China Solar Step-Up Low Loss Power Transformer Suppliers - High Efficiency Factory Equipment for Indoor/Outdoor Use
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

Frequently Asked Questions
Q1: What is the primary role of a solar step-up transformer?
It is designed to increase the voltage produced by solar inverters to a higher level suitable for the electrical grid, compensating for the discontinuous nature of sunlight.
Q2: Can these transformers be installed in extreme weather conditions?
Yes, they are designed for both indoor and outdoor use, withstanding temperatures from -30℃ to +40℃ and wind speeds up to 35M/s.
Q3: What package solutions are available for solar projects?
We offer flexible designs including containerized AC Stations, L-H Combo & Inverter Packages for large capacity, and standalone Inverter Packages.
Q4: Is there an altitude limit for the installation of these transformers?
The standard maximum installation altitude is 2000 meters above sea level. For higher altitudes, please consult our technical department.
Q5: What quality tests do the transformers undergo?
Every unit undergoes rigorous testing including voltage ratio, resistance, no-load/load losses, impulse voltage withstand, noise levels, and oil leakage tests.
Q6: How does the transformer handle overloads?
The transformer is tested to handle an overload of 150% rated current for one hour following the temperature rise test.
