Buying Guide for the Best Solar Controllers

Why should you purchase a solar controller?

Do you use solar panels for generating electricity and for running your electronics at home or in the office? Have you ever wondered what would happen with your appliances on a severely hot, sunny day in this case? Well, the excess sunlight can overheat the solar batteries, and this may cause damage. To prevent this from happening, you need solar controllers. The best solar controllers would ensure that appropriate amount of electric power gets distributed to and from the solar batteries that power the various appliances in your home or office.

Important Features

What are the things you should consider when buying a solar controller?

After going through thousands of solar controller reviews, we have summarized what you should consider when buying one for your home or office:

  • Check the basic requirements: Solar controllers are available in different sizes and shapes. In order to find the one most appropriate for your home or office, you will first need to identify the voltage and current generated from your solar battery. Then check out the two types of solar controllers: the Pulse-Width Modulation (PWM) controllers, and the Maximum Power Point Tracking (MPPT) controllers. Identifying the features of both these types will help you decide which one is suitable for your needs.

    • PWM controller specifications: The PWM solar controller adjusts the charging rate depending upon the level of the battery that you are using. This helps charge the battery to the optimum level. The strong point of these solar controllers is their durability—they can be used for years and are rather competitively priced. They are available in sizes up to 60 Amps.

    • MPPT controller specifications: The MPPT solar controller costs more than the PWM controller, but it will work in a way so as to capture the maximum power from solar panels or cells. Since it can absorb a much higher amount of power, this type of solar controller is considered to be more efficient than PWM controllers. It has the capacity to retain a higher input voltage before converting it into electrical power.
