How many amps does the bc-5w pro generate?

Max 0.27Amps for 5W; 0.56amps for 10w and 0.67amps for 12w

I plan on connecting this to our tractor full time. Can i still drive it without disconnecting it?

Absolutely! Mine stays connected to my truck battery all the time and it works great! I live on an island and there are gaps between driving so this keeps my battery charged and ready when I get back to the island. I liked it so much I bought one for each of my vehicles.

Does this require a battery tender. I have a couple other solar charger which must have a tender to prevent overcharging

Unlike other regular solar charger, the solar charger was built-in intelligent mppt charge controller chip to prevent over charge, over voltage, short circuit, no addtional battery tender is required.

The indicator light turned off and and it is almost dark. Does this mean

The LED indicator is powered by sunlight, it will not come on if sunlight is not sufficient. Expose the solar panel to full sun, see if the light comes on? If not, pls get back to our support team thru email support@sunerpower.com
