VThe 12V Victron MultiPlus-II Inverter gives your mobile, marine, backup, or off-grid power system a dependable all-in-one solution for clean AC power and efficient battery charging. With 3,000VA of pure sine wave inverter output and a powerful integrated 120A battery charger, it is built to keep essential appliances, electronics, and system loads running smoothly.
Designed for real-world power conditions, the MultiPlus-II uses Victron’s PowerControl and PowerAssist technology to intelligently manage incoming AC power from shore power, generator, or grid input. It helps prevent overload while using battery power to support peak demand when needed, giving you more stable performance when your available power source is limited. UL 458 certified for RV and mobile applications, this inverter/charger is a strong choice for 12V battery systems, including LiFePO₄, AGM, and lead-acid batteries. Pair it with Victron GX devices for advanced monitoring and control, and build a smarter, more reliable power system for travel, marine use, backup power, or off-grid energy.
This inverter produces clean, stable pure sine wave power ideal for sensitive electronics like laptops, medical devices, communication systems, and appliances. You avoid buzzing, overheating, or performance issues commonly seen in modified sine wave systems.
The built-in high-speed charger delivers up to 120A of charging current, allowing fast battery replenishment for LiFePO₄, AGM, and lead-acid systems. This means less downtime and more usable power when you need it most.
PowerControl intelligently monitors incoming AC sources and automatically limits charging when necessary, preventing overload situations. This is especially useful when running from generators or limited shore power connections.
When sudden power surges occur, PowerAssist instantly supplements energy using your battery bank. This ensures stable output even when multiple appliances start simultaneously, preventing system shutdowns.
This inverter supports hybrid configurations including solar charge controllers, AC coupling, and generator inputs. It gives you the freedom to design a system that evolves with your energy needs.
Certified for RV and marine environments, this unit meets strict safety standards, making it a trusted choice for mobile power systems where reliability and compliance are critical.
When paired with Victron GX devices, users gain full visibility and control over their system. Monitor performance, adjust settings, and track energy flow remotely for complete peace of mind.
Victron provides a 5-year warranty policy, ensuring the absence of defects in materials, workmanship, and performance during the warranty period.
