With the recent residential installations of Tesla’s Powerwall home battery systems, customers have been reporting an unwanted loud electronic humming sound .
Breitbart.com reported, “a German customer measured a noise level from a Powerwall installed in his garage in February at more than 80 decibels,” which was continuous and audible “in the whole house.”
“I was told that the power consumption of the ventilation or cooling system was reduced to 15 percent of its original value,” said the customer when Tesla sent one of its “ranger” technicians to address the issue, “After this update, the noise was not there anymore.”
However, Breitbart.com warned that “since Tesla’s Powerwalls use a radiator liquid cooling system, slashing the cooling capacity to cut the noise issue would seem to risk damage to the equipment and limit Powerwall’s performance capability.”
