I guess the secondary question is why would anyone use this system anyway in a grid interconnected environment. The only rationale I could see is to have some level of air conditioning when the sun is shining without having to go through the expense of adding a hybrid inverter and batteries. But by the time you install solar panels with a rapid shutdown system, the return on that investment seems terrible considering that much of the solar energy generated will be wasted unless you somehow need maximum cooling from this unit 365 days a year during the daylight hours.
