Technical FAQs 4

How does a solar inverter compensate for irradiation intensity?

The inverter performs partial harmonic current compensation due to the solar irradiation intensity. The value of K under the partial harmonic compensation method is 0.86 (shown in Fig. 8 (a)). The grid current compensates for all harmonics according to a proportionality coefficient of 0.86; however, the THD remains high at 9.56 %.

How does a solar inverter perform harmonic current compensation?

In Scenario 1 (0.5 - 1.0 seconds), with low solar irradiation intensity, the inverter performs full harmonic current compensation, resulting in both K and K h values of 1. In Scenarios 2 (1.0 - 1.5 s) and 3 (1.5 - 2.0 s), as solar irradiation intensity increases, the inverter performs partial harmonic current compensation.
