12-24v allpowers controller issue

[Juanitto]

Hi,

The display shows only the battery and the right black arrow! Although the panel is also linked, on the load output only the wires. The USB ports deliver, they are working.
Shouldn't appear all on the screen?

From your image the battery is indicating 14.4vDC. That would be full charge. I am not familiar with how your model SCC displays but it maybe it needs to be charging the battery for the solar icon to display.

I can not see from your image how you have it wired so can not comment if it looks correct.

Are you saying the panel is connected on the, right side, load terminals? Photo misses that detail.

Yes, all connected correctly (no load, the "load" is only on the usb, which are working), the load output has only the wires. The update would be that I thought to shake a bit the battery and now it appears the panel&sun&etc on the display and the battery half full....but still no load even I pressed the on/off button

...and after "shakin'" a bit the battery...and the usb provide 5v as shown with tester (the usb worked also before when appeard only the battery and no solar panel)

The solar panel connects on the left side. Under the solar panel symbol. What are the wires connected the load (right) side?

They are just wires connected there with that green connector. For now, I use only the USB outputs. It measures 4.85V, 1.7A, 7.8W (although they say 3A in the description).

Update: I added a load on the "load" wires, and then the "light bulb" appeared on the screen! Well, now the screen looks like it has to, but because I have a small battery (which serves more like a "resistance"), I set the menu at "load hours" at 00h (this means it should not discharge the battery after sunset, it's designed to choose how many hours after sunset will work the "load," from 00h to 24h) but well, I don't know why, in the daytime full sun, when I set 00h or 01h, the load output doesn't work! I had to set it like it comes "by default" at 24h. Is there an explanation for this?

Other issue is that I'm planning to add a proper battery to this setup.

I saw this :

Which for now I cannot buy it, but maybe would also work with something like this?!?:

What do you think about?

Being your first system, go with the lowest cost battery. Do not mix battery chemistry or sizes.
Also, The load terminals on your controller are only for a single, small load. Any larger loads should connect to the battery.

I didn't know this! So, for large loads (like what, for example?), should I also connect them directly to the battery? Currently, I have a small car charger with 2x5V2.5A@18W. Regarding the battery, I guess I need a 12V100Ah, which means 1200Wh. This means, for example, 10h@120W or 20h@60W, so I could theoretically run a 60W/h PC fulltime (and this should be connected directly to the battery as you said?)

Large loads like an inverter, for example.

The load terminals can be set to turn on /off lights and that, I believe, is the intended use for them.
