Connecting Watt Meter From Solar Panels To Charge Controller

If you have a pwm charge controller and plan to charge a 12v battery bank you must connect your panels in parallel.

Connecting watt meter from solar panels to charge controller. Generally speaking it is a good idea to obtain your solar panels before you buy a charge controller. As you see in the connection diagram at first the solar panel is connected to the solar charge controller and then a 24v battery is connected to the charge controller. The average 12 volt solar panel produces between 12 and 21 volts a level that would overcharge and damage a battery if transferred directly to it. To determine which set up is better we would answers to a few questions.

Solar charge controllers also known as solar regulators are an integral part of any stand alone solar system. In this video i show how to wire up a solar panel power meter in my vw t4 campervan conversion with links at the end for the items. To connect the rv solar system you would have to run a second set of cables from its charge controller directly to the terminals of the battery you want to charge. The white line is the negative connection all 3 panel negative wires are just simply tied together and to the wire that runs back to the negative connection on the charge controller.

This is why you can t connect your solar panel directly to your battery. An inverter is connected to the battery. The power meter is a chea. If you get a 20 amp charge controller you need to use a wire thickness that is able to carry 20 amps without overheating awg14 2 5mm or bigger.

The load terminal of the solar controller can be connected with a dc power device which is the same working voltage as the rated voltage of the battery and the controller supplies power to the load with the battery voltage connect the positive and negative poles of the load to the load terminals of the controller there may be voltage on the load side please be careful to avoid a short circuit when connecting the load a fuse should be connected to the positive or negative cord of the load. There is only a certain amount of data that a hard drive can store so you typically purchase a hard drive that is big enough for your needs. So the rv solar system now has two sets of cables one to its own battery and another set to the battery you want to charge. You will see a symbol that looks like a triangle pointing down at a horizontal line.

You can think of a charge controller in the same way that you would think of a hard drive on a computer. The red line is the positive connection to the panels. The output of the inverter is connected to ac loads like fans lights tv etc.
