Solar charge controllers are very easy to install. Most only require four connections. Two wires – positive and negative – run from the solar panel to the charge controller, and another two wires run from the charge controller to the battery bank. First, it’s important to make sure that you have a good connection between the two solar panels.
If the connection is not good, you won’t be able to charge your battery. Second, the charger should be connected to a wall outlet. Third, if you are using an inverter, be sure to connect it to an outlet that has the correct voltage and current rating for your system.

Do you need fuse between solar panel and charge controller?
For the most part, you do need a fuse between a solar panel and its charge controller as fuses and circuit breakers protect the wiring from getting too hot. Should a power surge occur, this will prevent appliances from catching fire or getting damaged.
If you are using an inverter, make sure you have the correct fuse or circuit breaker installed. If you don’t have one, check with your electrician to see if you can get one for free.
What happens if you connect solar panel directly to battery?
Even though the battery was fully charged, a solar panel will push current into it. The battery will eventually die if left connected. “It’s not like you can just plug it into a wall socket and charge it up,” .
Is a 20 amp controller enough for a 200 watt solar panel?
You’ll want to get a charge controller that can handle 15 amps or more if you’re using a 200w solar panel. The charge controller’s multiplier is around 1.25, so make sure you choose a device with the correct wattage.
What happens if a solar panel is not connected to anything?
It has a current that is not flowing. Solar cells are made of a material called silicon, which is a semiconductor. Silicon is the most abundant element on Earth, and it is used in everything from cell phones to computer chips. But it’s also the hardest material to work with, so it takes a lot of work to make a good solar cell.
In fact, silicon is so hard that it can’t be used for anything other than solar panels, because it doesn’t conduct electricity well enough to be useful as a conductor. The only way to use silicon in a cell is to heat it up and turn it into electricity. This process is called photovoltaic (PV), and the technology has been around for a long time.
Why is my solar panel not charging my battery?
Wrong solar panel setup, equipment problems, internal problems of battery or faulty battery, solar charge controller issues are the most likely culprits for your solar panel not charging your battery properly. Replacing the battery with a new one is the easiest way to fix them.
What size fuse do I need between solar panel and charge controller?
The wire set should be protected with a 60-amp fuse. The maximum capacity of the charge controller is also aligned with this. If you are using a battery charger, make sure that the battery is fully charged before plugging it into the wall outlet. If it is not, the charger may not be able to supply enough current to charge your battery.
