This installation was completed in February of 2025.  The owner of this 5th wheel had two solar panels and a small Victron 75/15 MPPT Solar Controller installed by Nomad Neal while at Rolling Retreats in Elk City, Oklahoma having a Flex Armor roof installed.  He wanted additional solar panels eventually, along with other equipment, so he had Rolling Retreats add studs for four additional solar panels when the roof was sprayed.  Nomad Neal then referred the customer to me when he was ready for the additional equipment because the customer lived near me.  

When the customer contacted me, we discussed his needs and I put together an estimate with a system schematic for him to review.  The customer was happy with the proposed system and we set an installation appointment.

The installation took four days to complete.  I installed a Multiplus II 3kva 2×120 UL rated inverter charger to provide power to the RV.  There was an existing Magnum CSW1012 inverter in the RV dedicated to the residential refrigerator circuit.  I left this in place.  This allows the customer options for powering the refrigerator.   I replaced the existing 75/15 MPPT with a SmartSolar 150/100 MPPT solar charge controller and installed four additional 215 watt Hightec solar panels.  The customer supplied his own batteries for the installation.  He had two LiTime 12 volt 100 amp hour mini lithium batteries installed by Nomad Neal and also supplied a LiTime 12 volt 560 amp hour lithium battery he wanted added to the bank.  While it isn’t ideal to mix batteries of different sizes, the customer did not want to waste the two mini batteries he had recently had installed and I was will to make the proper accommodations to build the battery bank.  I was ultimately able to install the two mini batteries on top of the large 560 amp hour batteries with a mounting plate I built out of plywood.  It made the battery bank footprint quite small overall.  I finished off the system with a Cerbo-S GX and GX Touch 70 display.  The customer  had two Mopeka Pro Check LPG tank sensors, which I integrated into the Cerbo to monitor the on board propane tanks.  I also add three Ruuvi Bluetooth temperature sensors and integrated them into the Cerbo.

After the installation, I spent some time with the owner going over all the equipment and the Victron Connect App to interact with the equipment.  I also went over the VRM portal and how that monitored and controlled the system.  I sent him an invitation to join the VRM portal for his system so he could easily add it to his free VRM account.  We also set up a VRM widget on the owner’s phone to monitor the system.
