Ive been looking at running the 36v varios 8 on the kracken, but the problem is when it switches to 12 on battery the amperage doubles.

Could you tie two force ports together with diodes so they wouldnt back feed eachother and then when it switches to 12 you wouldnt be overloading the kracken.

Im sure the ground plane is all the same. i would have to get my meter out to test.
 
Yes I understand that but if you use a 24 to 36 v converter that will get you 36, but in the case of switching to battery backup it goes to 12 which doubles amperage. so if you had 2 force ports in parallel it would be enough to say run a varios 8. you could use diodes so one would not back feed the other.

The force ports have a max of 8 amps. That is quite a bit of current.
 
Even if possible, what's your motivation? I don't know the exact power curves for the Varios 8, but if you're in the ballpark of 8 amps @ 24 volts, you're only going to get a few hours run time max on any reasonably sized batteries anyways. A battery-powered bubbler will last much, much longer.

Sorry, misread your post, you aren't trying to run the Varios 8 on battery backup.

I have a 800ah battery bank thats hooked up to the hydros, I had a customer that had me replace the batteries in his boat and they old ones were still good. it would run that pump for quite a while at 12v along with the wave engine, So my worry is when it switches to 12v it doubles the amperage, yes this pump wouldn't be running at 100% but just thinking hypothetically, i guess I could use the 0-10v port to slow it down in case of the low power mode?

I did hear they may be a mod that the battery backup can be 24? use a step up converter?

Im a marine electrician by trade and do a lot of re-wires of large vessels so I'm just thinking outside the box.

I'm currently running a slew of 4/0 cable to run some serious amperage of some inverters.

Appreciate all your guys input!
 
Doubling up and using 2 force ports for more current wouldnt give you much, since you would then hit the MAX limit on the battery port of 10A pretty quick. There is a 10A fuse on the battery cable. And do not replace that fuse with a larger once since the internal circuitry is limited at 10A.
