"solar panel- gives volts but no amps" için yanıtThere would be no current if the battery was fully charged. Connect it to a known load of about the specified wattage; a car headlamp bulb is best........... if you're doing it without a regulator, I'd recommend a truck bulb (24volts). Even with the panel oriented for maximum performance, the maximum current should be about 1.7 amps (32/18.8) in the winter in England. I'd guess you're getting about 1 to 1.2 amps based on my experience. This is a same phenomena with work truck power inverter So, 1.2 amps multiplied by 18.8 volts equals 22.5 watts. A bulb with a voltage of 24 volts and a power of about 25 watts will be suitable. Connect this in line with the ammeter (10 amp range) throughout the panel output.
