Victron Energy PMP482505010 MultiPlus-II 48/5000/70-50 Inverter Battery Charger
Victron Energy MultiPlus-II 48/5000/70-50 Inverter Charger
5000VA, 96% efficient, 9000W peak the high-power 48V MultiPlus-II for large off-grid and commercial installations
Product Overview
The Victron Energy MultiPlus-II 48/5000/70-50 (PMP482505010) is a high-power 48V inverter and battery charger built for large off-grid solar systems, commercial backup installations, and serious marine and mobile power setups that demand sustained high output and fast battery recovery. Delivering 4000W continuous inverter output at 25°C (3700W at 40°C), a 70A battery charger, and a 9000W peak power rating at 96% maximum efficiency, it is one of the most capable single-unit inverter chargers in the Victron range.
As part of the MultiPlus-II series, it brings the full suite of next-generation Victron capabilities: AC feed-in support up to 4000VA for grid-interactive solar configurations, integrated battery voltage and temperature sensing, and complete remote monitoring and control via the free Victron VRM portal from anywhere in the world. The 48V platform at 5000VA suits whole-of-home off-grid systems, large commercial backup installations, and any build where sustained high power output, high-efficiency operation, and deep system integration are non-negotiable. Like all MultiPlus models, it transfers to battery-backed inverter output in under 20 milliseconds delivering true UPS performance for any connected load.
Important: This product must be installed by a licensed electrician. It involves mains AC voltages and connection to shore power, generator, or grid supply.

Features & Benefits
- 5000VA / 4000W continuous 9000W peak: At 4000W continuous (3700W at 40°C) and 9000W peak, the MultiPlus-II 48/5000/70-50 runs whole-of-home loads, commercial equipment, and multiple high-draw appliances simultaneously. Air conditioners, induction cooktops, water pumps, workshop tools, and large inverter loads are all within reach and the 9000W peak handles the heaviest motor and compressor start-up inrush without flinching.
- 96% maximum efficiency: The highest efficiency rating in the MultiPlus-II 48V range covered in this batch. At 96%, energy losses through the inverter stage are minimal translating to less heat generated, lower parasitic draw on the battery bank, and more usable energy delivered to loads from every cycle. Over a full season of daily cycling, that efficiency advantage compounds meaningfully.
- 70A battery charger large bank recovery: At 70A into a 48V bank, this unit can restore a 500Ah battery bank depleted to 50% in under four hours under optimal conditions. For installations cycling large battery banks daily whole-of-home off-grid, commercial backup, and large marine systems fast recharge from generator or shore power directly reduces runtime costs and maximises solar absorption windows.
- AC feed-in support up to 4000VA: The largest feed-in capacity in this MultiPlus-II batch, enabling high-power grid-interactive self-consumption and grid-export configurations when combined with compatible grid-tie inverters and Victron GX devices. Suitable for large-scale solar installations moving beyond off-grid operation into genuine grid interaction.
- True UPS under 20ms transfer: When grid, shore, or generator power is lost, the MultiPlus-II transfers to battery-backed inverter output in under 20 milliseconds. At 5000VA output, entire home or commercial loads continue without interruption no restarts, no data loss, no disruption to sensitive equipment.
- PowerAssist peak power from the battery: When loads momentarily exceed shore or generator capacity, the MultiPlus-II draws from the battery to bridge the gap instantly. Once demand drops, charging resumes. At this power level, PowerAssist means a mid-sized generator can back up loads that would otherwise require a much larger, heavier, and more expensive unit.
- PowerControl intelligent high-power input management: Set a maximum AC input current and the MultiPlus-II dynamically manages charging around all running loads preventing generator or shore supply overload automatically and continuously, regardless of load variation throughout the day.
- Battery voltage and temperature sensor included: Integrated sensing adjusts charge voltage in real time for ambient temperature, protecting large 48V battery banks from overcharge in Australian summer heat and undercharge in cold conditions without manual adjustment and without an additional accessory.
- Full VRM remote monitoring and control: With a compatible Cerbo GX or Color Control GX, the MultiPlus-II connects to Victron's free VRM portal for complete remote access monitoring, control, and configuration from any device, anywhere in the world. For large or remote installations, the ability to diagnose, adjust, and manage the system without a site visit is a significant operational advantage.
- Parallel operation up to 6 units: Where output beyond 5000VA is required, up to 6 MultiPlus-II units can be paralleled. Three-phase and split-phase configurations are supported where applicable check the Victron datasheet for model-specific capabilities.
- Search mode standby 2W: Despite its high output rating, Search mode standby draw is just 2W keeping overnight and light-load battery drain minimal in large off-grid and backup installations.

Frequently Asked Questions
How does the MultiPlus-II 48/5000/70-50 differ from the 48/3000/35-32?
The 48/5000/70-50 delivers significantly higher continuous output (4000W vs 2400W at 25°C), a higher peak power rating (9000W vs 5500W), a larger battery charger (70A vs 35A), higher maximum efficiency (96% vs 95%), and double the AC feed-in capacity (4000VA vs 2500VA). It is designed for whole-of-home off-grid, large commercial, and high-demand installations where the 3000VA model would be undersized.
What size battery bank is recommended for a 5000VA off-grid installation?
Battery bank sizing depends on daily energy consumption, desired autonomy, depth of discharge, and battery chemistry. As a general guide, a whole-of-home 48V off-grid system at this output level typically requires a minimum of 400–600Ah at 48V but a full load assessment by a licensed off-grid system designer is strongly recommended before specifying battery capacity.
Can this unit support a whole-of-home off-grid solar system?
Yes. At 4000W continuous and 9000W peak, the MultiPlus-II 48/5000/70-50 is sized for whole-of-home off-grid operation, including air conditioning, cooking, and high-draw appliances. System design battery bank, solar array, and charge controller sizing should be completed by a qualified off-grid installer.
Can I monitor and manage this installation remotely without visiting the site?
Yes. With a compatible Victron Cerbo GX or Color Control GX, the MultiPlus-II connects to the free VRM portal for full remote monitoring, control, and configuration from any device, anywhere in the world including real-time system data, alerts, and parameter adjustments without a site visit.
Does this product require a licensed electrician for installation?
Yes. The MultiPlus-II 48/5000/70-50 connects to mains AC voltages shore power, generator, or grid supply and must be installed by a licensed electrician in accordance with Australian electrical standards. Do not attempt self-installation.
