The 10 Best Solar Charge Controllers of 2021

A charge controller system is necessary to prevent damage to the battery. It falls between both the energy generation source, the solar panels, the energy storage portion (battery), and the final charge—ensuring accurate and complete management of energy flows and device safety.

Did you know that you can destroy your battery’s life span by simply charging them with solar panels? If it is not carefully controlled, solar power will cause the batteries to charge beyond full capacity. Light from the sun allows the batteries to overcharge which causes all kinds of problems. A solar charge controller is used to address this problem. It is a vital system that helps control the voltage from the solar panels and protects the batteries from being overcharged.

Solar charge controllers that are attached to high-amp solar panels and batteries provide a wide variety of power outputs. This tells us they can pay for different types of batteries. Charge controllers with high power output have a 60-amp output. Such machines can be used to charge 12V batteries to 48V batteries. Less efficient charge controllers, such as those with 20-Amp power out, are used to power 12V and 24V batteries.

Budget

Are you having a budget-constrained? Your energy needs are limited? Then you need to go to the most effective and affordable solar charge controller. The solar charge control system would usually be the perfect solution for small solar systems to secure and securely charge your battery. Now, if you want to get the most power out of your PV array, an MPPT controller may be your solution. Usually, they can recharge a battery-based device with lighting, cooking, and heating devices as they are equipped to meet higher energy requirements.

Protection features

Safety features are a must when it comes to charging controllers. Literally put, the more functionalities you have, the greater. The charge controller should have features such as a reversible safety mechanism. This helps you to charge backward. And it has to have other security features, such as protection devices, discharge protection, and short-circuit coverage. Look for a Solar Charge Controller analysis of the product you want to better understand its effectiveness.
