Victron energy Phoenix Multi Compact 12 / 800 / 35 Bedienungsanleitung, Montageanleitung Seite 23

4.5 Special Settings (can be changed with VEConfigure only)
Bulk Protection On / Off (default: on)
If the charger has not reached the absorption voltage after 10 hours' charging in the bulk
phase, the battery may be defective. In order to prevent further damage, the charger will
automatically cut out after 10 hours' bulk. The "bulk" LED will start to flash (Phoenix Inverter
Control).
AC Waveform Check (default: on)
The Phoenix Multi Compact checks if the mains voltage has not only the correct voltage, but
also the correct shape. When the Phoenix Multi Compact does not function properly on
a generator this function can be disabled.
Note: Additionally, by disabling AC waveform check the AC low disconnect is ignored when
the load current is higher than 1.5 times the AC input current limit. This to prevent
unnecessary switching to inverter due to a voltage drop when a high load is connected.
PowerControl – Dealing with limited generator or shore side power
The Multi Compact is a very powerful battery charger. It will therefore draw a lot of current
from the generator or shore side supply. With the Phoenix Multi Control Panel (PMV) 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. It is also possible to set the max. generator/ shore current
internally. The generator/shore current limit can be set at from 2 to 16A.
The remote control panel setting overrides the internal setting.
PowerAssist – Boosting the capacity of shore or generator power (MultiPlus only,
default: on)
The feature that distinguishes the Phoenix MultiPlus Compact from the standard Multi
Compact is PowerAssist. 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.
Note 1: Minimum shore current 2 A or generator capacity equal to the Multi rating required for
proper operation of PowerAssist.
Note 2: Some modern AC generators use a static inverter to generate the AC output. Some
of these generators also reduce rpm when operating with reduced load. By enabling the
Dynamic Current Limit function (VEConfigure) the MultiPlus Compact can be used to assist
the generator when suddenly a high load is connected.
External Alarm Relay and Virtual Switch (default: disabled)
An open collector output is available to connect a relay that can be used for remote alarm and
other purposes (a. o. generator start signal).The maximum voltage/current that can be
switched (open collector transistor): 66V 40mA.
The open collector output can be programmed with VEConfigure.
4.6 Maintenance
The Phoenix Multi Compact does not require specific maintenance. Annual checking of all
connections and eventually removal of dust suffices. Protect the product from humidity and oil
fumes and keep it clean.
