I used this unit with 100W solar panel, charge controller and 12 volt battery to run 24x7 in 90 degree temps.of course the unit drew from the battery at night, but the solar capacity allowed for full recharge before next evening. I think this is a persistent solution for people wanting to do similar.Maximum observed power consumption was 3amps. Hopefully this will let you pick the correct battery or power station. Duty cycle will depend on temp differential, especially since the unit is not as insulated as you'd like. Condensation will form on the outside of the unit due to thermal transfer.
