1. Communication protocols for external communication can be customized to meet individual project requirements, as these can vary significantly from site to site. Common communication protocols include Modbus-RTU, Modbus-TCP, CAN2.0B, IEC61850, IEC60870-5-104, and IEC60870-5-103.

2. Each PCS (Power Conversion System) manufacturer has unique interface locations and types, necessitating the design of a tailored structure for each PCS manufacturer.

3. The AC measurement voltage level for PCS can range from 0.315kV to 0.69kV. Typically, for PCS AC measurement voltages at or below 0.4kV, the corresponding DC side rated voltage does not exceed DC1000V, and such models are predominantly intended for indoor use. For PCS AC measurement voltages between 0.5kV and 0.69kV, the corresponding DC side rated voltage is generally DC1500V, and these models are designed for outdoor use, often achieving IP54 or higher protection levels.

4. The ESVB-CU enclosure can be either a container-type enclosure, often custom-sized and fully welded, which tends to be relatively expensive, or a standard assembly-type enclosure, offering cost savings. In most cases, the latter option is recommended for clients.

Currently, energy storage transformer capacities of up to 6300kVA are available, and larger capacities can be customized to meet specific customer demands.
