MultiPlus system with 2 AC sources and transfer switch
When using an external transfer switch (VE Transfer Switch) with a MultiPlus inverter/charger system, the switch dictates which AC source is utilised - either generator or grid power. However, the control panel itself is not aware of the chosen AC source.
To ascertain the transfer status, the control panel features a screw connector on its backside. Normally, the panel sends the AC current set point from the knob to the inverter/charger system. But, by short-circuiting the screw terminals, the panel displays "GEN" and sends a preset AC current limit to the inverter/charger system.
For connection advice refer to the External transfer switch connection chapter and for configuration instructions, refer to the Generator current limit chapter.
