The Victron MultiPlus-II 24/3000/70-50 2x120V is the split-phase 24V inverter/charger — 3000VA pure sine output (2400W continuous), 70A multi-stage charger, 50A AC transfer switch, split-phase 120V/240V output, UL 458 certified, ESS-capable for grid-tied applications. The right pick for 24V boats, off-grid homes, and RVs needing 50A split-phase shore power.

Why 24V split-phase?

  • Split-phase 2x120V output — supports US 50A shore power and household 240V appliances
  • 24V house bank advantage — same power at half the current; thinner cable, less voltage drop
  • Marine standard — many sailboats and larger powerboats use 24V house banks
  • ESS-capable — supports grid-tied energy storage system mode for self-consumption

What 3000VA powers

  • RV air conditioner (one mid-size unit with PowerAssist)
  • Microwave + coffee maker + other AC loads simultaneously
  • Mid-size refrigerator + entertainment system + lighting
  • 240V household appliances (well pump, water heater, dryer on intermittent)
  • Full home office or full RV "normal living" load
  • Off-grid cabin essentials including pump, refrigeration, and small kitchen run

Why the MultiPlus-II 24/3000/70-50 2x120V

  • 3000VA / 2400W pure sine inverter — substantial real-AC capability
  • Split-phase 120V/240V — 50A shore power emulation, household 240V equipment
  • 70A multi-stage charger — charges a 400Ah 24V bank in ~7 hours from shore
  • 50A AC transfer switch — automatic shore/generator transfer
  • PowerControl + PowerAssist — boost limited shore power for peak loads
  • ESS-capable — supports grid-tied energy storage system mode
  • UL 458 certified — legal for mobile and marine use
  • VE.Bus networking — parallel or 3-phase capable
  • Built-in current sensor — enables advanced ESS features without external CT
  • Multi-stage adaptive charging — AGM, Gel, Flooded, LiFePO4 profiles
