INVERTER/CHARGER SYSTEM WITH INTELLIGENT SHORE AND GENERATOR POWER MANAGEMENT
PowerControl: Dealing with limited generator or grid power All models in the MultiPlus range feature powerful
battery chargers. When the largest model is working hard it can draw almost 10A from a 230V supply. Using the
remote panel it is possible to ‘dial-in’ the maximum current that is available from mains or generator. The MultiPlus
will then automatically regulate the charger taking account of other system AC loads and ensuring the charger only
uses what is spare. This way it is possible to avoid tripping the mains power or overloading the generator.
MULTIPLUS PRINCIPLE
PowerAssist: Boosting the power available from mains or generator, an innovative feature of Multiplus. The feature
that most distinguishes the MultiPlus from other inverter / chargers is PowerAssist. This feature takes the principle
of PowerControl to a further dimension by allowing a MultiPlus to supplement the power available from mains or
generator to ‘assist’ during periods of high demand. Peak power demand is almost always sustained only for short
periods, either a few minutes (in the case of items like cooking appliances) or just a few seconds (in the case of the
burst of energy needed to start an air-conditioning or refrigeration compressor).
With the capacity of the generator or mains power set on the remote panel, the MultiPlus detects when the load
is becoming too much for the supply and will instantly provide the extra power required. When the demand has
reduced, the unit returns to charging the battery. This feature is equally eective in large and small systems
helping to reduce the required generator capacity or to achieve greater things with limited mains power. There is
even a special feature to enable the MultiPlus/Quattro to work perfectly with portable generators.
Inverter boosts incoming power, if required, to avoid overload of supply when system consumption
exceeds supply.
Battery charger reduces its output, if required, to avoid overload of supply when system consumption is
high.
