Powerhouse II 400 High Frequency sound when charging via Solar panel

#1

Hi,

I wanted to see if anyone else has come across this issue. I’ve got a Powerhouse II 400 and have noticed that when charging from my Solar panel ( ECO-WORTHY 130Watt 12 Volt Flexible Monocrystalline) I am getting a high-frequency sound from the unit, which may be coming from the area around the DC-in connector.

Has anyone else come across this issue?

Thanks,

Andy

Hello. Yes. I am having this problem. I notice it was some time ago that you posted this enquiry. Did you manage to resolve the noise.
