The Victron Energy MultiPlus is a powerful true sine wave inverter, a sophisticated battery charger that features adaptive charge technology and a high-speed AC transfer switch in a single compact enclosure. The MultiPlus C, 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, plus multiple system integration features. The "C" stands for Compact. Unique PowerAssist feature The MultiPlus will prevent overload of a limited AC source, such as a generator or shore power connection. First, battery charging will automatically be reduced when otherwise an overload would occur. The second level will boost the output of a generator or shore-side supply with power taken from the battery. Uninterrupted AC power (UPS function) In the event of a grid failure, or when shore or generator power is disconnected, the inverter within the Multi is automatically activated and takes over the supply to the connected loads. This happens so fast (less than 20 milliseconds) that computers and other electronic equipment will continue to operate without disruption. Virtually unlimited power thanks to parallel operation Up to 6 Multis can operate in parallel to achieve higher power output. Three-phase or split-phase operation is also possible. Please check our datasheets to see which models have paralleling, three-phase, and split-phase capabilities. Remote Monitoring and Control When coupled with a GX device (e.g., Cerbo GX) you can monitor and control your Multi and system or systems locally (LAN) or remotely via the internet from anywhere in the world, using the free VRM app and free VRM portal website. Access can be from a phone, tablet, laptop, or PC for multiple operating systems. There is no end to the level of control, from adjusting your Multi to auto-starting a backup generator and more.
