Is a 12W solar panel good for a deep cycle battery?

A 12W panel / cc to a deep cycle battery is more of a maintainer, and not a top-off really. Especially if your panel is horizontal on the boat, and your solar-insolation is poor in the marina.

Why is there no battery voltage on the controller?

Th ebattery is the ver first thing to be terminated to the controller, then the panels are last. So if you do not see battery voltage on the output of the controller you have a wiring error. If it was wired correctly in the proper order to start with, you would have had a voltage on the output of the controller period.

How do I know if my solar panel is charging a battery?

You can check if your solar panel is charging a battery by using a multimeter. Connect the probes to the positive and negative wires from the solar panel and set the multimeter to the direct current voltage setting. If the multimeter shows a reading around 12-20v during peak sunlight times, the solar panel is working and charging the battery.

How do you measure a solar panel voltage?

The open-circuit voltage is the maximum voltage that the solar panel can produce. To measure this: Set your multimeter to Direct Current (DC) Voltage. Connect the red lead from the meter to the positive terminal of the panel, and the black lead to the negative terminal. The reading should be close to or above the panel's rated voltage.

How to test a solar panel?

Check the voltage and the amperes of the solar panel. Observe if the weather conditions are suitable for testing. Once you are done, you should set the multimeter in terms of DC voltage and DC amperage. Set the multimeter in terms of DC voltage to test for voltage. Ensure you set the maximum voltage to accommodate the voltage readings.
