9.2.1 Check the Ventilation
In operation the Sunny Central is cooled by fans in case the temperature exceeds a defined threshold.
In the Power Cabinet, the air is sucked in from the top front and expelled at the bottom in the back.
Check the ventilation air flow using a sheet of paper.
1. Hold the piece of paper in front of the air shafts.
2. Check to see whether the sheet is blown away from or sucked toward the inverter.
