Trying to mount my electronics in the same Bay with the batteries was going to be a real pain in the ass. To do it right I needed to separate the AGM starting battery from all the electronics. Elected to mount all of the electronics under the bed in the storage area. I will cut a rectangular opening in each side and put a regular AC register vent to let some air flow through that area. From what I gather as long as I'm not running AC units with this inverter it will build some heat but not get crazy hot. Going with the multiplus II 12 volt 3000 VA inverter. For the price point without going absolutely nuts everything I gather Victron has really good products. Controller will be a victron MPPT 150/45. Selecting the correct controller is extremely important to make the system as efficient as possible. My battery guy who is a tech wizard helped select the controller. He said victron controllers don't scale correctly and rattled off enough numbers to make my head spin. You look online and think you are able to figure out how to select the right one and then I just threw all that out the window and gave up. Then also mounted in that area will be Victron Serbo that lets all the components talk to each other. The brain of the system so to speak. The batteries I bought also talk to the Victron components through cables. Components are just sitting there for the photo it will need to be mounted up higher to get air around them. This location keeps them away from the sand during a big storm at glamis as well. This inverter does add 40 lb but I still figure with the whole system I'm going to be 180 lb lighter
