  1. LOL, no I bought the 3 inverters with the 74-10 firmware, the replacement one is a older model. It is just that I feel it is not good to downgrade the 74 10's to an older firmware of witch I am not certain that it will work. My supplier is not very willing to help. But I will contact them again. Thanks for the info
