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.
Why Buy from Solar World Canada?
- Canadian solar-system experience and practical compatibility guidance.
- Calgary pickup by appointment and Canada-wide freight coordination.
- Support selecting compatible racking, inverters, monitoring and balance-of-system equipment.
- Project-focused recommendations instead of a one-size-fits-all product sale.
