First of all congratulations! I have the same trailer and a dog. You said basic solar flex but what does that mean? There are 4 different packages. I have the SF400 which only comes with a 2000 watt inverter. It doesn't have the second dedicated AC inverter. The FX600 comes with the soft start AC, second inverter and lithium batteries. This is one step from top of the line so not basic.

*Performance will vary based on available sunlight, battery size/type, and power usage.

Personally I wouldn't leave my dog unattended in the trailer for any extended period of time for too many reasons to list but I wouldn't have a problem with a short period. And I'd have a neighbor keep an eye out.



As far as the WiFi and security the unit comes with 4G LTE WIFI prep.
