Inverter loss

[Manel]

Hello,

We checked the help section and we couldn't find the way to calculate inverter loss, we would very grateful if we get help to know the exact formula to determine inverter loss.

In addition, with many simulations, we get inverter loss 0, so how is that calculated?

Best regards,

The inverter losses are explained in the help under the topic 'Physical models used > Grid inverter > Inverter Operating Limits'.

There is no exact formula for these losses. The inverters are modeled as explained in the mentioned page, and the arising losses are added up throughout the simulation.

The most common loss, apart from the efficiency, is the  'Inverter Loss over nominal inv. power', which corresponds to clipping for overpower.

The other losses are normally zero or close to zero. Non-zero values would be an indication of a non-optimal design.
