Pwm light 20a no longer in taking solar

I have a 200w solar panel connected to my pwm light 12v 20a and it was working fine. The light was flashing indicating power coming from the solar panel and into the battery but now the solar input light is showing nothing even though I know there is 19v coming from the solar panel. At one point the battery did run flat and I thought maybe it turned itself off so I disconnected it and reconnected the cables and still nothing. When change the setting I get an 'ff' flash after the setting has been selected. Not sure what this means as it is not in my one page instruction sheet I got with the controller.

Hi Zac. Just some ideas you could try:

If your batt is *really* flat, it may think it's in short-circuit and has shut down. Try a batt with at least some charge.

Disconnect the solar before connecting the batt so it can pick up '12V' itself. Then connect the solar. It may select '24V' otherwise.

Just a couple of things to try before despairing..

Hey John. Thanks for your quick reply. I have a dc-dc charging the aux matter so it is full again but still no response.

The green batt led means it knows it's fully charged. The sun led should start flashing when it gets some (looks dark there?). Just make sure it's set for 12V, not 24V.

Same problem for me guys. Any fix to this problem?

No more green lift flashing and I’m pretty sure it does not charge the battery...

However, surprisingly when I disconnect the battery + cable the green light is flashing normally. As soon as I reconnect it the array green light stops flashing...

I have no clue friends. If someone has a fix i’m really interested !

Cheers
