Equipped with PowerControl and PowerAssist technology, the MultiPlus-II intelligently manages available power from generator, shore, or grid sources, preventing overload by supplementing peak demands with battery power when needed – and automatically recharging when demand drops. An external current sensor extends input management up to 100A, enabling greater flexibility in power-limited environments.
Built to meet UL 458 certification standards, this unit ensures safe, efficient, and reliable performance in both mobile and stationary applications – delivering intelligent power management and uninterrupted energy wherever you need it.
