MultiPlus-II 48/3000 35-50 120V The MultiPlus-II is a multifunctional inverter/charger with all the features of the MultiPlus, plus an external current sensor option which extends the PowerControl and PowerAssist function to 100A. PowerControl and PowerAssist - Boosting the Capacity of the Grid or a Generator  A maximum grid or generator current can be set. The MultiPlus-II will then take account of other AC loads and use whatever is extra for battery charging, thus preventing the generator or grid from being overloaded (PowerControl function). PowerAssist takes the principle of PowerControl to a further dimension. Where peak power is so often required only for a limited period, the MultiPlus-II will compensate insufficient generator, shore or grid power with power from the battery.When the load reduces, the spare power is used to recharge the battery. Solar Energy: AC Power Available Even During a Grid Failure  The MultiPlus-II can be used in off grid as well as grid connected PV and other alternative energy systems. It is compatible with both solar charger controllers and grid-tie inverters. Two AC Outputs  The main output has no break functionality. The MultiPlus-II takes over the supply to the connected loads in the event of a grid failure or when shore/generator power is disconnected. This happens so fast (less than 20 milliseconds) that computers and other electronic equipment will continue to operate without disruption. The second output is live only when AC is available on the input of the MultiPlus-II. Loads that should not discharge the battery, like a water heater for example, can be connected to this output. Virtually Unlimited Power Thanks to Parallel, Split Phase and Three Phase Operation  Up to 6 Multis can operate in parallel to achieve higher power output. Six 48/3000/35 units, for example, will provide 15 kW / 18 kVA output power with 210 Amps charging capacity. In addition to parallel connection, two units of the same model can be connected for a 240V split phase output, and three units of the same model can be configured for three phase output. But that’s not all: up to 6 sets of three units can be parallel connected per phase. On-Site System Configuring, Monitoring and Control  Settings can be changed in a matter of minutes with VEConfigure software (computer or laptop and MK3-USB interface needed). Several monitoring and control options are available: Color Control GX, Venus GX, Octo GX, CANvu GX, laptop, computer, Bluetooth (with the optional VE.Bus Smart dongle), Battery Monitor, Digital Multi Control Panel.

Quattro-II - 24/3000 - 70-50/50 - 2X 120V Similar to the MultiPlus-II 2x120V, the Quattro-II 2x120V is a combined inverter and charger specifically designed for standard North American 50A 120/240VAC split-phase applications. Additionally, it can accept two AC inputs and automatically connect to the active source. 120/240V Input and Output, or 120V Input and Output (Always 120V Output When in Inverter Mode) The two AC inputs can be supplied from a split-phase 120/240V source or a single-phase 120V source. When one of the AC sources is available, the Quattro will feed through the AC to its output. The output will therefore mirror the AC input. The inverter/charger connects to the neutral and the preferred input line (L1). The power needed to charge the batteries will therefore be drawn from L1. The Quattro switches to inverter operation when no AC source is available. The inverter output is 120V single-phase. In invert mode, the Quattro connects both output lines (L1 and L2) together to provide 120VAC to loads on either line. Any 240V loads will therefore be supplied only when the Quattro is supplied by a split-phase AC source. This prevents heavy loads such as water heaters or 240V air conditioners from discharging the battery. PowerControl and PowerAssist - Boosting the Capacity of the Grid or a Generator A maximum grid or generator current can be set. The Quattro will then take account of other AC loads and use whatever is extra for battery charging, thus preventing the generator or grid from being overloaded (PowerControl function). PowerAssist takes the principle of PowerControl to a further dimension. Where peak power is often required only for a limited period, the Quattro will compensate for insufficient generator, shore, or grid power with power from the battery. When the load reduces, the spare power is used to recharge the battery (available on L1 input only). Two AC Inputs and Two AC Outputs The Quattro can be connected to two independent AC sources, for example,shore-side power and a generator, or two generators. The Quattro-II will automatically connect to the active source. The main output has no-break functionality. The Quattro takes over the supply to the connected 120V loads in the event of a grid failure or when shore/generator power is disconnected. The transfer time of the L1 output is less than 18 milliseconds, so computers and other electronic equipment will continue to operate without disruption. The transfer time of the L2 output is longer: approximately 40 milliseconds. The second (auxiliary) output is live only when AC is available on the input of the Quattro. Loads that should not discharge the battery can be connected to this output. Virtually Unlimited Power Thanks to Parallel and Three-Phase Operation Up to 6 Quattros can operate in parallel to achieve a higher power output. In addition to parallel connections, three units of the same model can be configured for three-phase output. In multi-phase setups, L2 is disabled on all units. On-Site System Configuring, Monitoring and Control Settings can be changed in a matter of minutes with the VictronConnect app or VEConfigure software (computer or laptop and MK3-USB interface are needed). Several monitoring and control options are available: Cerbo GX, Color Control GX, laptop, computer, Bluetooth (with the optional VE.Bus Smart dongle), Battery Monitor, and Digital Multi Control Panel.

