The Victron MultiPlus-II 24/3000/70-50 120V is the single-phase 120V version of the popular 24V/3000VA MultiPlus-II — 3000VA pure sine output (2400W continuous), 70A multi-stage charger, 50A AC transfer switch, single 120V AC output, UL 458 certified, ESS-capable. The right pick for 24V boats with 30A shore power, off-grid cabins, and single-phase 120V applications.

Single-phase 120V vs Split-phase 2x120V — which one?

Single-phase 120V (this model) Split-phase 2x120V
SKU PMP242305102 PMP242305132
AC output 1× 120V 2× 120V (split-phase 240V)
Shore power 30A shore connection 50A split-phase shore connection
240V household appliances No (needs external autotransformer) Yes (built-in)
Price $997.05 $1145.80

Choose Single-phase 120V if: your boat has 30A (not 50A) shore power, you don't have 240V household appliances, or you want the lower-cost option.

Choose Split-phase 2x120V if: you have 50A split-phase shore power, you have 240V appliances (well pump, dryer, water heater), or you're building a residential off-grid system.

What 3000VA powers

  • Marine air conditioner (mid-size unit, with PowerAssist)
  • Microwave + coffee maker simultaneously
  • Mid-size refrigerator + entertainment + lighting
  • 120V power tools (table saw, miter saw on intermittent)
  • Full home office + entertainment center
  • Whole-cabin "normal living" load on a yacht or off-grid setup

Recommended applications

  • Sailboat / trawler with 30A shore power — single-phase 120V is all you need
  • 24V off-grid cabin — single-phase 120V is plenty for most installs
  • 30A RV — single-phase 120V matches the shore connection
  • Backup power for small business — 24V battery bank, single-phase load
  • Mobile commercial — single-phase mobile setups
