Stand-alone system with DC
Yesterday, I had a conversation with a nice gentleman who has decided to get into the international PV business. He is planning a project in the United Arab Emirates. This project involves a stand-alone system of 10kW DC without an inverter with UPS battery backup for 24 hours or more. All loads will be also DC(lighting, refrigerator, etc). Now, I am not the most knowledgeable person in the PV field, but wouldn't the project require one heck of a lot of batteries? And what about no inverter being involved???` Is this project even feasible? Would appreciate any input/insight.