The MultiPlus-II takes over the supply to the connected loads in the event of a grid failure or when shore/generator power is disconnected. This happens so fast (less than 20 milliseconds) that computers and other electronic equipment will continue to operate without disruption. The second output is live only when AC is available on the input of the MultiPlus-II. Loads that should not discharge the battery, like a water heater, for example, can be connected to this output. Virtually Unlimited Power Thanks to Parallel, Split Phase, and Three Phase Operation  Up to 6 Multis can operate in parallel to achieve higher power output. Six 48/3000/35 units, for example, will provide 15 kW / 18 kVA output power with 210 Amps charging capacity. In addition to parallel connection, two units of the same model can be connected for a 240V split phase output, and three units of the same model can be configured for three-phase output. But that’s not all: up to 6 sets of three units can be parallel connected per phase. On-Site System Configuring, Monitoring, and Control  Settings can be changed in a matter of minutes with VEConfigure software (computer or laptop and MK3-USB interface needed). Several monitoring and control options are available: Color Control GX, Venus GX, Octo GX, CANvu GX, laptop, computer, Bluetooth (with the optional VE.Bus Smart dongle), Battery Monitor, and Digital Multi Control Panel. Remote Configuring and Monitoring  Install a Color Control GX or other GX product to connect to the internet. Operational data can be stored and displayed on our VRM (Victron Remote Management) website, free of charge. When connected to the internet, systems can be accessed remotely, and settings can be changed.

Quattro-II - 12/3000 - 120-50/50 - 2X 120V Similar to the MultiPlus-II 2x120V, the Quattro-II 2x120V is a combined inverter and charger specifically designed for standard North American 50A 120/240VAC split-phase applications. Additionally, it can accept two AC inputs and automatically connect to the active source. 120/240V Input and Output, or 120V Input and Output (Always 120V Output When in Inverter Mode) The two AC inputs can be supplied from a split-phase 120/240V source or a single-phase 120V source. When one of the AC sources is available, the Quattro will feed through the AC to its output. The output will therefore mirror the AC input. The inverter/charger connects to the neutral and the preferred input line (L1). The power needed to charge the batteries will therefore be drawn from L1. The Quattro switches to inverter operation when no AC source is available. The inverter output is 120V single-phase. In invert mode, the Quattro connects both output lines (L1 and L2) together to provide 120VAC to loads on either line. Any 240V loads will therefore be supplied only when the Quattro is supplied by a split-phase AC source. This prevents heavy loads such as water heaters or 240V air conditioners from discharging the battery. PowerControl and PowerAssist - Boosting the Capacity of the Grid or a Generator A maximum grid or generator current can be set. The Quattro will then take account of other AC loads and use whatever is extra for battery charging, thus preventing the generator or grid from being overloaded (PowerControl function). PowerAssist takes the principle of PowerControl to a further dimension. Where peak power is often required only for a limited period, the Quattro will compensate for insufficient generator, shore, or grid power with power from the battery. When the load reduces, the spare power is used to recharge the battery (available on L1 input only). Two AC Inputs and Two AC Outputs The Quattro can be connected to two independent AC sources, for example,shore-side power and a generator, or two generators. The Quattro-II will automatically connect to the active source. The main output has no-break functionality. The Quattro takes over the supply to the connected 120V loads in the event of a grid failure or when shore/generator power is disconnected. The transfer time of the L1 output is less than 18 milliseconds, so computers and other electronic equipment will continue to operate without disruption. The transfer time of the L2 output is longer: approximately 40 milliseconds. The second (auxiliary) output is live only when AC is available on the input of the Quattro. Loads that should not discharge the battery can be connected to this output. Virtually Unlimited Power Thanks to Parallel and Three-Phase Operation Up to 6 Quattros can operate in parallel to achieve a higher power output. In addition to parallel connections, three units of the same model can be configured for three-phase output. In multi-phase setups, L2 is disabled on all units. On-Site System Configuring, Monitoring and Control Settings can be changed in a matter of minutes with the VictronConnect app or VEConfigure software (computer or laptop and MK3-USB interface are needed). Several monitoring and control options are available: Cerbo GX, Color Control GX, laptop, computer, Bluetooth (with the optional VE.Bus Smart dongle), Battery Monitor, and Digital Multi Control Panel.

