Battery Charger - Victron energy MultiPlus Compact 12/2000/80 Manuel

2. DESCRIPTION
2.1 General
Multi 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 Multi 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 Phoenix Multi Control Panel a maximum generator or shore current can be
set. The Multi 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.

2.2 Battery charger

Adaptive 4-stage charging characteristics: bulk – absorption – float – storage
The microprocessor-driven adaptive battery management system can be adjusted for various
types of batteries. The adaptive function automatically adapts the charging process to battery
use.
The right amount of charge: variable absorption time
In the event of slight battery discharge, absorption is kept short to prevent overcharging and
excessive gas formation. After deep discharging, the absorption time is automatically
extended in order to fully charge the battery.
