Not sure if I am completely understanding your post. You say you had the 150a fuse blow on the Battery input? That would indicate that you wired it with the wrong polarity. If this is the case, and adjacent circuitry is fried, your unit is most likely toast. You can contact Eco-worthy and see if they have any repair service but I would doubt they do or that they would provide a replacement control board.

Perhaps an image of what damage you have might help.

100% correct , so the only part of the unit that is duff is a guess on my part the battery charging module as pictures , one end of the board is pv in the other is conected to the battery ,
