2.2 Inverter
MultiPlus Compact-functional
The MultiPlus Compact gets its name from the multiple functions it can perform. It 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.
Beside these primary functions, however, the MultiPlus Compact has several advanced
features that provide a range of new applications as outlined below.
Uninterrupted AC power
In the event of a grid failure, or shore or generator power being disconnected, the inverter
within the MultiPlus Compact is automatically activated and takes over 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.
PowerControl – Dealing with limited generator or shore side power
With a Multi Control Panel a maximum generator or shore current can be set. The MultiPlus
Compact will then take account of other AC loads and use whatever is extra for charging,
thus preventing the generator or shore supply from being overloaded.
PowerAssist – Boosting the capacity of shore or generator power
This feature takes the principle of PowerControl to a further dimension allowing the MultiPlus
Compact to supplement the capacity of the alternative source. Where peak power is so often
required only for a limited period, it is possible to reduce the size of generator needed or
conversely enable more to be achieved from the typically limited shore connection. When the
load reduces, the spare power is used to recharge the battery.
Programmable relay
The MultiPlus is equipped with a programmable relay that by default is set as an alarm relay.
The relay can be programmed for all kinds of other applications however, for example as a
starter relay for a generator.
2.3 Battery Charger
Adaptive 4-stage charge characteristic: bulk – absorption – float – storage
The MultiPlus Compact features a microprocessor controlled 'adaptive' battery management
system that can be preset to suit different typs of batteries. The 'adaptive' feature will
automatically optimize the process relative to the way the battery is being used.
The right amount of charge: variable absorption time
When only shallow discharges occur (a yacht connected to shore power for example) the
absorption time is kept short in order to prevent overcharging of the battery. After a deep
discharge the absorption time is automatically increased to make sure that the battery is
completely recharged.
