Entegra Accolade XT Gets Full Victron RV Solar Upgrade | 1200W + 628Ah Off-Grid Build

Welcome back to Tucson RV Solar! This time we’re down in Yuma, Arizona working on a beautiful Entegra Accolade XT Super C motorhome and giving it the full Victron off-grid treatment. This RV came in with only 200 watts of factory solar, a Xantrex inverter setup, and limited off-grid capability. By the time we’re done, this coach is transformed into a serious off-grid machine capable of running air conditioners, charging from the alternator properly, and supporting future battery expansion. For this build we: ✔ Installed 1,200 watts of rooftop solar ✔ Added 600Ah of lithium battery storage ✔ Installed a Victron Multiplus II inverter/charger ✔ Added Victron SmartSolar charge control ✔ Installed Cerbo GX + Touch 70 monitoring ✔ Reworked the Firefly transfer switch system ✔ Installed dual soft starts for off-grid A/C operation ✔ Added DC-to-DC charging for proper alternator charging ✔ Removed factory Xantrex equipment ✔ Built a fully custom inverter and distribution board One of the biggest challenges on this build was working around the Firefly multiplex system and redesigning the transfer switch setup so the customer can run their air conditioners while off grid. We also removed the factory Starlink setup to maximize roof space and squeezed six 200 watt panels onto the roof using a hinged mounting setup for future serviceability. This Entegra Accolade XT now has: 🔋 Victron-powered off-grid capability ☀️ 1,200 watts of solar charging ⚡ 600Ah lithium battery bank ❄️ Off-grid air conditioner operation 📱 Full Victron VRM remote monitoring 🔧 Room for future battery expansion If you enjoy detailed RV solar installs, Victron upgrades, lithium conversions, and real-world off-grid RV builds, make sure to subscribe and follow along with future projects from Tucson RV Solar. #RVSolar #VictronEnergy #IntegraAccolade #OffGridRV #LithiumBattery #RVLife #SolarPower #MotorhomeUpgrade #SuperCRV #VictronMultiplus #RVUpgrades #TucsonRVSolar #RVLiving #Boondocking #RVTech
