• To work safely, please disconnect the inverter from the 230V power supply, then disconnect your solar panels.

• Disconnect the solar panels by pressing on the MC4 connectors and pulling on the connectors.

• Make sure that solar panel is not dirty or damaged. A dirty solar panel can lose up to 15% of production.

The solar panels can be cleaned with lukewarm water and a soft cloth. Do not use detergents. Do not scratch the surface of panel to avoid scratching the surface glass.

• Check that every weld line connecting the cells is perfectly straight.

• In the event of a power cut or damage to solar panel, production will be affected to a greater or lesser extent.

• Position your solar panel in full sunlight.

• Use a multimeter to check the voltage of each solar panel.
• Configure your multimeter to measure a 20Vdc voltage.

• Connect the Volt terminal of your multimeter to the “+” connector of the solar panel.
• Connect the Gnd terminal on your multimeter to the “-” connector on solar panel.
• In full sunlight and with no load, each solar panel should supply 10.7Vdc.

• Reconnect each solar panel to the inverter, and then reconnect the inverter to your 230V outlet.
• Wait about 3 minutes for your inverter to start up.
• Then launch your AvidsenHome application

• On the SORIA kit home page, click on “PV puissance”.

• The “Photovoltaic voltage” value corresponds to the voltage supplied by your solar panels. With 4 compliant solar panels, you should have a value of 34V
• The “Photovoltaic current” value corresponds to the current produced by your solar panels. This value will depend on the positioning of your solar panels and the sun’s light output. A good exposure should be around 10A.

Example of a solar panel that is poorly connected or faulty

• Photovoltaic voltage is incorrect
• Photovoltaic current is correct

Incorrect exposure or low light intensity

• Photovoltaic voltage is correct
• Photovoltaic current is incorrect

It’s normal to have these values in autumn and winter.
