Incorporating all the features of the MultiPlus inverter and charger combinations, the Multiplus II adds an external current sensor option to enable the PowerControl and PowerAssist functions to extend to 50A and 100A respectively. It can be used in off-grid as well as grid-connected PV and other alternative energy systems and is compatible with both solar charger controllers and grid-tie inverters. Added to this, with many countries approving the unit for ESS application this unit is able to feed back into the grid, any power excess to requirements.

Other features include:

• True sine wave inverter
• Adaptive charging
• Hybrid PowerAssist
• PowerControl
• Multiple system integration

PowerControl is a valuable feature, especially when handling limited power such as generator supply. When the Quattro draws significant current from the generator or shore side supply, set the maximum current limit on each AC input. Considering other loads, the Quattro adapts so that only surplus power is used for charging, thus preventing the generator or mains supply from being overloaded.

The PowerAssist feature will enable the device to supplement the incoming power with power from the battery. Any excess power is used for charging. It is therefore no longer necessary to size a generator on the maximum peak load. Use the most efficient size generator instead.

The advanced ‘adaptive charge’ software fine-tunes the three-stage automatic process to suit the battery condition and how the battery is being used, preventing damage and ensuring less maintenance is required. A fourth stage charge [also called the Storage mode] delivers a longer period of float charging. In addition, the Multiplus will charge a second battery using an independent trickle charge output.

Should there be a grid failure the UPS capability of the inverter is automatically activated. With some units having the ability to enable 6 Multis operating in parallel there is potentially close to uninterrupted and unlimited power.

If three phase power is required, then multiple units can be connected in parallel and configured with the combinations delivering up to 75KW/90 kVA inverter and more than 2000 Amps charging capacity.

Configuring parallel and three-phase systems is made simple with the VE.Configure software tool which allows the installer to put components together without any hardware changes or dipswitches, using standard products.

Monitoring and configuring functionality offers seamless control, both on-site and off-site.
