Page 8: Operation
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 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’... - Page 9 MultiPlus-II inverter/charger off-grid Australia Overload alarm The inverter is switched off due to overload or short circuit. The "overload" LED is on. Low battery pre-alarm The battery voltage is getting low. The battery is almost fully exhausted. The "low battery"LED is blinking. Low battery alarm The inverter has switched off due to low battery voltage.
- Page 10 MultiPlus-II inverter/charger off-grid Australia Ripple pre-alarm The ripple voltage on the battery terminals is too high. The "overload" and "low battery" LEDs are both blinking simultaneously. Ripple alarm The inverter has switched off due to excess ripple voltage on the battery terminals.

Page 11: Equalisation And Forced Absorption
MultiPlus-II inverter/charger off-grid Australia Equalize charging The mains voltage is switched through and the charger operates in equalize mode. The "bulk" and "absorption" LED are both blinking. PowerControl The AC input is switched through. The AC output current is equal to the preset maximum input current. The charge current is reduced to 0A. -
Page 12: Activating Equalisation Or Forced Absorption
MultiPlus-II inverter/charger off-grid Australia 3.4.3. Activating equalisation or forced absorption The MultiPlus-II can be put into both these states from the remote panel as well as with the front panel switch, provided that all switches (front, remote, and panel) are set to ‘on’ and no switches are set to ‘charger only’. In order to put the MultiPlus-II in this state, the procedure below should be followed. -
