is there a way to run the kracken on 24v off the battery backup port so when it goes on low power mode it will still run on 24v?

will it take 24in and put 24v out on the battery side?

No, since the drop to 12v is what triggers low power mode. It also has a built in charger which is only 12v. Also the same thing would happen if you had a ups on a XP8. It would not know there was a power issue since the command bus power would not drop to 12v. You can get 12-24v to 24v DC to DC converters and use them on the devices that require 24v but that is a DIY project.

thanks for the reply, yes I am already using a bunch of converters on the system its great. I have a 450AH Epoch Lithium battery that really does the trick
 
Can you post a link to what converter you might use? I can only find 12v to 24v not any that take both 12 and 24v as input.
 
yeah. now that i was made aware these exist, I found this one here too that now makes me wonder whether I can use it to drive my Syncra SDC9 which only runs at 30%. Need to do more math :)
 
Lets do some math to check it. The pump is drawing 45w (at 30% flow) looking at the XP8 output monitor... so let's be safe and call it 80w through the XP8.
80w/12v = 6.5 A
80w/24v = 3.3 A
So it seems like I should be able to run my return pump with this thing ... oh very excited.
 
We had rolling blackouts several years back that lasted week. The power was out 50% of the time and at time that was over 4 hours off and 4 hours on. I had a AC return pump so it did not run when the power was off. I did have 2 MP10's with battery backup and they were set to run at 6% when there was no power. I did unplug one of the MP10's during the blackouts since I had no idea how long they would last and I did not want to loose flow completely. It ran like this for the whole week without me losing any fish or corals. I now have a SDC 3 and have it powered by the Kraken but that output is not active during low power mode since the pump does not run anyway at 12v. That tank ran with the AC return pump for almost 8 years without any issues during power losses so I left the new return pump working the same way as the old one did.
 
Hey so I’m sorry to ask this question on this thread but its about my Vectra return pump and Kraken. My Vectra pump requires more than 24V to operate, but the battery backup booster they sell inputs 12V and outputs 24V, allowing the pump to run off a battery. My question is: could I cut the end of the booster and the end of the 24V cable your company supplies, then run the battery backup off of the Kraken and set it up so that port activates in the event of a power outage? Or would you recommend buying the appropriate connectors instead?. Now stop me if this has been asked already.

The Kraken force port will output 24v normally but only 12v when on battery backup. There are DC to DC converters that with a inout of 12v or 24v will output 24v. There are post on this forum about using these if that is what you need. They also have them with higher output voltages also.
