Our Story about This Solar Charge Controller :CMP12 Series Version History
In a company renowned for innovation and challenges, there was a product series named CMP12. The story of CMP12 began with Version 1, where engineers meticulously crafted an engineering prototype and sent it to European customers for testing. After rigorous testing and trial orders, CMP12 passed all evaluations with flying colors, marking the beginning of its market journey.
As market demands evolved and technology advanced, the team quickly launched Version 2, improving the protection circuitry to ensure stability and safety, thus initiating mass production. Soon after, CMP12 reached a significant milestone with Version 3, which introduced 6V voltage adaptability, becoming the first in the industry to offer this feature and expanding its usability across various scenarios.
With increasing demand in overseas markets, Version 4 emerged to meet international order requirements through large-scale production. Following closely, Version 5 not only expanded its presence in overseas markets but also pioneered the use of Surface-Mount Technology (SMT), enhancing production efficiency and product quality.
To further improve performance, Version 6 optimized circuit design, boosting overall efficiency and upgrading three key component groups, significantly increasing throughput. Then came a major breakthrough with Version 7, which added communication functionality, making it the only product in the industry with this feature, and introduced new heat dissipation methods, further enhancing reliability and stability.
In Version 8, CMP12 achieved communication self-check capabilities, and the new cooling technology demonstrated exceptional heat dissipation performance, ensuring efficient operation even in extreme heat environments. Version 9 focused on optimizing voltage switching circuits, making voltage transitions smoother and more efficient.
Today, the CMP12 series has evolved to Version 10. Though the story continues, “We are continuously striving…,” every new version embodies the dedication and ingenuity of the team. Each improvement aims to provide users with a better experience. CMP12 is not just a product; it symbolizes technological innovation and relentless pursuit, inspiring the team to keep moving forward and embrace every challenge that lies ahead.
