3. Operation

In this section:

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.

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 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 = On 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.
	On / Off / Charger-only switch = On The AC input voltage is switched through and the charger operates in float mode.
	On / Off / Charger-only switch = On. PowerControl and PowerAssist: The AC input is switched through and the charge current is zero. The inverter is switched on and, in case of PowerAssist, assists the AC input by supplying additional power to the load (see section 2.1).
	On / Off / Charger-only switch = On. Energy Storage System (ESS): The AC input voltage is switched through. The inverter is switched on and supplies power to the load, or excess power to the mains.
