It's a way to run stuff off battery without setting up your own system. Similar to your system but the kraken will shut off most items during power outage and drops the current so the battery lasts longer.What’s the advantage of the kraken? I can’t see any value in that particular piece. What’s it actually do? I run 12 and 24 volt pumps right off of battery’s directly. Solar charges the battery’s, generator kicks in if needed. My pumps are minn kota brand trolling motors If that matters. i currently have the hydros sense module for monitoring only usage
