The MAX-X2 and MAX-XL2 series inverter works as follows:
1>Photovoltaic panels collect solar energy to generate direct current to the inverter.
2>With inrush current detection circuit, it can monitor the working status of all PV panels and use MPPT to track the maximum power point.
3>The inverter circuit changes power from DC to AC and returns power to the grid based on the grid’s requirements.
4>With output isolation relay can isolate AC output and grid, if something goes wrong on either inverter or grid side, isolation relay can disconnect inverter immediately.
