I believe you need to fuse or provide a circuit breaker to the 120V AC circuit providing power to the inverter, as well as circuit protection to the circuits that are fed 120 V power from the inverter.

I am not aware of circuit protection from the inverter to the battery side of the inverter and that may be fused or have a breaker in the inverter. Perhaps someone more knowledgible on that side of the inverter can respond. However I do have circuit breakers for the battery output to handle the total battery loads, plus every individual DC circuit also has fuse or circuit breaker protection.

Fuses or breakers need to be as close to the power source as possible.

thanks. also where are you all puting your inverters. i was going to put all my stuff where my a/c condensor and fan where since that is well vented

thanks petar

On the installation instructions for inverters that I have seen a distance of 10 feet or less from the batteries is where the inverters are going to go. On my last bus they were under the bed and the batteries were in a compartment behind the tag axle. On my current bus they are in the second bay and the batteries are in the center of the bus in line with the fuel tank directly behind the second bay.

Both installations were a compromise. In the first I had to disassemble a lot of the bed just to access the inverters and cooling required an auxiliary fan with associated ducting. But the batteries were accessible.

In the second the inverters are readily accessible, but to get at the batteries the entertainment center has to come out. There is no way to get at the batteries without doing that.

No matter what choice anyone makes on the location of any of the components or systems it is going to be a compromise between preserving space, accessibility, and ease of service. To confuse your decision even more weight distribution has to be considered. I have about 700 pounds of house batteries. Not only does weight distribution side to side become a factor, but you have to consider axle weights fore and aft also. My batteries might be more accessible if moved forward with a panel at the center rear of the first bay, but moving them the three feet or so forward might push my front axle weight over the limits unless I limited storage in the first bay to feather pillows.

Petar,

Keep the inverter as close to the batteries as Jon pointed out. You should also have a fan in the compartment that vents to the outside. Mine is set to come on at 100 degree’s. The inverter has it’s own cooling fan internal, but they generate a lot of heat and need cooling circulation.
