Photovoltaic Solar Capacitor

Core Advantage

Efficient and stable wave suppression, protecting the core: The Photovoltaic Solar Capacitor supplied by Piner Electronic manufacturer is produced using an inductive winding process. It effectively absorbs the ripple current generated by the photovoltaic system, significantly reducing the fluctuation of the DC bus voltage, protecting the core power components of the inverter and lowering the failure rate.

Wide voltage and high current, fully compatible across all scenarios: Supports DC voltages ranging from 450V to 3000V, capable of withstanding continuous currents of 20A to 200A and instantaneous surges that are twice as high. It fully meets the requirements of household, commercial and industrial, as well as power station-level photovoltaic inverters.

Improve system efficiency and boost power generation: Quick response, reduce bus voltage drop, help increase the overall conversion efficiency of the photovoltaic system by 0.5% - 2%, achieve optimized power generation.

High temperature resistance, long lifespan, maintenance-free: Utilizing fully industrial-grade high-temperature-resistant materials and structural design, it can adapt to outdoor high-temperature environments, has a long service life, and significantly reduces the operation and maintenance costs of power stations.

Safe explosion-proof, reliable flame retardant: With an internal explosion-proof design and an advanced flame-retardant casing, it effectively eliminates the risks of explosion and fire, ensuring the electrical safety within the photovoltaic DC cabinet.

Modular design, supporting high-power systems: The high-power models can adopt a parallel integration structure, with stronger current carrying capacity. It is specially designed for megawatt-level equipment such as centralized inverters and energy storage converters.

Full outdoor protection, strong environmental adaptability: Solid structure, no risk of liquid leakage, featuring moisture-proof, shock-resistant, corrosion-resistant and other properties, capable of easily coping with the complex outdoor environment of photovoltaic power stations.

Stable voltage regulation, adaptable to photovoltaic power generation characteristics: It can quickly respond to voltage fluctuations caused by changes in light intensity, maintain the stability of the DC side voltage, and enhance the reliability of system operation.

Typical application scenarios

Photovoltaic Solar Capacitor is suitable for household/industrial commercial string-type photovoltaic inverters, centralized photovoltaic inverters, photovoltaic combiner boxes, DC distribution cabinets, photovoltaic energy storage converters (PCS), distributed and ground photovoltaic power stations and other systems.
