Installation Notes

This installation was completed in March of 2026. The owners of this travel trailer live locally to me and stopped by my shop on the way home from a camping trip to discuss a possible solar system for their RV.  We had had a few telephone conversations prior to them stopping by, but I wanted to see the trailer in person to be able to give the best information for how to proceed to meet the needs of the customer.  When they stopped by, I was able to better gaugue how best to proceed with an installation.  The RV is a very long travel trailer (approximately 40 feet).  The customer had relatively modest power needs and wasn’t sure how long he would keep this RV so he didn’t want to put a large system in.  The RV had a factory mounted 370 watt solar panel and AGM batteries on the tongue in a storage box.  The customer had found a 628 amp hour Watt Cycle lithium battery and was interested in using that for the installation.  We had discussions about power needs and installation locations and at the end of our conversation, the customer asked if he could just leave the rig with me for the installation.  I agreed.  I put together a detailed estimate based on our conversations and sent it to the customer for final approval.  Once the customer agreed to the estimate, I ordered the parts (the customer had the battery he had found sent directly to me).  Once all the parts arrived, I began the installation.

The installation took two and a half days to complete.  I was able to install the battery and all the Victron equipment in the basement pass through storage compartment.  The customer lost some storage space in this compartment, but gained a good amount of storage in the large, multilevel, battery box on the trailer A-frame.  The installation was pretty straight forward because all the equipment was located in the same compartment.  I was able to utilize the factory solar wiring when I added the second solar panel to the system.  The hardest part of the installation was AC wire routing.  I had to run new wire from the shore cord to the Multiplus AC Input and then new wire from The Multiplus AC Output to the main breaker panel.  This required running wire in the covered belly of the trailer and took some time to find accessible paths for the wire run, but I was able to make it work.

Once the installation was complete, the customer returned to pick up the trailer.  I spent some time with the customer going over the installation.  I made sure the customer had the appropriate apps on his phone to interact with the equipment and spent time going over how to interact with each piece of equipment.
