Bluesolar PWM error

Hi all,

I have done a search but can't find an answer relevant.

I have a BlueSolar Charge Controller-LCD-USB 12V-20A.

It has started showing a flashing error message L5C (or maybe LSC) as shown in the image below. "L" in the manual relates to the output load and sunset etc which doesn't appear relevant.

It doesn't appear in the error codes listed in the manual and I can't see anything useful on Google. It also doesn't appear to have any issues with the operation as it takes charge from the panels, and the loads which come via this unit.

Thanks for any help which can be offered.

I Dont have a answer to your question however try this


connect a bluetooth dongle to the unit and upgrade its firmware to the latest version and then see what happens.

you will also get a lot of extra information using the bluetooth unit as wel through the Victron Connect app.

you can install the app and run it in dem mode and see the extra things it has to offer

The PWM charge controllers don't have a VE.direct port.

The error is LSC, I assume it means Load Short Circuit.

See page 9, https://www.victronenergy.com.au/upload/documents/Manual-BlueSolar-PWM-Charge-Controller-LCD&USB-12V-24V-5A-10A-20A-EN-NL-FR-DE-ES-SE-IT.pdf.
