It describes the output voltage of an inverter, which converts direct current (DC) from sources like batteries or solar panels into alternating current (AC). The output voltage of an inverter is determined by the DC input voltage and the modulation index.
When selecting an inverter, it is essential to ensure that its maximum DC current specification meets the requirements of thin-film modules. The current of each MPPT-connected PV string should remain below the inverter’s DC current limit to prevent overcurrent damage.
In previous editions, we discussed two critical indicators on the PV side of an inverter: the maximum over-sizing ratio and the maximum PV input voltage. Now, we will take a deep dive into the remaining parameters on the PV side, analyzing them one by one.
1. Maximum Input Current Definition: The maximum operating current allowed to pass through the PV side of an inverter. The input current is especially critical in scenarios with high peak power currents, such as those involving thin-film PV modules.
