Our quality control procedures begin with freezing all of our assembled printed circuit boards below 0° C, then we heat the boards to over 80° C.
We then inspect the boards through a process called in-circuit testing for any soldering imperfections the boards may have incurred during the wave soldering process.
After the inverters are assembled with the printed circuit boards and other components, they are placed in a chamber. The inverters are frozen to below 0° C.
After the freezing process the inverters are moved to another chamber that is heated to over 70° C. We run inverters at full rated power for the final extreme stress test prior to shipping.
KACO inverters worldwide have less than 1% failure rates in the field because of our extreme quality control measures. We test EVERY INVERTER as described above, before they leave the factory. That’s Cool!
