5. Setup and Installation
Installation of the SolarEdge inverter should only be performed by certified professionals. This section provides a general overview of the installation process.
5.1 Mounting the Inverter
- Choose a suitable mounting location that is protected from direct sunlight and extreme weather conditions. The inverter is rated for both outdoor and indoor installation (NEMA 4X).
- Ensure adequate clearance around the inverter for proper ventilation and heat dissipation.
- Mount the inverter securely to a sturdy wall or structure using appropriate hardware. The unit is significantly lighter (approx. 25 pounds) due to HD-Wave technology, simplifying installation.
5.2 Electrical Connections
- Connect the DC input from the SolarEdge DC optimizers to the inverter's DC input terminals.
- Connect the AC output of the inverter to your electrical panel or grid connection point.
- Ensure all wiring is correctly sized and protected according to local electrical codes.
- Verify all connections are tight and secure before powering on the system.
5.3 System Commissioning
- Commissioning can be done quickly and easily using the SolarEdge SetApp mobile application.
- Follow the on-screen prompts in the SetApp to configure the inverter and connect it to the monitoring platform.
6. Operating the Inverter
Once installed and commissioned, the SolarEdge inverter operates automatically, converting solar DC power to AC power for consumption or export to the grid.
6.1 Powering On/Off
- To power on the inverter, ensure the DC and AC disconnects are in the ON position. The inverter will initiate its startup sequence.
- To power off the inverter, first turn off the AC disconnect, then the DC disconnect.
