Introduction: Photovoltaic lights up the countryside, technology empowers the future
Under the dual promotion of "dual carbon" goal and rural revitalization strategy, distributed photovoltaic power generation is becoming the core path of new rural power supply transformation. However, the rural power grid environment is complex, the equipment operating conditions are harsh, how to ensure the efficiency, safety and stability of the photovoltaic system has become a key issue to be solved. With its deep technical accumulation in the field of current sensors, CHIPSENSE uses multiple series of high-precision products as the fulcrum to inject "wisdom core" into the transformation of photovoltaic power supply in new rural areas.
1. Accurate monitoring: from "extensive power generation" to "lean management"
Traditional rural photovoltaic system is often due to the lack of current monitoring accuracy, resulting in low power generation efficiency and difficult troubleshooting. Through high-precision Hall and fluxgate technology, CHIPSENSE current sensor realizes full-link accurate monitoring from power generation, energy storage to grid-connection.
Power generation: In the PV series branch, CHIPSENSE AN3V PB51 open-loop sensor can monitor the current output of each PV panel in real time, covering a range of 10~120A, with an accuracy of up to 0.5%, helping to quickly locate abnormal components and reduce power generation loss.
Inverter: The CR1V PB04 closed-loop current sensor supports wide temperature operation between 40 ° C and 150 ° C, accurately captures the current signal of DC input and AC output, provides data support for the inverter maximum power point tracking (MPPT), and improves the system conversion efficiency by more than 10%.
Energy storage management: In response to the frequent fluctuation of electricity demand in rural areas, the AS1V series sensor monitors the charging and discharging current of energy storage batteries in real time with an extreme error rate of ±0.1%, ensuring smarter and more economical energy scheduling.
2. Safety escort: from "passive protection" to "active early warning"
Rural photovoltaic equipment is often faced with leakage, overload and other security risks, through the fluxgate technology and intelligent diagnosis algorithm, to build multiple security lines.
Leakage protection: FR2V H04 and FR6V H00 series sensors can detect DC leakage current as low as 0.01A, with millisecond response mechanism, automatically cut off the fault circuit in humid, high temperature and other harsh environments to avoid the risk of electric shock.
Overcurrent protection: The HS2V H00 sensor deployed in the bus box, with a measuring range of 1500A, can monitor the total output current in real time. Once a short circuit or overload is detected, the protection mechanism is triggered immediately to prevent equipment damage.
Insulation guarantee: The whole series of products have passed UL 94V0 certification, and the original electrical isolation design of the secondary side can still operate stidly even in the rural power grid where lightning strikes and electromagnetic interference are frequent.
3. Cost reduction and efficiency increase: from "import dependence" to "domestic substitution"
In the past, rural photovoltaic projects were limited in promotion due to the high cost of imported sensors. CHIPSENSE achieves the same or even better performance at a lower cost through a breakthrough in localization technology.
Cost advantage: The use of open-loop hall design, support 100℃ high temperature environment, the price is only 60% of imported products, greatly reducing the cost of rural photovoltaic system construction.
Flexible adaptation: CHIPSENSE sensor covers the full range of 5mA~5000A, supports customized development, and can seamlessly connect different brands of photovoltaic modules and energy storage equipment, reducing the compatibility problem of transformation.
Convenient operation and maintenance: For example, CS1V PB00 series adopts modular design, installation and maintenance without professional tools, ordinary electricians can operate, significantly reducing later operation and maintenance costs.
4. Wisdom Integration: From "single point application" to "system interconnection"
New rural photovoltaic transformation not only needs hardware support, but also needs deep integration with digital management. CHIPSENSE promotes intelligent rural energy management through sensor + iot solution.
Remote monitoring: Sensor data can be uploaded to the cloud platform in real time, and farmers can view power generation, energy storage status and fault warning through their mobile phones to achieve "unattended" management.
Energy efficiency optimization: Combined with historical current data, the system automatically analyzes photovoltaic array efficiency decay trends and recommends cleaning or maintenance cycles to extend equipment life.
Grid coordination: In grid-connected scenarios, FT2V H00 sensors accurately monitor the DC component injected into the grid to ensure compliance with national standards and avoid fines and network outage risks.
Conclusion: Technology to the countryside, green electricity to promote agriculture
With "precision, safety, cost and intelligence" as its core competitiveness, CHIPSENSE current sensors are gradually becoming the "invisible guardian" of new rural photovoltaic transformation. In the future, with the deep combination of rural revitalization and energy transformation, CHIPSENSE will continue to use technological innovation as a plow, deep cultivation of green fields, so that every ray of sunshine can be transformed into the surging momentum of rural revitalization.
