On the one hand, pulled by the local government's energy consumption policy, there is a huge market space and booming demand for the inverter air conditioner controller. On the other hand, enterprises are also required to face special circumstances and complex challenges. In India, there are three major challenges for the inverter air conditioner controller: wide voltage range, the product should be adaptable from 100 V to 300 V; high operating temperature, the highest operating temperature of similar products in China is 46℃, but in India, it may reach 50℃; large voltage fluctuation, after power failure, the highest instantaneous pulse voltage will reach 700 V, which is much likely to cause damage to electronic parts and components. In the face of such complex market circumstances and challenges, Topband team has been adhering to the mentality of "facing the difficulty" and completed the breakthrough. This is not only a breakthrough and innovation in past technology, but also a challenge to the physical strength and willpower of R&D personnel. The 55℃ high-temperature simulation laboratory was hard to bear. Each test lasted for two weeks, and a shift was needed to get some fresh air every half hour. After many times of selection and adjustment of parts and components, special processing of control algorithm and countless software adjustment, a low failure rate of the product in harsh environments was finally achieved. Topband became one of the first controller manufacturers to be BIS certified in India. Topband was not an early entrant to the air conditioner controller market in India, but with its best adaptable products and customer service spirit to solve problems at any time, Topband ranks first among the latecomers in this land, and is well received by customers. Being acute and resourceful promotes the innovation of bidirectional inverter In recent years, the market of bidirectional inverters has rapidly expanded from the field of battery formation and capacity grading to portable and household energy storage. Topband team is keenly aware of the development trend of the product, and thus concentrates on making technical breakthroughs in advance. It is just a change in the application scenario, though, a great challenge is yet brought to the technology of bidirectional inverter.
