I chose a 600W pure sine wave unit, which is plenty to power laptops etc. I did not want to install a larger unit (although there is room for it) because of the additional draw on the battery when the inverter is powered up regardless of the load on it. This Giandel unit got good reviews, hope it performs as promised. I chose this unit also because it has a remote on/off button, which is a feature most under-1000 watt units do not offer.
As with the rest of the equipment in the electrical compartment, the inverter will sit on a 1 1/2 inch platform to protect it from any possible liquid spill on the trailer floor plus a bit more air circulation underneath for cooling. Here you see the wood strips the inverter will sit on:
I had originally prewired for an inverter addition, so the only other new addition to the wiring was a circuit breaker from the battery positive bus to the inverter. I used a 42 amp breaker. The wire on both leads to the inverter is 2 gauge and as you can see very short runs to minimize voltage drop.
The negative side of the inverter 12V connection runs to the shunt bus so I can monitor the amp draw of the inverter on my Trimetric electical meter. All the connections were crimped and shrink wrapped as usual.
A the bottom of the photo you can see the extension cords from the inverter to the wall plug on the trailer dining area. These custom extensions were made using regular Romex 14/2 wire.
Here is the front area of the electrical compartment with the addition of the on/off inverter button and the remote electrical plugs:
