2. OPERATION
2.1 On/Off/Charger Only Switch
When the front switched to "on", the product is fully functional. The inverter will come into
operation and the LED "inverter on" will light up.
Multi Compact/ MultiPlus Compact only:
An AC voltage connected to the "AC in" connector will be switched through to the "AC out"
connector, if within specifications. The inverter will switch off, the "charger" LED will light up
and the charger commences charging. The "charger" LED will light up depending on the
charger mode (on=bulk, absorption) or (blinks=float).
If the voltage of the "AC-in" terminal is too high or too low, the AC input voltage will switch off
and the inverter will be starting.
When the front switch is switched to "charger only", only the battery charger of the Phoenix
Multi Compact 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.
2.2 Remote Operation
The Phoenix Multi Compact can be operated with the Phoenix Multi control panel. The
remote control has an on-off switch and more indication.
The charger of the Phoenix Multi Compact can be turned off. This can be done by changing
the set up configuration by connecting the Phoenix Inverter remote control (set the AC input
current to 0) or by connecting a computer to the Phoenix Multi Compact (use MK.1 with
VEConfigure).
For remote control of the Phoenix Inverter Compact the Phoenix Inverter control panel
should be used.
2.3 Special Charger Modes Equalizing
Some batteries may need a regular equalizing charge. To perform an equalizing charge the
Phoenix Multi Compact can charge at a higher voltage (1V above the absorption voltage for a
12V battery, 2V for a 24V battery) for a period of one hour. The charger current is then limited
to 1/4 of the specified value.
The "bulk" and "absorption" LEDs will flash alternately during this cycle (only on Phoenix Multi
Control).
The equalizing mode results in a charging voltage that may exceed the
maximum voltage of DC consumers. These should be disconnected when
performing an equalizing charge.
