Victron Energy MultiPlus 48/5000/70-100 is a combined inverter and charger designed for off-grid, grid-tied, marine, RV, and backup power applications.
Below is a detailed overview of its key features, based on available information:
Key Features of the Victron MultiPlus 48/5000/70-100 (48V, 5000 VA)
Combined Inverter and Charger:Inverter: Converts 48V DC to 230V AC (or 120V AC for specific models) with a pure sine wave output, ensuring compatibility with sensitive electronics.
Continuous Output Power: 5000 VA (4000W at 25°C, 3700W at 40°C, 3000W at 65°C). Peak Power: 10,000W, capable of handling high inrush currents for starting heavy loads like motors or air conditioners.
Charger: 70A DC battery charger for efficient charging of 48V battery banks, compatible with lead-acid, lithium-ion, and other battery types.
Single AC Input with High-Speed Transfer Switch:Connects to one AC source (e.g., grid or generator) and switches to inverter power in less than 20 milliseconds during grid failure, ensuring uninterrupted power for critical loads.
Transfer Switch: 100A, supporting robust integration with high-power AC sources.
Two AC Outputs:Main Output: No-break functionality, seamlessly supplying power to connected loads during grid or generator failure.
Second Output: Active only when AC input is available, ideal for non-critical loads (e.g., water heaters or air conditioners) to prevent battery drain.
PowerAssist Technology:Prevents overload of limited AC sources (e.g., generator or shore power) by:Reducing battery charging when an overload is detected. Boosting AC output with battery power to supplement the source during high demand.
PowerControl:Manages limited AC input current by setting a maximum limit (via Multi Control Panel or software). The MultiPlus prioritizes other AC loads and uses spare capacity for battery charging, preventing overloads.
Parallel and Three-Phase Operation:Up to 6 units can be paralleled for increased power output (e.g., six 48/5000 units provide up to 25kW/30kVA output and 420A charging capacity). Configurable for three-phase or split-phase operation (e.g., 230V/400V WYE or 120/240V), ideal for larger systems.
Remote Monitoring and Control:When paired with a GX device (e.g., Cerbo GX or Venus GX), enables local (LAN) or remote monitoring/control via the Victron VRM app or portal on phones, tablets, or PCs. Supports advanced features like auto-starting a backup generator.
Adaptive Charging:Optimizes battery charging with a 4-stage adaptive process (bulk, absorption, float, storage) tailored to battery type and condition.
Charge voltages:Absorption: 57.6V DC Float: 55.2V DC Storage: 52.8V DC Supports lead-acid, lithium-ion (LiFePO4), and other battery chemistries.
High Efficiency and Low Standby Power:Maximum efficiency: 94–96%. Zero-load power: 18W (standard), 12W in AES mode, reduced further in Search mode. Search mode reduces power consumption by ~70% during no-load operation by turning off the inverter and checking for load every two seconds.
Versatile Applications:Suitable for off-grid, grid-connected PV systems, marine, RVs, industrial, and telecom applications. Compatible with MPPT solar charge controllers and grid-tie inverters for Energy Storage Systems (ESS).
Configuration Flexibility:Basic settings adjustable via DIP switches. Advanced configuration through VEConfigure software, VictronConnect, or VE.Bus to USB MK3-USB interface (sold separately). Programmable relay for alarms or custom functions (e.g., generator start/stop).
Certifications and Warranty:Certified to EN/IEC 62109-1, IEC 60335-2-29, and UL 1741/CSA C22.2 (for 120V models). 5-year standard warranty, extendable to 10 years in some regions.
Physical and Electrical Specifications:Input Voltage Range (DC): 38–66V. AC Input: 187–265V AC, 45–65 Hz (230V models) or 120V for North American models.
Maximum Efficiency: 96%. Dimensions: Approximately 565mm (H) x 320mm (W) x 149mm (D).
Connections: M8 battery terminals, M6 brass studs for AC connections.
Additional Features:
Pure sine wave output for clean, stable power.
Built-in anti-islanding for grid safety (MultiPlus-II models, but applicable to some MultiPlus configurations). Short-circuit proof and protected against overheating, reverse polarity, and other faults.
Supports integration with Victron control panels (e.g., Digital Multi Control, Color Control GX).
Key Differences from Victron Quattro 48/5000:The MultiPlus has one AC input, while the Quattro has two AC inputs (e.g., grid and generator) with automatic switching. The MultiPlus is generally more compact and cost-effective for systems not requiring dual AC inputs.
