Description
xVictron MultiPlus 48/5000/70-100 230V VE.Bus Inverter Charger
The Victron MultiPlus 48/5000/70-100 is a combined inverter and battery charger in a single unit, designed for off-grid, backup and hybrid power systems operating on a 48V battery bank. It delivers 5000VA of continuous inverter output at 230V AC and a 70A battery charger, making it a practical choice for residential off-grid installations, commercial backup systems and mobile or marine applications where reliable AC power is essential.
Key Features
- 5000VA continuous inverter output with a 230V AC sine wave output, suitable for demanding loads including motors and compressors.
- 70A multi-stage battery charger with adaptive charge algorithm, compatible with a wide range of 48V battery chemistries including lead-acid and lithium.
- PowerAssist technology supplements shore or generator power when load demand exceeds the available AC input, preventing overload trips.
- Two AC outputs: AC-Out 1 remains live during a mains failure (no-break switching), AC-Out 2 disconnects when running on battery to shed non-essential loads.
- VE.Bus communication port enables multi-unit parallel and three-phase configuration, as well as integration with Victron GX devices and the VEConfigure software.
- Transfer switch with a typical switchover time of less than 20 milliseconds, fast enough to keep most computers and sensitive equipment running without interruption.
- Built-in battery temperature and voltage sensing for accurate charge compensation.
- Programmable relay for generator start, alarm or load control functions.
Product Overview
The MultiPlus 48/5000/70-100 combines a full-featured inverter and a high-current charger in one chassis. The 48V nominal battery voltage is well suited to larger off-grid and backup systems where higher battery voltages reduce cable losses and allow more practical battery bank configurations. At 5000VA, the unit can handle substantial continuous loads while the 100A peak current capability allows it to start motors and other inductive loads without nuisance tripping.
The VE.Bus interface is central to the unit's flexibility. Up to six identical MultiPlus units can be connected in parallel to scale output capacity, or configured in split-phase or three-phase arrangements. This makes the MultiPlus a practical building block for larger systems without requiring a separate inverter management unit. When connected to a Victron Cerbo GX or other GX device, the system can be monitored and controlled remotely via the VRM portal.
PowerAssist is particularly useful in installations where the available generator or shore power supply is limited. The inverter draws from the battery to supplement the AC input, allowing a smaller generator to run loads that would otherwise exceed its rated output. The charger then replenishes the battery when load demand drops. This reduces generator running costs and wear in off-grid installations.

Applications
- Off-grid residential and smallholding systems with a 48V battery bank and solar or generator charging.
- Critical backup power for commercial premises, telecoms equipment and server rooms requiring fast transfer switching.
- Marine and large vehicle installations where 230V AC output from a 48V DC system is required.
- Scalable multi-unit parallel systems where output capacity needs to exceed a single inverter's rating.
- Three-phase off-grid systems when combined with additional MultiPlus units via VE.Bus.
- Generator support applications where PowerAssist reduces the required generator size and running hours.

Installation Notes
The MultiPlus 48/5000/70-100 operates at 48V DC and handles significant battery and AC currents. Installation must be carried out by a qualified electrician or MCS-accredited installer. All AC wiring must comply with BS 7671 (IET Wiring Regulations). For any grid-connected or grid-backup application, compliance with G98 or G99 engineering recommendations is required and notification to the relevant Distribution Network Operator (DNO) may be necessary. Configuration is performed via VEConfigure software over the VE.Bus interface. Correct battery cable sizing and fusing is critical given the high charge and discharge currents involved.
