PV magazine reports SolarEdge, Growatt have been found in breach of Swedish electromagnetic rules, some products have been banned from sale

The article says:

The Swedish Electrical Safety Agency has ruled that some SolarEdge optimizers and one string inverter from Growatt do not meet its electromagnetic compatibility (EMC) requirements – halting their sale in the country. SolarEdge expressed surprise at the banning and claims that the complaints filed with the Electrical Safety Agency came from a handful of amateur radio operators.

The Swedish Electrical Safety Agency has ruled that some SolarEdge optimizers and one string inverter from Growatt do not meet its electromagnetic compatibility (EMC) requirements – halting their sale in the country. The agency had recently inspected inverters and optimizers from eleven different PV power electronics suppliers. The inspections were carried out to check as to whether the equipment meet the country's electromagnetic compatibility (EMC) requirements

The agency found that three companies were not in compliance with Sweden's current EMC rules. As a result, the manufacturers were banned from selling the products that were found to be in breach in the country.

The inspection was triggered by several reports received by the electrical safety agency, in which photovoltaic systems were said to have disrupted the radio communications of the police, aircraft, and the military.

The ban applies to Israel-based power electronics supplier SolarEdge for a number of its optimizers. Chinese manufacturer Growatt was also found to have fallen foul of the regulators, for its 8000TL3-S inverter series, which in Sweden are distributed by Sunnytek Solar Sweden AB, and a second company that has not been identified yet.

Interesting.

Having a Solar Edge inverter I find no problems whatsoever with any interference problems which could be attributed to it. However it is pleasing to note that some authorities (take note OFCOM) do check on the standards set and do take action.

I must admit that i am not shocked by the news that these items made in China failed the emc test. I would be shocked if any electrical item produced in China actually passed an emc test.

My neighbours Sunsynk inverter produces -85dBm noise spikes every 30KHz across the entire HF spectrum.
