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
