The Cor 20 pumps are still 24v they just draw more watts than the eb832 can supply on the 24v 1link port so they require their own power supply.
This is good info to point out as many overlook this!

I am very sorry for your loss. It must be heartbreaking. As a year-in newbie, I read posts like this as potentially inevitable. I've read about too many catastrophic losses not to make preparations. The value of the tangs and Acan's alone justify the added expense.
My two tanks share dual ACFI/GFCI 20a circuits, one side of which is protected by a 3000w auto-switched inverter with 500ah of battery backup (which is also shared with other life support - aka, Apex, router/wifi, my desk, television, etc). Each tank uses redundant cor20 return pumps, 1Link's, FMM's, and heaters. I've recently added bar-type airstones, which are buried under the sand, to the back edge of the tank. These airstone pumps are off unless Apex determines the return pumps are off or have failed for whatever reason, then the airstone pumps kick in. The airline is black and attached to the back corner seam, making it almost invisible. The air pumps take a trivial amount of power compared to a return pump. This, as well as a single heater, one WAV pump, and APEX critical components, get power priority. Being new to the Philadephia area, I'm unsure about outage frequency, so it may have been a sound investment or just plain overkill. In the end, I feel I'm protecting myself from the emotional trauma more than anything.

Eco Flow has several size options and you can even hook up solar panels if you’d like. It’s designed to kick on when the power goes out. You can connect several pumps too. As others have suggested, search telegraham on social media.

There are a lot of players in that arena, but they aren't call UPS. UPS is kind of outdated and often have terrible batteries inside. The Eco Flow kinds of stuff are pretty easy and straighforward and work like a UPS but better and cheaper and longer with a battery that won't burn.
You can get big ones and small ones and often you can add batteries.
I did a system with an "MPP" controller inverter and a 200ah batter that will run the important parts of my system for 8 hours. It runs through the APEX - the APEX and EB832's with the equipment I want to work in an outage are plugged into the MPP so when the power goes out the battery takes over - and it is really nice to have the apex change the flow of pumps during an outage so the battery lasts longer. I have some DC pumps, 14 WAV's, some air pumps, and some AC pumps on the backup. Also, my router and mesh network are on the battery back up. My system now would coss less than 2k, and I am prolly going to double my battery because it will make me feel better, even though I have added solar to the back up system.
Reef Beef Podcast has a couple episodes on this, with Telegraham, if you want some details including a crazy equipment flow chart.

In the incident that prompted me to start this post, it seems the power from the grid to my house went out twice, the second time after I went to sleep. This must have caused the Cor 20 to short out, as it also tripped the breaker for this outlet. The only thing that would have saved me in this circumstance would have been an inline power supply to keep the return pump or powerhead going. I'm looking at the Reefbreeders Coral Box backup (saw this on telegraham's Insta account) in comparison to the VorTech battery backup. Anyone have thoughts on each?

I am also now going to get the EcoFlow DELTA Pro Ultra Whole-Home Backup Power system with 10 x 100W solar panels to back up my whole electrical system. This would not have solved the Cor 20 tripping the breaker, but I am replacing that return pump with the Vectra M2 pump, which I've heard is far superior in terms of longevity and performance. Have to do whatever is necessary to never have this happen again.

I don't know about far superior but the Vectra it is a quality pump. I am running 2 x Cor 15's and 1 x Cor 20 since they became available in 2018. That is a lot of years. I did have to replace the Cor 20's power supply a couple years back but other than that they work great for me.
I think what you are doing by examining power in your home is wise. In fact it is something all of us should do as part of our design regardless of gear. Reefs take years to mature but can be lost in a couple of hours sadly if we do not prepare.

It’s probably already answered, but my bet is the COR 20 is totally fine… the pump part at least. The problem is likely the power brick, if they get turned off/on randomly (power cut) then they can go bad. The voltage error is usually the pump part not getting power but it’s still connected to apex. Could be a simple replacement of the power brick. Sorry if already answered.

just curious what was said by Neptune on the service call. Also, does the COR not come back on at all if you plug it into a normal outlet in the wall? Does it trip the panel if it’s plugged into the wall?
I’m thinking that the power surge from the main line tripped the breaker and not the pump. Either way, the title of the thread is quite misleading.

The Cor 20 can be run as a stand alone pump outside the Apex ecosystem. So yes, if the power was turned back on it should also come back online.
I've seen a volt error once or twice on my Cor's after I turned them off. This typically happens to me after I do have maintenance on the pumps. Disassemble, citric acid bath, scrubbing, reassemble, etc. There is an o-ring that I sometimes don't get set properly and this will trigger it. I've since started using my dive gear o-ring lube which takes care of it. I've also had small snails get lodged inside causing this to happen. Strombus snails get sucked up a lot until I put a screen on the intake (which sadly reduces flow).
TL; DR - yes, Cor 20 can run stand alone and will come back on after power is restored.

Well said. Everything can go in a moment, after years of constant attention and care. Unbelievably, my Cor 20 has just started and seems to be working fine. Maybe it needed a few days off.

Neptune takes forever to get in touch with. I have a scheduled call on Monday now.
See post above. Cor 20 came back on. No clue what happened with the system. I've done huge amounts of electrical work on homes I've built and there can always be something with electrical systems that is utterly confounding.
I'll see if I can change the thread title, as it's garnered huge response.

What a crappy way to lose pets. I’m sorry that happened to you.

Its kinda of a brand or style of but everyone calls them MPP. They are a controller/inverter. This is the one I have.
It controls and charges the battery, has outlets and usb ports built in so no wiring, and can take solar input to charge the battery or run equipment, all basically out of the box. There are other options that take more DIY, and there are newer versions of the one I have.
For fun here is the battery I have
EG4 LifePower4 Lithium Battery | 24V 200AH | Server Rack Battery
The EG4 LifePower4 Lithium Battery 24V 200AH provides reliable energy storage for server racks, ensuring uninterrupted power supply with its efficient and high-capacity lithium technology.

Used to be folks would worry about temperature with power outages, but crashing O2 levels are a much more immediate threat. I bought the exotech battery backup many years ago, so long amortized. Battery lasts about 2 years for me and I just replace it myself. I do have a standby generator on my house, so the battery is back up for the backup,

You meant Ecotech? How long has it run backing up a pump and what pump does it back up? Wattage?
