In China, distributed photovoltaic power generation is booming. In March 2025, as many as 4,352 new industrial and commercial distributed power generation projects were newly established across the country.
According to the "Notice on Deepening the Market-oriented Reform of New Energy Feed-in Tariffs and Promoting the High-quality Development of New Energy" jointly issued by the National Development and Reform Commission and the National Energy Administration, if these projects can be connected to the grid before May 31, 2025, they can continue to implement guaranteed the electricity prices (such as 0.35 rmb/kWh for centralized photovoltaics). If they fail to catch up, they will enter the market at the market price (currently about 0.3 rmb/kWh), which is 14% lower than the original guaranteed electricity price. It marks a new era of the distributed photovoltaics officially are moving from "policy-driven" to "market-driven". CHIPSENSE will be one of them.

1.CHIPSENSE CM5A series Current Sensor: Precision Measurement for Cost Reduction and Efficiency Improvement

CM5A series is a high precision Hall effect-based current sensor independently developed by CHIPSENSE, which can accurately measure the current during the charging and discharging of energy storage batteries with extremely low error rate, providing a strong guarantee for the stable operation of distributed photovoltaic systems, optimizing system performance and reducing operation and maintenance costs.

Technical Highlights:

Electrical isolation design: CHIPSENSE insulation design is adopted between the primary and secondary sides of the sensor, which effectively avoids the influence of electrical interference on the measurement results and ensures the safe and stable operation of the system.
Wide temperature range working ability: Under the complex and changeable climate conditions in South China, the wide temperature range working ability of CHIPSENSE CM5A series current sensor is particularly important, ensuring the reliable operation of the system.
Modular design: CHIPSENSE offer customer to customize, conducive to system integration, and can be easily integrated with other equipment or systems. At the same time, it can also reduce costs and facilitate domestic substitution.

2."Optical storage and charging" integrated solution: earn 30% more electricity bills

In distributed photovoltaic projects, the configuration of energy storage systems has become the best key to improving the economics of the project. By integrating CHIPSENSE CM5A series current sensors, combined with advanced energy storage technology and intelligent charging management system, distributed photovoltaic projects can realize an integrated solution of "optical storage and charging". This solution can not only effectively balance the fluctuation of power generation and increase the proportion of spontaneous self-use, but also maximize the income of electricity bills through the difference between peak and valley electricity prices.

Actual Case:

An industrial and commercial distributed photovoltaic project has installed CM5A series current sensor from CHIPSENSE, and is equipped with an efficient energy storage system and an intelligent charging management system. By accurately they measuring the charging and discharging current of the energy storage battery, the system can adjust the charging and discharging strategy in real time, making full use of the difference in peak and valley electricity prices. CHIPSENSE is estimated that in the first full operation cycle after the project is connected to the grid, through the integrated solution of "optical storage and charging", the electricity revenue has increased by nearly 30% compared with the traditional model.

3.Current sensor selection and domestic substitution

In the process of current sensor selection, CHIPSENSE CM5A series current sensor have become the first choice of many investors due to their excellent performance and cost performance. At the same time, as a leader in domestic alternative current sensors, it also provides the market with high-quality same industry company alternatives, breaking the monopoly position of foreign brands in the high-end current sensor market.

Brand strength:

As a leader among current sensor manufacturers, CHIPSENSE has continuously introduced innovative products to meet the diverse needs of the market with its deep R & D strength and rich industry experience. Its brand influence is expanding day by day, becoming a current sensor brand trusted by many investors.
In the future, with the continuous improvement of the power cash market and the continuous advancement of energy storage technology, distributed photovoltaic projects will pay more attention to economic benefits and technological innovation. CHIPSENSE will keep integrate advanced current sensor technology and intelligent management systems, distributed photovoltaic projects will achieve more efficient and reliable operation, contributing to the construction of new power systems and the promotion of energy transformation.

CHIPSENSE is a national high-tech enterprise that focuses on the research and development, production, and application of high-end current and voltage sensors, as well as forward research on sensor chips and cutting-edge sensor technologies. CHIPSENSE is committed to providing customers with independently developed sensors, as well as diversified customized products and solutions.
