SCCM10-100 Assistance

Postby Claire Rose on Mon Nov 13, 2017 9:11 am

I'm likely in the wrong subject matter section but I couldn't find a closer match on topics and the search of forums and support turned up nothing.

I just completed an installation of a SCCM10-100 MPPT Charge Controller with 100 watt panel and 80ah battery. The load is LEDs - above the .25 amp load requirement.

The controller seems to charge the battery and the indicator lights seem to be working. The problem is that it shuts down after dark; almost as though the battery is low. The battery is fully charged and shows over 13 volts.

The Load works fine so long as the PV panel is getting light and continues to function at dusk for a while before the whole thing turns off.

Is there a dip switch someplace to use the panel as a dusk to dawn shut off? Or is this just a defective unit? This is a new unit even though it is manufacture discontinued.

Thank you for the assistance.

What are the LEDs doing after dark?

Do you have the battery sensing wire connected from the battery positive terminal to terminal 7 of your inverter? This wire is separate from the main battery connection to terminal 3 (edited - had wrong #).

Just looking at the manual, that's all I can suggest.

The LEDs on the controller go off after dark.

Yes, I have a voltage sensing wire connected as well as a temperature sensor.

Thank you.

I may try not using the load terminals and just connect to the battery. I won't have the low battery shut off but at least I can get some light after dark.
