Victron Energy MultiPlus-II 12V/3000VA/120A-32A inverter/charger

Product detailed description

MultiPlus plus + ESS (Energy Storage System) function The MultiPlus-II is a multifunctional inverter/charger with all the features of the MultiPlus and the option of an external current sensor that extends the PowerControl and PowerAssist functions to 50A and 100A respectively. The MultiPlus-II is ideal for professional marine, yachting, transportation and islanding applications off the grid. It also has a built-in anti-islanding protection function and is therefore also suitable for hybrid ESS applications. The MultiPlus-II is a key element in the Victron ESS system, providing the flexibility to be combined with solar MPPT controllers or grid-tied PV inverters. One AC input The MultiPlus-II is equipped with one AC input for connection to the distribution network or, for example, a generator. If two AC inputs are required, then choose the Quattro unit. Two AC outputs The MultiPlus-II is equipped with two AC outputs. The main AC1 output ensures power supply without power interruption. For example, in UPS mode, the MultiPlus-II will take over power to connected appliances (in less than 20 milliseconds) in the event of a mains or generator failure. The second AC output is only functional when the AC input (distribution network/generator) is available. Therefore, a load that would quickly drain the batteries, such as a water heater, can be connected to this output and it will only be powered from the AC source. Four phase charging by an adaptive charger with two outputs for battery charging. The main DC output provides powerful full battery charging through an "adaptive charging" system. The software controls the three-stage automatic charging process to suit the condition of the battery, and adds a fourth charging stage - maintenance charging. In addition to this, the MultiPlus-II can also charge a second battery using an independent charging output designed, for example, for generator starter batteries with a maximum charging current of 4 A. The MultiPlus-II is designed to charge all types of lead acid, alkaline and lithium batteries. Virtually unlimited power thanks to parallel operation Up to 6 MultiPlus-II units can operate in parallel to achieve higher performance. Three-phase operation Three units of the same type can be configured for three-phase operation with phase shift. But that's not all, up to 6 units in parallel can form a single phase. A three-phase system can thus consist of up to 18 units. Unique features of PowerControl and PowerAssist MultiPlus-II prevents overloading of a power-limited AC source, e.g. a current-limited power connection or generator. Should a large draw overload the AC input source, the charging current to the battery will be automatically reduced in the first step (PowerControl). The energy for charging is shifted to power the AC appliances. In the second step, the input AC source is boosted by the current drawn from the battery (PowerAssist). The AC output receives energy from the AC source and the battery (inverter) together. Solar energy AC power can be available even in the event of a grid failure. MuliPlus-II can be used in off-grid (islanded) systems as well as in PV systems permanently connected to the distribution grid. The MultiPlus-II is not equipped with a PV array input, but is designed to work with MPPT controllers (DC coupling systems) or grid-tied inverters (AC coupling systems) located at the AC input and/or AC output. System configuration - In the case of a simple e.g. UPS installation, setup can be easily done in a few minutes using the DIP switches on the MultiPlus-II or the VE.Configure 3 software and a PC. - Parallel and three-phase applications can be configured using VE.Bus Quick Configure software (up to three units) or more complex systems using VE.Bus System Configurator software (above three units) and a PC. - Off-grid and hybrid PV installations to support self-consumption and greater energy independence, which include grid inverters and/or solar MPPT chargers, can be configured using VE.Configure 3 software with the appropriate assistants (dedicated functions for specific applications). - MultiPlus-II has several programmable relays and auxiliary contacts for a variety of additional functions - You can download the basic VE.Configure 3 software as well as other software for configuration options free of charge at the following link: https://www.victronenergy.com/support-and-downloads/software For the above mentioned software you will need a PC communication interface MK3-USB. Remote monitoring and system configuration Monitor and control your system locally or remotely over the internet from anywhere in the world using the free VRM app and the free VRM portal: https://vrm.victronenergy.com/landingpage Access can be from a phone, tablet, laptop or PC for different operating systems. For remote access, you need one of the following control panels and then you have the option of monitoring and configuring the system from anywhere in the world: Cerbo GX Color Control GX Venus GX
