this:

will this fit in the emonpi enclosure?

I think it is fairly clear that neither of those units (posts 22 & 23) will fit inside the emonPi.

no post 21. i know the cyberpower won’t; it is an external ups.

this will be my 1st rpi.

This may or may not be an issue, but be aware the Cyberpower UPS output isn’t a sine wave.

From the description on the seller’s page:
Uses pulse wave modulation to generate a stepped, approximated sine wave to supply cost-effective battery backup power for equipment that does not require sine wave output.

Although it’s rated at 1000VA, and the load you’ll be putting on it is considerably less than that, you might find the amount of battery powered run-time may not be as much as you’d like.

thanks for the perspective bill. i’m not using this for anything critical. i have used a cyberpower ups for several years now without issue. since these are only $30 including shipping, it seemed quite a bargain.

Gotta admit, the price is right.

we will see - if it ever ships.
