OK guys I am always in the learnng mode and looking for new opputunities. For the last 7 years I have done a lot of of off-grid Solar PV designs for the telecom sector.
Most of these applications are outdoor cabinets that do not require any cooling other than fans. So everything is straight 24 VDC with an inverter to power tower and ground lighting.
Well now I see an opputunity to design off-grid solar for consumers like cabin owners who need a refrigerator and maybe a window shaker AC unit.
I am thinking that a DC unit maybe more effecient by eliminating the inverter, especially an expensive True Sine Wave inverter usually reuired to run motor loads.
So my question is generic, am I smoking crack? Are there good effecient DC powered refers and window shakers out there, and how do they compare to their AC cousins assuming single phase operation?
What is throwing me is my inside the box thinking, especially with Electric Vehicles. EV's use a battery and convert to 3-phase AC for effeciency, rather than a DC motor. But window shakers and refers are single phase?
