A solar step-up transformer is a low loss power transformer suitable for solar power generation. 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
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.
