⚡ JAYCO MOTORHOME OFF-GRID UPGRADE ⚡
A practical power upgrade designed to improve battery capacity, solar recovery and 240V capability while retaining the existing Jayco and Projecta systems where suitable.
🔋 400Ah lithium battery bank
⚡ Victron MultiPlus-II 12/3000 inverter/charger
🚐 Victron Orion XS 50A DC-DC charger
☀️ 680W dual solar system
📊 Projecta Intelli-J monitoring
🌀 2 × Caframo Sirocco II fans
🔌 Additional 12V and USB outlets
The solar system is split across two independent arrays, with 440W feeding the Projecta system and 240W feeding a Victron SmartSolar MPPT 150/45.
With up to 50A charging while driving, approximately 44–47A realistic peak solar output and high-output shore charging through the MultiPlus, this setup gives the motorhome strong charging performance from multiple sources.
A clean, integrated system built for reliable off-grid touring and everyday comfort.
