Fault Kostal Piko DSC 3.6 -idle-?

[ronniee]

Hi,

We have buyed a Kostal Pico DSC 3.6 inverter 3 years ago. And doesn't work since couple month ago.
The unit is start correctly but remain in "idle" mode. The big capacitors are ok. Display "idle" not fault error. It display the AC voltage, but no DC voltage.
We measured the DC voltage on the cable and is OK 500W and 0.7A on a cloudy morning.
This voltage enter in the device and is measured in the middle left part, but doeasn't flow next.

Maybe this kind of problem has appeared at other user/devices, so if you know the solution please send me some advice.
Or repair instructions.

thanks
ronn

Sounds like it may be an issue with the DC switch. Have you phoned Kostal?

You need 380 volts dc minimum for it to start looking at the data sheet
