The Victron MultiPlus-II 48/3000/35-50 120V is the most popular 48V residential energy storage inverter/charger — the workhorse for off-grid homes, residential battery backup, and grid-tied solar + battery systems. 3000VA of pure sine inverter output (2400W continuous), 35A multi-stage battery charger, 50A AC transfer switch, ESS-capable for self-consumption mode.

Why 48V for residential

  • Lower battery current — same power as 12V at 1/4 the amperage; thinner cable, less voltage drop, longer cable runs
  • Standard for residential battery banks — most commercial lithium battery products (Pylontech, BYD, BattleBorn 48V, Discover, EG4, etc.) come in 48V
  • Pairs with high-voltage MPPTs — SmartSolar 150/35, 250/100, RS 450/200 all happy at 48V
  • Parallel scalability — add more MultiPlus-II units in parallel for 6kW, 9kW, 12kW systems
  • ESS mode for grid-tie — supports utility-connected self-consumption configurations

What 3000VA powers

  • RV / cabin air conditioner (mid-size unit, with PowerAssist for startup)
  • Microwave + coffee maker + refrigerator simultaneously
  • Single 120V power tool circuit (table saw, miter saw on intermittent duty)
  • Full home office + entertainment
  • Typical "essential loads" backup for a small home (lights, refrigerator, internet, electronics)
  • Off-grid cabin daily living load

Why the MultiPlus-II 48/3000/35-50

  • 3000VA / 2400W pure sine inverter — substantial AC capability per unit; parallel multiple for whole-home
  • 35A multi-stage charger — charges a 200Ah 48V bank in ~6 hours
  • 50A AC transfer switch — supports 50A grid or generator input
  • PowerControl + PowerAssist — boost limited shore/grid for peak loads
  • ESS-capable — self-consumption mode, peak shaving, time-shift
  • VE.Bus networking — parallel up to 6 units; or 3-phase (3 units)
  • Built-in current sensor — enables advanced ESS without external CT
  • Multi-stage adaptive charging — AGM, Gel, Flooded, LiFePO4, plus CAN-bus battery communication

Recommended applications

  • Residential off-grid — standalone home, 48V LiFePO4 bank, paired with SmartSolar 150/35 or 250/60
  • Residential backup power — essential loads backup for grid outages
  • Grid-tied solar + battery — self-consumption ESS mode for time-of-use rate optimization
  • Small commercial backup — retail, office, server room battery support
  • Telecom remote sites — 48V is the telecom industry standard
  • EV charging hybrid — buffer battery for Level 2 EV charger on a limited-amp service
