The Ultimate Heavy-Duty Power Hub: Decoding 48/5000/70-95

Inverter, charger, and high-current transfer switch in one integrated platform.

The model name tells technical buyers exactly what they are getting: a native 48V battery platform, a 5,000VA inverter stage, up to 70A of DC charging, and a 95A AC transfer switch. This combination is intended for systems with heavy AC loads and substantial shore, grid, or generator input where a lower-current transfer stage could become the bottleneck.

Massive 5,000VA Pure Sine Wave Inverter

The inverter delivers 4,000W continuous at 25°C, 3,700W at 40°C, and 9,000W peak power. Clean 120V sine-wave output supports sensitive electronics and heavy household-style loads when the battery bank, wiring, protection, and ventilation are correctly engineered.

The 95A Transfer-Switch Advantage

A 95A transfer stage can pass a large 120V generator, shore, or grid source through the inverter/charger without imposing a 50A internal transfer limit. The installation still requires correctly sized upstream and downstream breakers, conductors, grounding, and code-compliant distribution.

70A Smart Battery Charger

When external AC is available, the MultiPlus-II becomes a high-output 48V battery charger. Charging voltage, current limits, and algorithms are configurable so the unit can be commissioned for the exact Epoch battery, managed BMS, and system design.

Advanced Victron Energy Management

PowerAssist, intelligent load separation, and fast backup transfer.

PowerAssist: Maximize Limited Shore or Generator Power

PowerControl first reduces battery charging to keep the configured AC source within its current limit. If the connected loads still need more power, PowerAssist supplements the AC source with energy from the battery, then uses spare source capacity to recharge when demand falls.

Dual AC Outputs for Smart Load Shedding

AC-Out-1 backs up critical loads and transfers to inverter power in less than 20ms. AC-Out-2 is reserved for loads that should run only while shore, generator, or grid power is present, helping keep water heaters and other non-critical loads from draining the battery bank.

Extreme Scalability: Parallel, Split Phase and Three Phase

Grow the power platform as system requirements expand.

240V split-phase architecture Two matching units can be configured in supported designs to provide 120/240V split-phase power through VE.Bus.

Up to six units in parallel Victron documents parallel operation for increased inverter and charging capacity, subject to system limits and professional configuration.

Three-phase capability Three matching units can form a supported three-phase system; larger arrangements require strict Victron design and commissioning rules.

Frequently asked questions

Victron MultiPlus-II 48/5000/70-95 FAQs

Common questions about transfer current, split phase, lithium charging, wiring, monitoring, and model selection.

What do the numbers 48/5000/70-95 mean?

Victron’s model name summarizes the core ratings:

48: designed for a nominal 48V battery system.
5000: 5,000VA inverter rating, with 4,000W continuous output at 25°C.
70: up to 70A DC battery charging.
95: 95A AC transfer-switch and maximum AC-input rating.

Why would I choose the 95A transfer-switch version?

The 95A transfer switch allows the unit to pass a substantially larger 120V shore-power, generator, or grid source than a 50A model. It is suited to heavy-duty systems where the upstream source and downstream distribution are designed for that current. Proper breakers, conductors, grounding, and local-code compliance are still required.

Does one MultiPlus-II provide 120V or 240V output?

One unit provides 120V AC. Victron documents supported split-phase designs using two identical units configured through VE.Bus to create a 120/240V system. Parallel or split-phase systems must use matching models and firmware and should be commissioned by a qualified installer using Victron’s current configuration guidance.

What DC fuse and battery cable size does Victron recommend?

Victron’s current 120V manual lists a 200A DC fuse for the 48/5000/70 model, AWG 2/0 positive and negative cables for runs from 0–5m, and AWG 4/0 for runs from 5–10m. The table assumes the specified battery capacity range and installation conditions; local code, ambient temperature, cable construction, routing, and actual run length may require different sizing.

What is the difference between AC-Out-1 and AC-Out-2?

AC-Out-1 is the inverter-backed no-break output. If the AC source fails, the inverter takes over in less than 20ms for supported loads. AC-Out-2 is intended for loads that should operate only while shore, generator, or grid input is present; it disconnects on battery operation and reconnects after the AC source has stabilized.

Can I monitor and control this inverter from my phone?

Yes, with additional Victron communication hardware. A Cerbo GX or Ekrano GX enables local system integration and VRM remote monitoring. A VE.Bus Smart Dongle supports local Bluetooth monitoring and selected controls. An MK3-USB interface and a separate RJ45 UTP cable are used for computer-based configuration and firmware work.

Can the 70A charger be configured for Epoch LiFePO4 batteries?

Yes. The charging profile must be configured for the exact battery or managed-BMS system rather than left on an unsuitable factory profile. Use VictronConnect or VEConfigure through the supported interface, and follow Epoch’s current charge-voltage, current-limit, temperature, and BMS-communication guidance for the selected battery bank.

How many MultiPlus-II units can be connected together?

Victron documents up to six Multi units operating in parallel for higher output. Two identical units can be configured for supported 240V split-phase systems, and three can form three-phase systems. Larger systems require matching hardware, compatible firmware, correct VE.Bus configuration, suitable batteries, and professional AC/DC protection design.

Can this inverter be installed outdoors or in a wet compartment?

No. The current Victron datasheet lists the enclosure as IP22, and the installation manual requires a dry, ventilated location. Do not install the unit in wet, dusty, explosive, or poorly ventilated spaces, and maintain the manufacturer’s required clearance around the enclosure.

Is PMP482505300 the UL 1741-listed version?

Do not assume so from the family name alone. Victron’s current catalog identifies PMP482505300 as the 120V 50/60Hz variant and separately lists PMP482505120 as the UL 1741 version. Confirm the exact product label, listing, and local authority requirements before purchasing for a permitted grid-interactive installation.