MultiPlus 24/2000 - 50-50 - 120V - VE.Bus UL Approved  The MultiPlus, as the name suggests, is a combined inverter and charger in one elegant package. Its many features include a true sine wave inverter, adaptive charging, hybrid PowerAssist technology, and multiple system integration features. Two AC Outputs The main output has no-break functionality. The MultiPlus takes over the supply to the connected loads in the event of a grid failure or when shore/generator power is disconnected. This happens so fast (less than 20 milliseconds) that computers and other electronic equipment will continue to operate without disruption.  The second output is live only when AC is available on the input of the MultiPlus. Loads that should not discharge the battery, like a water heater, for example, can be connected to this output (a second output is available on models rated at 3 kVA and more). Virtually Unlimited Power Thanks to Parallel Operation Up to six Multis can operate in parallel to achieve higher power output. Six 24/3000/70 units, for example, provide 15kW / 18kVA output power with 420 Amps of charging capacity. Three Phase Capability In addition to parallel connections, three units can be configured for three-phase output. But that’s not all: with three strings of six parallel units, a 45 kW / 54 kVA three-phase inverter and 1260 A charger can be built. Split Phase Options Two units can be stacked to provide 120-0-120 V, and additional units can be paralleled up to a total of 6 units per phase, to supply up to 30 kW / 36 kVA of split phase power. Alternatively, a split-phase AC source can be obtained by connecting Victron's autotransformer (see data sheet onwww.victronenergy.com) to a ‘European’ inverter programmed to supply 240 V / 60 Hz. Power Control - Dealing with Limited Generator, Shore Side or Grid Power The MultiPlus is a very powerful battery charger. It will therefore draw a lot of current from the generator or shoreside supply (nearly 20 A per 3 kVA MultiPlus at 120 VAC). With the Multi Control Panel, a maximum generator or shore current can be set. The MultiPlus will then take account of other AC loads and use whatever is extra for charging, thus preventing the generator or shore supply from being overloaded. Powerassist - Boosting the Capacity of Shore or Generator Power This feature takes the principle of PowerControl to a further dimension. It allows MultiPlus to supplement the capacity of the alternative source. Where peak power is often required only for a limited period, the MultiPlus will make sure that insufficient shore or generator power is immediately compensated for by power from the battery. When the load reduces, the spare power is used to recharge the battery. Four-Stage Adaptive Charger and Dual Bank Battery Charging The main output provides a powerful charge to the battery system by means of advanced ‘adaptive charge’ software. The software fine-tunes the three-stage automatic process to suit the condition of the battery and adds a fourth stage for long periods of float charging. The adaptive charge process is described in more detail on the Phoenix Charger datasheet and on Victron's website under Technical Information. In addition to this, the MultiPlus will charge a second battery using an independent trickle charge output intended for a main engine or generator starter battery. System Configuring Has Never Been Easier After installation, the MultiPlus is ready to go. If settings have to be changed, this can be done in a matter of minutes with a DIP switch setting procedure. Even parallel and 3-phase operations can be programmed with DIP switches: no computer is needed! Alternatively, VE.Net can be used instead of the DIP switches. And sophisticated software (VE.Bus Quick Configure and VE.Bus System Configurator) is available to configure several new, advanced features.
