Victron MultiPlus-II 48/5000 – 48V 5000VA Inverter/Charger - PMP482505012

The Victron MultiPlus-II 48/5000 (PMP482505012) is a professional-grade 48V 5000VA inverter and adaptive 70A battery charger combined in a single compact enclosure. Engineered for home energy storage systems (ESS), off-grid power, marine, and mobile setups, it features dual AC outputs, an ultra-fast sub-20ms transfer switch, and smart power management to prevent overload from shore power or backup generators.

Robust 5000VA Power Output: Delivers up to 4000W of continuous pure sine wave power (with a 9000W peak surge) to start and run high-demand household appliances. Sub-20ms Automatic UPS Transfer: Switches seamlessly from grid or generator power to battery inverter power in milliseconds to keep sensitive electronics online. Smart Adaptive 70A Battery Charger: Features intelligent multi-stage charging designed to maximize battery health, efficiency, and overall lifespan for 48V battery banks. PowerAssist Peak Boosting: Automatically boosts limited generator or shore power supply using energy from your battery bank to manage peak loads without overload. Dual AC Outputs: Separates essential backup loads from heavy non-essential appliances, ensuring critical devices remain powered during outages. Compatible with lithium, AGM, gel, and flooded batteries.

Victron MultiPlus-II 48/5000/70-50 230V – PMP482505012

Take complete control of your energy with the Victron MultiPlus-II 48/5000 Inverter/Charger. Designed to serve as the heart of modern off-grid, marine, RV, and Energy Storage Systems (ESS), this powerful unit seamlessly blends the capabilities of a pure sine wave inverter, an advanced 70A battery charger, and a high-speed transfer switch into one sleek, efficient housing.
Uninterrupted Power Backup (UPS Function)
Never worry about sudden grid blackouts or shore power interruptions. The MultiPlus-II features an integrated transfer switch that takes over instantly in less than 20 milliseconds when power fails. That means sensitive electronics, home appliances, computers, and medical equipment continue running smoothly without a single flicker.

Smart PowerControl & PowerAssist Technology
Prevent blown fuses and tripped generator breakers with Victron's intelligent energy management features. PowerControl automatically caps battery charging to prevent overloading limited AC sources like small generators or shore connections. When demand spikes further, PowerAssist steps in to supplement the AC supply with power drawn directly from your battery bank.
Dual AC Outputs & ESS Ready
The MultiPlus-II is equipped with two separate AC outputs. The main output delivers uninterrupted backup power, while the secondary output operates only when AC grid or generator power is available - ideal for non-essential heavy loads like water heaters or air conditioners. Fully optimized for Energy Storage Systems (ESS), it works dynamically with solar arrays and battery banks to minimize grid consumption and lower utility costs.
