Currently I am traveling with my RV and I have some solar panels on top that charge the 12 volt RV batteries. Occasionally I plug into a RV campground but rarely, I also run my generator for an hour every other day. I’d like to find a stable way to run my Vera. I’m wondering if when I get an adapter that fits the Vera plug which is 12 volts, can I run it off my 12v RV battery? However the RV battery would be 12.1v to 13.6v during charging and 14v during bulk charge. If it’s not possible is there a device that can limit the voltage to just 12 volts from a RV batteries? I saw the backup battery options for about $25 but those only last 8 hours and are charged via 120v instead of 12v. We run a tplink micro travel router off of a RV power USB port and it is always running along with a phone that is always in hotspot mode and in the window, so that I have continuous Wi-Fi. The only thing I have to figure out is how to keep the Vera running 24/7 without 120v.
Laptop backup batteries are 19v
This scenario would be great to run a security system off grid, while at a camp ground and out on a hike, etc, and get cell notifications.
