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 ‘Charger’ LED will light up and the charger commences charging. 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 also is switched through to the ‘AC out’ terminal.
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 the batteries from running flat.
3.2. Remote control
Remote control is possible with a switch or with a Multi Control panel. The Multi Control panel has a simple rotary knob with which
the maximum current of the AC input can be set: see PowerControl in Section 2.

Inverter/Charger
On / Off / Charger-only switch = On
The inverter is switched on and supplies power to the load.
On / Off / Charger-only switch = Charger only
The inverter is switched on and supplies power to the load.
Pre-alarm: overload, or
battery voltage low, or
inverter temperature high
On / Off / Charger-only switch = On
The inverter is switched off due to one of the following alarms:
overload, or
battery voltage low, or
inverter temperature high, or
DC ripple voltage too high.
