Installation Notes
This installation was completed in March of 2024. This customer came to me through a Grand Design RV Rally that I participated in as a vendor. We met at the rally and discussed a possible installation. The customer wanted to keep the installation relatively small and fit within a budget. We discussed various battery options and the customer ultimately decided to purchase Li Time lithium batteries on their own due to the relatively low cost of these batteries.
Based on our conversations at the rally, I put together a proposal to meet their relatively modest power needs. The plan was to add two 365 watt solar panels and a Victron MPPT solar controller. Install the customer provided new batteries inside the trailer and remove the original batteries from the trailer tongue. Add a Multiplus II inverter charger. And finally, add a battery monitor to track the batteries’ status. The customer agreed to the proposal and we set an installation date.
The system install went pretty smoothly. I was able to install all the equipment in the pass through storage at the front of the trailer. I added some plywood to the wall of the compartment to support the weight of the new equipment. The installation took two days to complete. Running cable from the roof down to the solar controller was a bit of a chore, but I was eventually able to get it fished through the roof and down through a bedroom cabinet into the pass through storage area. The Victron system components all communicate over an internal Bluetooth network to coordinate charging efforts.
Once all the components were installed, I tested their operation and spent time with the customers going over their functions. I also trained them on the Victron Connect app in order to interact with the new components.
