MultiPlus-II inverter/charger off-grid Australia
3. Operation
3.1. On/off/charger-only switch
When switched to 'on', the MultiPlus-II is fully functional. The inverter will come into operation, and the LED 'inverter on' will light
up.
An AC voltage connected to the AC input terminal will be switched through to the AC output 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 rejected, the inverter will switch on.
When the switch is switched to 'charger only', only the battery charger of the MultiPlus-II will operate (if an AC voltage is present).
In this mode, the AC input voltage is also 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 AC input voltage is lost, thus preventing your batteries from running flat.
3.2. Remote control
The product can be remotely controlled in two ways.
• With an external switch. For the switch to operate the switch on the Multiplus-II needs to be set to "on".
• With a
Digital Multi Control
panel. For the panel to operate the switch on the Multiplus-II needs to be set to "on".
3.3. GX card and LCD interface
The display screen will present useful information about your system.
3.3.1. On/Off behaviour
When the product is switched off with the physical switch on the device or with the Remote On/Off terminals, then the GX card
is off as well. If you switch the product remotely, using a Digital Multi Control, then the GX card will remain powered. Also when
switching the inverter/charger off from within the GX menus, the GX card will remain powered.
Lastly, when the inverter/charger switches itself off due to an alarm, such as low battery or overtemperature, then the GX card will
remain powered and functional as well.
3.3.2. Push button behaviour
When the GX Card is on, pushing the button beside the screen will increase the brightness of the backlight. The backlight will dim
itself again after 5 minutes.
Once the backlight has been activated, pushing the button again will cycle through the available display options. Some options
will be displayed automatically, and others require a button push to display.
3.3.3. Information displayed
• Solar Power, Voltage and Charge state (if connected)
• Solar Daily Yield
• Inverter/charger charge state
• Battery State of Charge, Power and Voltage
• Network IP Address and Connection Type (if connected).
• AC input and output Power
In a system with more than one phase, there will be additional AC input and output information available, eg
• Phase 1 AC input Voltage and Power.
• Phase 1 AC output Voltage and Power
• Phase 2 AC input Voltage and Power.
