Weather conditions are n't something people can control. We like to think that we're capable of predicting them correctly; but let's face it, a lot of the time we ’re wrong. And this means solar energy is somewhat unreliable as well.

You see solar energy might be an excellent renewable resource, but the power provided by the sun can vary tremendously based on several factors: location, time of day, season, etc. As a result, there will be periods when your solar panels can't gather enough energy to charge your solar battery effectively.

And there will be other times where the sun's bright, away from clouds, and capable of providing a surge of energy that makes your solar panels work at their peak performance. Both of these scenarios create an amount of energy that can cause damage to your solar battery.

#Add a little knowledge about solar panel, we normally charge 12V battery solar panel output maximum working point voltage is about 18V, 24V battery charging solar panel output maximum working point voltage is about 36V, the output voltage of solar panel is greater than the battery voltage, so the controller is a necessary hardware device to protect the battery from overcharging.

For instance, a total lack of solar energy might lead to an extremely low discharge that reduces your battery 's lifespan. Meanwhile, an excessive amount of power could lead to your battery overheating, which could also reduce its lifespan.

These outcomes are n't something anybody using solar panels wants. And it's why you need a solar charge controller. This device will sit between your battery and solar panels to control the energy your battery receives.

Therefore, it'll ensure your battery does n't overheat or have such a low discharge rate that it ends up causing damage. Overall, it'll make sure your Boat / RV's solar energy system runs efficiently for years to come.
