Product Overview
Step-Up Grid-Connection Prefabricated Cabin
Step-up grid-connection prefabricated cabins are used in energy storage and power generation systems to connect solar, wind and battery units to the utility grid. The cabin integrates an incoming-line compartment, a step-up transformer compartment and a grid-connection compartment in one containerized module, reducing on-site installation work and shortening project commissioning time.
The grid-connection control system is equipped with anti-islanding protection to ensure safe and reliable disconnection from the grid when required. The container-type enclosure provides high structural strength and IP55 protection, with factory assembly and commissioning completed before shipment.
We configure the transformer rating, protection scheme, metering and grid interface according to the project grid code and utility requirement. Each cabin is supplied with drawings, test records, export packaging and commissioning support.
Before production, our engineers review the project single line diagram, protection scheme, metering requirements, cable entry and local grid standard. After approval, we complete factory assembly, routine testing, export packaging and documentation, and provide commissioning and after-sales support after delivery.
