I currently work in low voltage electrical as my job so I understand a few things but would appreciate advice. I'm moving out to the country, just bought a 30ft trailer (not going to be moving it at all, it is staying put) there is no electrical grid hook ups there. I would like to power off of solar and wind ( I don't know if they can be combined on the same system) I work most of the day so I won't be home to use power until the evening, but mostly I'll run a tv, cellphone chargers, and a refrigerator. I feel confident enough in my abilities to do a diy build, but I don't know if that's better or more cost effective than a all in one system. Any pointers or tips would be helpful thanks!
