What Is Included?

One Victron MultiPlus-II inverter/charger. Battery cables, DC protection, AC breakers, GX monitoring equipment, solar charge controllers and installation hardware are sold separately unless specifically stated.

Recommended System Components

  • Victron Cerbo GX and GX Touch for monitoring.
  • Victron SmartShunt or BMV battery monitor.
  • Victron SmartSolar MPPT charge controller.
  • Victron Lynx Distributor or correctly engineered DC bus and protection.
  • High-current 12V battery bank, properly sized conductors, disconnects and fuses.

Important 12V Design Note

A 2400W AC load can require well over 200A from a 12V battery bank after inverter losses. Battery capability, conductor size, fuse protection and voltage-drop calculations are critical. For longer cable runs or frequent high-power use, a 24V or 48V architecture may be more practical.

Frequently Asked Questions

Does it include an MPPT solar controller?
No. Add a compatible Victron SmartSolar MPPT sized for the array and battery bank.

Can it work with a generator?
Yes. PowerControl and PowerAssist can manage limited generator or shore-power capacity when properly configured.

Is it suitable for lithium batteries?
It can be configured for many lithium systems, but battery-BMS compatibility and charging settings must be confirmed.
