WT, voltage is not something I’ve thought a lot about....yet. But, battery backups have been in the back of my mind. My truck has a standard outlet that I can plug an extension cord into should I have a power outage. So, I guess it’s not too much of a concern.
What model gyres do you use and do they both run off one controller? That was probably the biggest selling point for me. 1 cord and no extra controller. I got enough cords under my tank. Not to mention Neptune’s reputation.
