UPS Battery Backup

I preformed a test today. Killed the main breaker to the entire house as a test to see how the wifi router, start9 and all my miners would react. I’m glad I did as I identified problems with the miners, wifi address with the providers modem and start9.

First. - I noticed several of the local network IP’s never came back online. 2 out of 5 miners needed to be setup from scratch with new ip’s. That was interesting.

Second - some of the services on the start9 needed to be stopped, restarted to sync. Namely Datum, LND and Alby

So - it looks like I need some type of UPS backup (pure sine I imagine) for the Start9 and the XFii modem. Since I have a surge protector power bar mounted in a mini rack that contains all the miners that I have I cant string surge protector devices together so I’m thinking another UPC without surge protection for the miners.

What you think folks. Any experience with UPC? How about @paul …any expereince?

Coincidentally, I happen to be working on a video series related to this. The first one will be reviewing a particular model that is widely available and on the lower-end as far as cost. My ultimate goal will be to see if I can hook into the USB callback interface to have it run a script that shuts down the connected server. I hadn’t considered also throwing ASICs into the mix, but that would be good to add as well.

This is the UPS model I’m testing with (ignore the wifi router)

Yep.I looked at that one for sure. Would need two as server/wifi to far from miners.

Is the 360 watts…is that constant power just plugged in?? That is as much as 3 Nano S3’s on high (18 Th/s). :crazy_face:

Good point – ASICs are going to be a problem for a lower-rated device like this one (I was origionally looking at this from just the minPC + router perspective). The 360 watts is constant power when running off the battery. Basically, the APC guarantees the inverter can source ~360 W of real power for the entirety of the discharge curve (until the “low-battery” cutoff) at 25 °C ambient. The batteries will be exhausted in ~3 min at that load, but the inverter will not trip on over-temperature or current-limit as long as you stay at or below 360 W.

Ah roger. Make since that is the draw load in backup mode. Thanks for the clarity. Had me a bit worried if I need to buy stock in Xcel to offset my energy costs :wink:

I’d have to recreate the IP problem to get a better understanding of the issue there. My initial thought would be to configure all of the routers to reserve specific local IPs based on each device’s mac address. That way when the routers come back up and devices start to connect, it doesn’t just hand out IPs willy-nilly.
