Expert Xantrex Freedom advice needed

Yes. Black is hot lead in. White is neural ac in and green is ground in. This is the AC-in's initial contact with the inverter. Nothing is between these wires and the spades on the boards. So whatever the missing two-lead component was, it is the very first thing ac goes through, as it bridges the two ac-in spades. Xantrex has nothing online that I could find that shows a schematic, and I couldn't find anyone else with one either. Hopefully someone has a two-line-in Freedom inverter sitting around that can identify the missing link. Thanks for your responses. Also if it helps, the scorch marks and the slight remains of the piece indicate it was round and maybe a half an inch across. That's all approximate. It does resemble a MOV from pictures I've seen, but I'm not knowledgeable on that level.
