SolarSolarOneV3 loading with solarpanel?

Hello,

i have the problem that the battery not load with solarpanel.
I have a 3,7 V battery, the Solarpanel is 5.5V 100mA.

If I hold the panel to the sun, then I measure only 50uA charge current.
The little yellow light flickers only briefly, then no longer.

What is the problem ?

Thanks for help

Hi @Philipp_Luond,

When the battery is already fully charged the battery won’t charge and the charge LED will go off.

It depends on the weather conditions how much current the solar panel will produce.
If the panel is hot, it will produce less. If there are clouds there will be less.
50 uA is very little, I hope the reason is that the battery is fully charged.

Best regards,
Jan

Hello,
the battery is on 3.3V also not full. Is posible the on the Hardware is somthing defect ?

Thanks

Hi @Philipp_Luond,

You can measure the current when you apply 5V with a power supply on the solar input to see if the solar panel is faulty.

Hi,

Good that the new one does not have this issue.
Please contact the webshop to swap the broken board for a new board.
I will also send a message to them.
