Victron Energy MultiPlus-II GX 48V 5000VA 70A - 50A inverter / charger

Product detailed description

The MultiPlus-II GX is a multi-function inverter/charger with an integrated GX unit, with the option to connect an external current sensor to extend the PowerControl and PowerAssist functions, ideal for use in island and ESS systems. It also has all the features of the MultiGrid unit with built-in anti-islanding protection on its AC input - enhanced protection to prevent unwanted supply to the distribution network in the event of a grid failure. Main features: The MultiPlus-II GX, compared to the MultiPlus II, additionally includes a GX device and a 2 x 16 character display. The display shows the parameters of the solar controller and inverter. The same parameters can be accessed using a smartphone or other Wi-Fi enabled device. The integrated GX device (similar to the Venus GX device) includes: - VE.Can interface - USB port - Ethernet port - VE.Direct port PowerControl and PowerAssist MultiPlus-II prevent overloading of a power-limited AC source, e.g. a current-limited power connection or generator. Should a large draw overload the input AC source, the charging current to the battery (PowerControl) will be automatically reduced in the first step. 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. One AC input The MultiPlus-II is equipped with one AC input for connection to the distribution network or, for example, to a generator. If two AC inputs are required, then select 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. Virtually unlimited power due to parallel and three-phase operation Up to 6 MultiPlus-II units can operate in parallel to achieve higher performance. Three units of the same type can be configured for three-phase operation with phase shifting. 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. The MultiPlus-II 8k, 10k and 15k models can only be connected in parallel if an external AC transfer switch is used. For more information, refer to the MultiPlus-II External Transfer Switch Application Guide. ESS: Energy Storage Systems The MultiPlus-II is a key element in Victron Energy's ESS system, providing the flexibility to combine with solar MPPT controllers or grid-tied PV inverters. Configuration, monitoring and control of the system locally Settings can be changed using the VEConfigure software (PC or laptop and MK3-USB interface required). Four phase charging by an adaptive charger with two outputs for battery charging The main DC output provides powerful full battery charging via the "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. MultiPlus-II is designed to charge all types of lead acid, alkaline and lithium batteries. 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-tied 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 software you will need the PC communication interface MK3-USB.
