I recently set up a Kraken with a lead-acid battery to provide battery backup power during power outages. I did a test where I unplugged my equipment from the wall and none of my equipment connected to Kraken turned on. I also had a hard time getting equipment to come back on after plugging back into the wall. I finally was able to get it to reset after unplugging the 12V battery line from the Kraken and unplugging from the wall. Then plug into the wall, let it start up, then plug the 12V battery line back into the Kraken. Are there any extra setup steps I need to do in the app to program Kraken to power certain ports on battery power mode?

Do you have a low power mode setup? also make sure that any outputs you want to stay on are set to active in low power mode. Also remember that the force ports will only have 12v on them in low power mode since the battery is only 12v. Some devices will not work with just 12v instead of 24v. Also make sure you set which mode is low power in your options menu.
No I do not have a low power mode set up. Is that created like any other mode? Do I just need to name it "Low Power"?

You can name it differently but you have to tell the collective which one is low power mode in the options menu.
I see it now. I need to configure that. Thanks!
I have created a mode for lower power and assigned it in the options, but when I try to test it by unplugging the Kraken and XP8 from power, my DC devices still don't operate from battery. Now that I have configured a Low Power Mode, my XP8 just starts flashing red and an alarm sounds.

Do you have the outputs you want on set to active in the low power mode. Also the force ports will only output 12v in low power mode and not the normal 24v. Some devices ill not run with only 12v supplied to them.

I just tried mine and it shows 12v on the force ports that are suppose to be on when in low power mode. Also you should be able to connect with it on the app when it low power mode as long as your wifi and internet are still working. In a simulation test they should still be working.

On a Wave Engine it might run at a lower flow rate on 12v, but you would have to have a schedule for low power mode and set it to be active during low power and have any other schedules for the pump inactive in low power mode. Not sure if the actual Various controller will run at 12v.

So Kraken would provide full power to its own drive ports and half to force ports, as well as, rest of the collective devices and all their ports aside from outlets on XP8? And as long as those outputs all set to run in low power mode they should be active?
Also what are you seeing as far as some sort of run time, I don't really have a good feel for how much run time amp hour would provide really, especially how much collective itself might use.

The battery backup does keep the other Hydros device on, but you are right the 120v outlets on the XP8 won't work. I have not done a long run on battery power mode, just a ops check. One way that is a little easier to estimate battery backup is multiply available amp hours by voltage to get watt hours. A lot of equipment will tell you how many watts it uses. But you have to also keep in consideration the equipment will not run once the battery voltage dips too low after a long discharge.

Yeah I would probably not run too much. Likely just one of the gyres in the display to keep things going till someone can attend to the situation in a bit more manual manner.
I have a 6KWh bank of batteries from EcoFlow that I can power few selected circuits with, but I have to be home to flip the switches. And more long term pull out generator or solar panels to charge them.
I normally use computer UPS, but those do not last whole lot plus waste energy going from dc to ac to dc and battery in ones I use looks like is only 9ah, so this would be likely better solution and can get something like 100ah battery, which probably should last a day running a gyre and collective, if I'm guestimating things correctly
As far as detecting low power, do you still need to use 0-10v thing or kraken has that internally now?

Once you have the low power mode setup and the command bus power drops from the normal 24v to 12v the controllers sense this and go into low power mode. I think all it takes is one to sense it for it to trigger a low power mode. I have several in the garage and if I power down one side it will cause the collective to go into low power mode.Yeah I would probably not run too much.

@Raiden I just purchased the Kraken, I created a post here that hasnt been approved, and its going on 1 week. Admins???
My question to you is:
I have the specified recommended battery as you, does the kraken have a monitor mode to check battery status like full? empty? etc... Also does the trickle charge stop after a while? More curious to know what all features does it display when a battery is plugged in?

This is the only thing you get. You can work out % from voltage, but nothing is provided in UI. It does seem to stop or at least really slow down charging once it thinks the battery is full, which is also voltage driven.
