Battery Backup

Recommended Posts

Any use a battery backup for their tank? I am not finding anything designed specifically for this, outside of individual power head backups.  Thinking about just using the same as I use for my network gear, an APC UPS. Just putting feelers out to see if anyone has had experience or a good solution. I have access to generators for longer term outages, mostly looking for something that will run a DC return pump for a couple days.

I went with this:

With everything plugged into it (heater, pumps, lights, etc), it lasts 1-2 hours (can probably get it to last longer if just the pumps and heater are going).  Anything longer than that I switch to the generator for the whole house.

I will likely do the same as I’m just not finding anything designed for the hobby.

If you have an Apex, it can be integrated with a UPS battery to detect when there’s a power failure and turn off high-powered devices to preserve the battery life for water movement.  It can also send you an alert about the power.

I explained how to do this in my tutorial on Apex Power Monitoring:

Awesome I will check it out for sure!   I did order an Apex for this build this go around.  Exciting to see how far monitoring and automation have come in the last 12 years since I took a break from the hobby.  I am a total tech nerd, so all very appealing.

I have the icecap one plugged into my dual gyres. Works great and the newer gyres recognize the power out and switch the pumps into only running a single to conserve. Overall happy with the piece of mind. Haven’t had to put it to much test aside from a maybe 3 hour outage.

I was looking into those, but they don't have enough power as I want to keep the Apex up and running too.

Do you frequently lose power? Because running the apex on a UPS isn’t going to last very long and doesn’t have a ton of point IMO. Apex will already contact you with the heartbeat if it disconnects for more than 30 mins so if it’s just for notification sake it doesn’t really matter.

 

I have seen people buy a used UPS and wire it to a deep cycle battery for some real significant run time, if you feel up to that, it would probably be the most ideal route.

I would think the power used by the controller itself is not massive, minimal at best. Maybe @SuncrestReef has a ballpark?  Otherwise I’ll just test it when it arrives. I often work an hour away from home, so the idea of having control in a power outage is enticing, plus automation when the power goes out. With a DC return pump, the ability to dial that back for maximum runtime seems like a good idea in theory.  
 

I run all ubiquiti gear in a rack with an APC 1500, and I get a couple hours out of it during an outage(more if I start turning down cameras and AP’s) That’s a UDM Pro, 16 port POE switch, modem, and anything fed via POE switch. We just moved out here in August, no power outages yet, but I’m a firm believer in plan for the worst and hope for the best.  When we lived in SE PDX we lost power a few times every winter or wind storm. I have an extra APC 1500 that’s not being used for anything important, so I’ll just move it over. 
 

I’ll just have to send it through a test run when the tank is cycling to get an idea. Trust but verify.

Hi John,

I was looking at your diagram on this tutorial and noticed you have the Apex plugged into a wall outlet using the Auxiliary Power Adapter - wouldn't it be powered off in the event of a power outage (since it's not plugged into the UPS)?  Or will it still get power from the Aquabus line from the EB832?  Thanks!

If you read the tutorial carefully, I explain that the aux power adapter is how the Apex detects when the power fails.  The aux adapter is an optional component purchased separately because the Apex is normally powered through the AquaBus cable plugged into the EnergyBar.  In this configuration, the EnergyBar is plugged into the UPS battery, so when the power goes out the EnergyBar still has power, but the Aux power adapter goes dead, so the Apex knows there’s a power outage.

Think of it this way:  the aux power adapter is not being used to power the Apex, but instead acting as a sensor.

One more note about the Aux power adapter: It can be used to power the Apex base unit if you don’t own an EnergyBar.  In this configuration the Apex would only be used to monitor an aquarium, but not actually control any devices.
