High pitched noise from Sunsynk 5 kW inverter

Recommended Posts

Commissioned a Sunsynk 5kW inverter this evening, there is a high pitched noise emanating from the inverter, which also coming from tv, Xbox, a ups, etc, if the grid is switched off and the load is running on batteries, there is no noise

   Firmware version is 2138

Also had this when I initially commissioned mine. With the cover plate on it was less annoying.

At some point I had switched off the inverter completely and disconnected the batteries.

When I turned on everything again, the pitch was really bad.

After a few days I decided to just switch it off with the power button underneath the inverter - did not switch off anything.

When I switched it back on, the pitch was virtually gone (it is there but really really faint only audible when I get your ears in really close).

Not a technical solution but just what I experienced.

Vassen mentioned that it was worse with a certain firmware upgrade and then improved thereafter again...
