About this item
Power your system with the Victron MultiPlus-II 24/3000/70-50 (UL 458), a high-performance 24V inverter/charger designed for off-grid, mobile, and hybrid energy systems. Delivering 3,000 VA of pure sine wave inverter power and a 70A battery charger, it provides reliable, clean AC power for demanding applications.
Equipped with PowerControl and PowerAssist technology, the MultiPlus-II intelligently manages available power from generator, shore, or grid sources, preventing overload by supplementing peak demands with battery power when needed – and automatically recharging when demand drops. An external current sensor extends input management up to 100A, enabling greater flexibility in power-limited environments.
Built to meet UL 458 certification standards, this unit ensures safe, efficient, and reliable performance in both mobile and stationary applications – delivering intelligent power management and uninterrupted energy wherever you need it.

Frequently Asked Questions
Does the MultiPlus-II 24V work with the Husky 2?
Yes. The 24V MultiPlus-II is listed as compatible with the 24V HUSKY2 INV battery system, and the Husky 2 INV supports closed-loop communication. That means the inverter reads true state of charge from the battery's BMS instead of estimating from voltage.
What does PowerAssist do?
PowerAssist lets the inverter supplement a limited AC supply with battery power. On a 15A shore or generator connection, brief overloads are covered from the battery rather than tripping the breaker. PowerControl works alongside it, limiting how much of the incoming supply is used for charging.
Do I need an external current sensor for 100A input?
Only if you want input management above the standard range. The MultiPlus-II handles shore and generator input natively, and adding an external current sensor extends input management up to 100A, which is useful in power-limited installations where you are managing a large incoming supply.
Is the MultiPlus-II UL 458 certified?
Yes. UL 458 is the safety standard covering inverters in RV and mobile applications, which matters for insurance, RV park compliance and professional installation sign-off. The unit is rated for both mobile and stationary use.
What does the 70A charger mean in practice?
The 24/3000/70-50 delivers 3,000VA of inverter output with a built-in 70A battery charger. At 70A, a 200Ah 24V battery recharges from empty in roughly three hours on shore power or generator, allowing for the taper as it approaches full.
Is the Victron MultiPlus-II 24V 120V Inverter/Charger worth considering for Black Friday 24V off-grid power systems?
It combines 24V battery-side inverter and charger functions in one unit. During Black Friday or Cyber Monday, compare its current listed price with other products that meet the same requirements. Check the final checkout total and any published offer terms before treating it as a sale.
What affects the total cost of installing the Victron MultiPlus-II 24V 120V Inverter/Charger?
Confirm battery charging profile, AC loads and system wiring. Compare power rating and combined hardware cost versus alternatives, and review the product specifications and warranty before ordering. A seasonal price reduction is only useful if the product fits the intended system.
