Factors To Be Considered Before Buying The Best Solar Charge Controllers In India

1. Types Of Solar Charge Controllers:

The first most important factor that you must have some knowledge about before buying the best solar charge controller in India is the types of controllers available. 

  • PWM Solar Charge Controller- This type of solar charge controller aims at matching the solar panel voltage to the voltage of the battery. In doing so, it reduces the panel’s output voltage. 
  • MPPT Solar Charge Controller- This is an electronic DC to DC converter that optimizes the matching voltage between the solar panels and the battery. The higher voltage DC is converted to low voltage to power the battery bank. The excess voltage from the panel is converted to electricity for the house or office. 

2. Maximum Current:

You must check the maximum current rating of the solar charge controller before making a purchase. It tells a lot about the performance of the controller as well as its capability of handling high-load appliances. It indicates the maximum current that the device can deal with. Basic budget models can usually handle 10 or 20 amps of current, whereas the more high-end ones can handle 30 to 40 amps. 

3. Voltage Rating:

This is another crucial factor that you need to consider. The voltage rating does not affect the performance of the controller in any way but it ensures versatility and compatibility levels of the device. Almost all the solar charge controllers mentioned in this article are compatible with both 12-volt and 24-volt solar panel systems. 

4. Warranty:

Once installed, solar panels tend to last for decades. However, this is beneficial only when the other parts of the solar panel are just as reliable. To ensure that the solar system functions for a long time, check for the warranty offered by the solar charge controller company. Most of these devices come with a 1-year warranty but a few better ones have a 2-year warranty on them. 

Frequently Asked Questions

MPPT solar charge controllers have a higher power output compared to the PWM solar charge controllers. It can harvest an additional 11.1% of energy. Thus, MPPT is better than PWM. 

2. What capacity solar charge controller do I need?

This depends on the amount of energy that your solar panels produce. You require a solar charge controller that can handle this load efficiently. Thus, if the panels produce 480 watts of energy then you require a 20 amps solar charge controller. Typically, the amperage rating of controllers ranges from 1 to 60 amps. 

3. How many watts can a 20 amp solar charge controller handle?

A 20 amps solar charge controller can handle approximately 480 watts. 

4. What is the function of a solar charge controller?

A solar charge controller is essentially a protective guard that limits electrical energy flow from the solar panels to the battery. It prevents overcharging as well as undercharging. It also protects against excessive voltage flow. 

Conclusion

Solar charge controllers are a boon for all solar panel users because of the crucial protection to the solar battery. A lot of damage is possible without the controller regulating the flow of energy from the solar panels.
