The Westy is equipped with a second battery used to power accessories appliances and other items inside the bus. in preparation for the maiden camping voyage, I got it installed and wired up to the 500 W inverter that I have had for sometime. I chose to install the inverter in the spare tire well/closet area so that if I upgraded inverters at some point in time, this is where it would likely be mounted. This was also an opportunity to test the Renogy solar charger system, and so I connected them both and powered the Ausranvik cooler for a day. I am happy to report that all worked well, although the inverter is pretty noisy inside the confines of the bus. At some future point, I will re-wire the main house light to connect to the house battery rather than the starting battery.
