Question on the 6105 and battery backup

areefer01 · Aug 18, 2025

Are there any best practices or guidelines on the best way to put a Tunze 6105 on a Ecoflow Delta 2? I may be over thinking this but I was trying to see if there is any option to use the Ecoflow DC ports as a direct connect rather than using AC outlets. Thus saving on any AC to DC conversion loss.

It may not matter but looking at options to both test, and extend, battery life while on vacation or if power is disrupted for several days (Godzilla walking through the neighborhood). Traveling is picking up so trying to optimize what I can.

I know there is the Tunze safety connection but I am not sure how that is used or if it would apply in this use case. If there is an example please let me know as I very well may be thinking about this incorrectly.

Thanks!

I don't see any way to bypass the conversion losses with the Ecoflow. Generally speaking, the pumps alone can get you through some hours, maybe a day without power but in most cases after that temperature and light become issues and there are no practical backups there besides a generator so there is not much point to going overboard on battery back up systems, 8-24 hours is about all that is likely to sustain the tank for unless you are very lucky with regards to the temperatures when it happens.

I do not have a Delta 2 but a River 2. I hook up the safety connector to the DC port on the Ecoflow.

Thank you both. @rvitko correct on the heat and light. I can do without the lights so not too concerned unless it is 2 or more days. Heat is another one for sure. I am just trying to address the flow and to see how long I can manage it.

Thank you for the video. let me look at that as my search on YouTube didn't return that one. Appreciate you!
