At AEE we had a very good relationship with MK Battery and I brought in the Deka Duration to sell without really looking at all the potential issues first. However, I did become aware of them after looking at how to install them in detail. I'm curious how anyone does this with multiple batteries. I came up with lots of configurations trying to get around the extreme lack of wiring room in stacked batteries. I ended up doing drawings showing them stacked on their rear end on the floor 3 deep from the wall with a battery combiner on top of each 3 stack. Contact with tech support was always referred to the Italian company and every time I received a very condescending and arrogant response. Then I finally read the warranty in detail, unfortunately after selling some, and having to buy them back. Turns out that at that time (still?) the warranty excluded in entirety any system installed with an inverter that did not have closed loop comms with the battery. Also the temperature range to stay under warranty was basically room temperature only. After discovering all of these issues I decided that we would no longer carry them. I will say that I had no problem getting one to communicate with my XW+ inverter through the gateway CAN bus. The one that I ended up with has certainly worked fine, but of course is not under any warranty, and never has been since put into operation with an open communication inverter in a utility shed that gets down to 40°F.<div><br></div><div>Brad Bassett</div></div>
