The market of the Solar Charge Controllers have been rapidly increasing every year, the website Fortune Business Insights created a detailed study about this topic, just as a reference, it reported that the market size of Solar Charge Controllers just in North America is 0.39 billion dollar. But the market of solar charge controllers is divided in two different technologies: pulse width modulation (PWM) and maximum power point tracking (MPPT).

According to Fortune Business Insights “Currently, the MPPT charge controller segment accounts for a lesser share in the market than the PWM charge controller due to the difference in the price of the two. But, the operational advantages such as better efficiency in low sunlight, long wire ruins, and low battery charge would cater to the rising share of maximum PowerPoint tracking (MPPT) charge controller during the given forecast period.”

Looking at the report, it is possible to conclude that innovations in the technologies of MPPTs can have a great impact in the market, which is massively conquered by PWM chargers due to price. A reduction in the cost of MPPT chargers can create a significant impact in a market that has the size of 0.39 billions just in North America, while also providing great benefits for the consumers because of the increased efficiency of the technology.

Targeted Specifications for Better Adaptability

Similar to any new development, it is always important to consider the point of view of the consumer. For that we will evaluate two types of consumers:

• The consumer that is building a new PV system and is also interested in using the MPPT technology, will compare different alternatives and the proposed device can potentially stand out because of the increased efficiency provided by the extra MPPT inputs.
• The consumer that already owns a PV system and is looking to replace the PWM or the MPPT controller will be interested in the increased efficiency but also will need the new technology to be as compatible as possible to the already implemented system.

With those thoughts in mind, the proposed solution should be compatible with the most common specifications of batteries, solar panels and inverters. Looking at the best selling energy controllers in Amazon we can se typical specifications for an MPPT system, the list updates constantly so it might not be the best reference, we could also look at the article “Best MPPT Solar Charge Controllers: 12 Best MPPT Solar Charge Controllers for Off-Grid Power” from Off Grid Power Boom to obtain some references.

After comparing with other alternatives the following target specifications are proposed for the design:

• 48V or higher voltage input
• 10A or higher output current
• 12V/24V output voltage
