Hey! Bought an '09 Kandi Coco..72vac motor..but the magic smoke came out of the inverter/motor controller..no part number.. Greatland Electric Shenzhen original manufacturer.. doesn't seem too easy contacting them. Any thoughts on replacement/repair? I've done lots of Googling..tons of vfds & inverters but 72vdc to 72vac 3 phase inverter motor controller have not found. Thanks for any help you can give!
