A photovoltaic generation system is a power generation system that converts solar energy directly into electricity using solar cells based on the photovoltaic effect. Depending on the transmission method, photovoltaic systems can be classified into three types: standalone, grid-connected, and distributed systems. These systems are praised for their safety, reliability, noise-free operation, pollution-free nature, and flexibility in resource distribution, making them highly favored by various countries and industries with vast development potential.
Working principle: Photovoltaic modules convert solar energy into DC power. After AC/DC conversion by the inverter, the AC power is then fed into the grid via a step-up station.
Jiangsu Ningyi currently offers photovoltaic power generation box-type substations and integrated inverter-voltage booster box-type substations, designed to address functions such as current collection, current conversion, and voltage boosting in photovoltaic power generation. These products feature easy installation, high integration, compact footprint, advanced intelligence, remote monitoring capability, and convenient operation and maintenance.

Solar power generation requires equipment that can handle fluctuating loads and harmonics. Our transformers (both Dry-type and Oil-immersed) are specifically designed for low no-load losses and high operational efficiency. By reducing internal power consumption, our solutions maximize the effective power output fed into the grid, ensuring a higher Return on Investment (ROI) for solar farm operators.
Photovoltaic plants are often located in challenging environments, from high-temperature deserts to humid coastal areas. Our box-type substations feature industrial-grade enclosures with high IP ratings (dust and water resistance). Our special anti-corrosion treatments and advanced heat dissipation designs ensure stable operation and a long lifespan, even under extreme weather conditions.
We don't just supply components; we provide complete systems. Our integrated inverter-voltage booster substations combine LV distribution, transformers, and HV switchgear into a single, pre-fabricated unit. This highly integrated design reduces on-site wiring work, shortens the project construction cycle, and minimizes land occupation, offering a true plug-and-play experience for EPC contractors.
We adhere to strict international manufacturing standards (IEC/IEEE). Every unit undergoes comprehensive testing—including temperature rise, lightning impulse, and short-circuit withstand tests—before leaving our factory.This rigorous quality assurance guarantees that Jiangsu Ningyi equipment operates reliably for decades, safeguarding your solar assets.
