Operation; Remote Control - Victron energy MultiPlus 12/3000/120 – 50 Manual

3. OPERATION

3.1 On/Off/Charger Only Switch
When switched to "on", the product is fully functional. The inverter will come into
operation and the LED "inverter on" will light up.
An AC voltage connected to the "AC in" terminal will be switched through to the "AC
out" terminal, if within specifications. The inverter will switch off, the "mains on" LED
will light up and the charger commences charging. The "bulk", "absorption" or "float"
LEDs will light up, depending on the charger mode.
If the voltage at the "AC-in" terminal is not within specifications, the inverter will switch
on.
When the switch is switched to "charger only", only the battery charger of the
MultiPlus will operate (if mains voltage is present). In this mode input voltage also is
switched through to the "AC out" terminal.
NOTE: When only the charger function is required, ensure that the switch is switched
to "charger only". This prevents the inverter from being switched on if the mains
voltage is lost, thus preventing your batteries from running flat.

3.2 Remote control

Remote control is possible with a 3-way switch or with a Phoenix Multi Control panel.
The Phoenix Multi Control panel has a simple rotary knob with which the maximum
current of the AC input can be set: see PowerControl and PowerAssist in Section 2.
3.3 Equalisation and forced absorption
3.3.1 Equalisation
Traction batteries may require regular equalisation charging. In the equalisation
mode, the MultiPlus will charge with increased voltage for one hour (1V above the
absorption voltage for a 12V battery, 2V for a 24V battery). The charging current is
then limited to 1/4 of the set value. The "bulk" and "absorption" LEDs flash
intermittently.
Equalisation mode supplies a higher charging voltage than most DC consuming
devices can cope with. These devices must be disconnected before additional
charging takes place.
3.3.2 Forced absorption
Under certain circumstances, it can be desirable to charge the battery for a fixed time
at absorption voltage level. In Forced Absorption mode, the MultiPlus will charge at
the normal absorption voltage level during the set maximum absorption time. The
"absorption" LED lights.
