Tiffin Allegro Red 37PA
Basic Parts List
This installation was completed in October of 2022. The owner of this rig was referred to me by Battle Born Batteries.
The owner and I discussed what he was looking for and how he wanted to use his motorhome. The motorhome had an existing Magnum 3012 pure sine wave inverter with an ME-RC remote display. It also had three solar panels (of unknown make) connected to a Jaboni solar controller. Based on our discussions, I put together a proposal for a solar and battery upgrade. The owner accepted the proposal and we set an installation date. The owner lived in southern California and he was willing to come to northern California to my location for the installation after our discussions.
The installation was pretty straight forward. I had completed an almost identical installation on a different motorhome a couple of weeks prior. I removed the four existing volt lead acid batteries and replaced them with six Battle Born GC2 100 amp hour lithium batteries. The motor home had an OEM sliding battery tray and the Battle Born GC2 batteries fit perfectly. I also added a Victron SmartShunt in the battery bay to monitor the battery bank. I then removed the OEM solar controller and replaced it with a Victron 150/100 MPPT. The OEM solar controller was in the bay next to the batteries. This bay was also where the Magnum inverter was located. I added a Midnite Solar Babybox DIN rail breaker box with MNEPV DIN rail breakers to protect the battery and solar connections to the MPPT. I utilized the existing 10 AWG solar wiring installed by the manufacturer to connect the solar panels to the solar controller. I removed the existing solar panels and replaced them with eight Newpowa 200 watt solar panels. The solar panels were installed in a 4S2P configuration to get the voltage up and keep the amperage low enough to properly utilize the existing solar wire. Once the installation was completed, I spent some time with the customer going over everything. He and his wife were looking forward to leaving my place and heading to a boondocking spot for the weekend to put the new system to the test.
