PV Substation

To reduce the overall cost of solar power plants and improve efficiency, CEEG introduces a complete photovoltaic substation composed of grid-connected inverters, transformers, high and low-voltage switchgear, and cabinets. This 50Hz 0.4-35KV three-phase AC PV system offers DC distribution, inversion, step-up, monitoring, and communication functions. It serves as a perfect alternative to the traditional "inverter room + step-up station," making it ideal for both distributed and centralized power generation.

Product Features

1. Turn-key Solution

All-in-one device integrating inverter, transformer, HV and LV switchgear. No on-site installation is required.

Container-type enclosure, easy to transport and load without the special lifting equipment.


2. Strong Environmental Adaptability

Anti-corrosion, high-strength steel enclosure.

Flame-proof with stable temperature functions and thermal insulation.

Excellent ventilation, sand, and dust-proof capabilities.


3. High Reliability and Safety

The cast-resin dry-type transformer inside the substation is fireproof, explosion-proof, and flame-resistant.

Certified C2, E2, and F1 testing standards.


Cost Reduction and Efficiency Improvement:

Lower investment and higher returns.

Saves 15% to 20% of total investment compared to traditional "inverter room + step-up station."

Reduces the number of foundations from two to one, saving 50% of installation time.

Copper connections between inverters and transformers eliminate the need for cables between the inverter room and the transformer. Structural optimization also reduces the requirement for two low-voltage switchgear units between the inverter and transformer.


4. Flexible Design: Can be customized according to customer site conditions.
