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.
