Hi wrenches, I've got a architect client with a sub-optimal power situation on one of the projects he is working on. I'm running through a couple of scenarios that may work. Its a ADU (accessory dwelling unit) that is about 1100' from power. The farmer had taken it upon himself to bury some 4/0 a few years ago to run power out there. Voltage drop is the big issue and its not going to pass the AHJ inspection. We could just ditch the grid and go off-grid, but it seems like a shame to not tap into the grid resource. Instead of dealing with the voltage drop, I was thinking it may make sense to rectify that low AC voltage input and parallel a smallish battery bank (size is yet to be determined), then use an off-grid inverter to serve the loads at good voltage.
I am looking for feedback on this concept. What do you think? Also, are there any recommendations for good quality rectifiers with wide input voltage window? Thanks in advance for your help -- Mac Lewis *"Yo solo sé que no sé nada." -Sócrates*
