Product descriptions from the supplier
Product Overview：
Photovoltaic isolation transformers use low-loss materials and have the characteristics of high output conversion efficiency. The product has a high load capacity, anti-interference, fireproof, moisture-proof, safe and reliable, power-saving and convenient maintenance, etc., and plays the role of isolated power supply in photoelectric conversion, and can work normally for a long time in outdoor high-temperature environment. Solar energy has attracted more and more attention due to its advantages of no pollution, no noise and wide distribution. At present, most of the photovoltaic grid-connected power generation systems contain isolation transformers, and there is a leakage current problem in photovoltaic power generation systems without isolation transformers.
Product features：
Electrical isolation: The transformer is used to realize the electrical isolation between the photovoltaic power supply and the power grid.
Prevent the DC component of the current from being injected into the grid: Since the DC power does not cause a change in the magnetic flux, the DC component of the PV inverter system will not flow into the grid through the isolation transformer.
Anti-interference effect: the isolation transformer with a certain connection mode can eliminate the integer multiple harmonics of the 3rd and 3rd, and reduce the impact of higher harmonics and voltage fluctuations on the power grid.
The role of stable voltage: when the system fails, it can effectively suppress the resonant overvoltage and steady-state overvoltage of the photovoltaic inverter system.
Technical data：
Outdoor Large-Scale PV Power Plant Grid-Connection：Suitable for outdoor high-temperature/dusty environments such as deserts and plateaus. The 304 stainless steel enclosure resists corrosion, and the combination of high conversion efficiency and power isolation function prevents leakage current, ensuring grid-connection safety.
Industrial and Commercial Distributed PV Projects：Used for rooftop PV arrays of factories and commercial buildings. The DC component injection prevention function protects power grid quality, and the anti-interference feature eliminates 3rd and multiple harmonics, reducing interference to production/electrical equipment.
Coastal/High-Salt-Fog Area PV Systems：Targeting coastal and island projects. 304 stainless steel resists salt-fog corrosion; combined with fireproof and moisture-proof properties, it adapts to humid and rainy climates, ensuring stable power generation.
Special PV Scenarios with High Reliability Requirements：Applicable to PV + energy storage microgrids and backup power for hospitals/data centers. The voltage stabilization function suppresses fault overvoltage, and electrical isolation prevents grid interference, ensuring the safety of critical loads.

Why Must a Transformer Core Be Grounded at Only One Point? Isn't Multi-Point Grounding More Reliable?Why Does the Transformer Core Need to Be Grounded?During operation, the transformer core, along with the metal structures, parts, and components that fix the core and windings, are all situated in a strong electric field. Under the influence of this electric field, they acquire a relatively high potential with respect to ground. If the core is not grounded, a potential difference will exist between the core and the grounded clamping structures and tank, which may lead to intermittent discharge.I01/29/2026 -
