High-Efficiency China Solar Step-Up Low Loss Power Transformer - Leading Suppliers & Factory Solutions
Farady A solar step-up transformer is a low loss power transformer suitable for solar power generation.
General
It is used to step up the voltage as produced by the solar inverters. The output power of photovoltaic power generation system with discontinuous sunlight intensity and duration makes it necessary to use a step-up transformer to increase the voltage level of the generated electricity.
Standard Features
- Flexible designs that include the following package solutions:
- AC Station: Comprised of PV inverter, transformer and switchgear. All containerized.
- L-H Combo & Inverter Package: Comprised of multiple PV inverters and switchgears to attain large capacity output.
- Inverter Package: Containerized inverter-only solution for those who wish to procure transformers and switchgears separately.
- Minimizes construction and installation time and overall cost.
- Protection from harsh environments.

Frequently Asked Questions
What is the main function of a Farady solar step-up transformer?
It is specifically designed to increase the voltage produced by solar inverters to a higher level suitable for the power grid, compensating for the discontinuous nature of photovoltaic power generation.
Can these transformers withstand harsh outdoor environments?
Yes, they are designed for both indoor and outdoor applications with protection against harsh environments, including wind speeds up to 35M/s and temperatures ranging from -30℃ to +40℃.
What flexible package solutions are available?
Farady offers three main solutions: the AC Station (all-in-one containerized), the L-H Combo & Inverter Package for large capacity, and a containerized Inverter-only Package.
What are the standard altitude and humidity limits for installation?
The standard maximum installation altitude is 2000 meters above sea level. The unit handles a monthly average humidity of 95% and a daily average of 90%.
What routine tests are performed to ensure quality?
Comprehensive tests include voltage ratio, winding resistance, no-load/load losses, impedance voltage, impulse voltage withstand, noise level, and oil leakage tests.
Is it possible to use the transformer beyond standard service conditions?
Yes, for conditions exceeding the standard parameters (such as higher altitudes or extreme pollution), you should consult the manufacturer's technical department during the ordering process.
