The Finished Product !!

Here it is all done. The venting for the inverter works well. I only put one door back on the bottom and put it sideways. The piece it is hooked to is removable with 2 screws in case I need to get the batteries out. The little white panel is the on/off switch for the inverter. I left the bottom of the old converter hole open a little bit so if for some reason I need to vent the battery area all I need do is open the door. Air can flow in through the little grill on the bottom and out the door. The inverter has battery temp sensor so I am not worried about overheating the batteries. After talking to quite a few people in the know I have no concerns about the AGM batteries being vented inside. If not over charged they will not out gas is what I believe from talking to the pros. I also have a foam barrier separating the front half of the inverter from the back so the hot air can not be drawn back into the inverter causing a heat build up.
