PID KILLER exceeds all expectations

Press release / Kitzingen

PR improvement of more than 13% within one month.

PID KILLER exceeds all expectations - PR improvement of more than 13% within one month.

Module degradation due to PID and the economic loss caused by this effect are serious problems that have arrived in the middle of PV business and which everybody is talking about.

PADCON Float Controller offers a unique alternative. It allows the operation of an ungrounded system and simultaneously fights the PID-effect. Technically it is realized with an active lifting of the positive potential. Based on the fact that modules do not see negative voltage to ground anymore PID affected modules will be regenerated and prevented from happening in the future.

PADCON Float Controller proves its abilities now - black on white. With a current test series it was installed in a 3 MW PV plant in Israel. The test plant having poly-cristalline modules showed a massively decreasing performance caused by PID. In order to test the efficiency of the device only one inverter position was equipped with PADCON Float Controller. It was connected to the 5 DC inputs (5 MMPTs) of the central inverter. This was realized in a cost-efficient way using PADCON Multi Connector. Shortly after installation there were effects of regeneration already and after 42 days only the affected PV modules have been free from PID.

Long-term protected by Float Controller the PV plant generates its predicted yield (PR 84,11%) again. Thanks to the intelligent combination of Float Controller and Multi Connector this investment amortized after less than 3 months already.

Detailed test results can be found in our flyer.
