EMI occurs during the flow of electrons in many devices, including PV inverters. The level of EMI generated by PV inverters must be below a certain level for many important reasons since high levels of EMI can disrupt the functioning of many critical operations including air traffic control, military applications, and other communications.
EMI values 16x higher than legally allowed
Our testing of a competitor’s inverters revealed that, in many instances, the levels of EMI were far above the permissible limits of regulation EN 6100-6-3:2011. We found that peak values were measured at 65 dBμV/m, which is more than sixteen times above the allowable threshold . However, our competitor claims an unwarranted conformity, with all legal requirements and relevant technical standards, by placing a “CE” mark on their nameplates and product documentation.
