MultiPlus 48/5000/70-100

The Victron Energy MultiPlus 48/5000/70-100 is an integrated power solution that combines a pure sine wave inverter, an adaptive battery charger, and an ultra-fast AC transfer switch in a compact housing. It is designed to manage and deliver power intelligently for various applications, including marine installations, recreational vehicles, or standalone energy systems.

The MultiPlus 48/5000/70-100 inverter provides a continuous output power of 5000 VA (4000 W) at 230 VAC and a frequency of 50 Hz.

The MultiPlus 48/5000/70-100 integrates an adaptive battery charger capable of delivering a maximum charging current of 70 amperes.

The AC transfer switch integrated in the MultiPlus 48/5000/70-100 has a capacity of 100 amperes.

Yes, the MultiPlus provides UPS (Uninterruptible Power Supply) functionality. In the event of a mains power failure or generator shutdown, it automatically and seamlessly switches to inverter mode to power connected devices without disrupting their operation.

The PowerControl function limits the battery charging current to prevent overloading a limited AC source, such as a generator or shore power connection. The MultiPlus takes other energy consumers into account and only uses the 'excess' current for charging.

The PowerAssist function extends the PowerControl principle by allowing the MultiPlus to supplement the capacity of a limited AC source. During power demand peaks, the device draws from the battery to compensate for the AC source’s shortfall. When the load decreases, excess power is used to recharge the battery, enabling the use of smaller generators or low-amp shore power connections for high-power equipment.

Yes, up to six MultiPlus 48/5000/70-100 units can be connected in parallel. This allows a combined inverter power of 30 kVA (24 kW) and a charging capacity of 420 amperes.

Yes, three units can be configured for a three-phase output. Additionally, up to six sets of three units (18 units total) can be connected in parallel to provide inverter power up to 72 kW / 90 kVA and charging capacity exceeding 1200 amperes.

Yes, the MultiPlus 48/5000/70-100 is perfectly suited for solar power applications. It can be used in both standalone systems and grid-connected systems.

The MultiPlus is supplied ready for use, but its parameters can be modified. Configuration options include using DIP switches for critical settings (including parallel and three-phase operation), a VE.Net panel for most settings (except the multifunctional relay), or a PC with the free software downloadable from the Victron Energy website.

Yes, the MultiPlus has two DC outputs for battery charging. The main DC output can provide the full output current, while a second output, intended for charging a starter battery, is limited to 4A and has a slightly lower output voltage.

Yes, the two programmable analog/digital input/output ports of the MultiPlus can be used to communicate with the BMS (Battery Management System) of a lithium-ion battery.

The MultiPlus 48/5000/70-100 is a Class I safety device. Its AC input and/or output terminals must have a continuous safety ground connection. An additional grounding point is also located outside the product.

Connection cables must be equipped with fuses and circuit breakers. Never replace a protection device with a different type of component and always refer to the manual for the correct part.

The equipment must be used under correct operating conditions. It must never be used in a damp or dusty environment. It is also essential to allow sufficient free space around the product for ventilation and to ensure that ventilation openings are not blocked. Installation must be carried out in a heat-resistant environment, ensuring that no chemicals, plastic parts, curtains or other textiles are located in the immediate vicinity of the equipment.

The microprocessor-controlled adaptive battery management system adapts to different battery types and their usage. It automatically adjusts the four-stage charging process (bulk, absorption, float, storage) to prevent overcharging, extend absorption time after deep discharge, and reduce float voltage in storage mode to minimize gassing and corrosion.

Yes, a temperature sensor is supplied with the product. It reduces the charging voltage when battery temperature rises, which is particularly important for maintenance-free batteries to prevent drying out due to overcharging.

The MultiPlus is equipped with a battery voltage sensing function (voltage sense). This function compensates for voltage drop caused by cable resistance by measuring the voltage directly at the DC bus or at the battery terminals, ensuring precise charging voltage.
