The Victron MultiPlus-II 48/5000/70-95 is a 48V inverter/charger built for residential solar, off-grid, and backup power systems. It's designed for installers and DIY solar owners who need a reliable single unit that inverts, charges, and manages transfer between grid and battery power. This is a 48V inverter/charger with a split-phase output configuration and an integrated pure copper transformer producing a low-frequency pure sine waveform. The manufacturer data provided does not specify architecture classification (off-grid only vs. hybrid grid-tie) or UL/IEEE listings for this unit — treat those as unconfirmed until verified against the manufacturer documentation. Note: If you would like to review the manufacturer Product Specifications, Warranty, Brochure, etc., for this system, please refer to the "Resources (System Manuals and Warranty)" Tab above on this page.

Critical Power & Interconnection Requirements

  • AC Output Voltage: 120V, split-phase capable output
  • DC Battery Voltage: 48V systems only
  • Configurable grid or solar input priority (source-selectable per manufacturer data)
  • CAN/RS485 protocols supported for BMS communications
  • NOT rated for 12V or 24V battery banks
  • Continuous and surge AC output figures in Watts are [NEEDS VERIFICATION] — not provided in source data beyond model nomenclature (5000)
  • Grid sell-back capability [NEEDS VERIFICATION] — not stated in manufacturer data
Pro-Installer Tip: On split-phase inverter/charger installs, a common friction point is neutral-ground bonding: get it wrong and you'll trip GFCI/AFCI protection or fail your inspection outright. Verify bonding is set correctly for your application (mobile vs. stationary/residential) before energizing the system — this prevents nuisance fault trips and protects downstream BMS communication over CAN/RS485 from ground-loop noise. Confirm your bonding point and neutral continuity with a Digital Multimeter before closing up the enclosure. This is a direct NEC Article 690/706 compliance point your utility inspector will check first.
