The unit is a bidirectional 200kW / 1050V DC/DC overlapping power converter. As a combined buck/boost air-cooled converter, it can be set up in either charging or discharging mode. Moreover, the units can be stacked for achieving higher power with no communication between them (optional). [pdf]
[FAQS about DC system charging inverter cabinet]
DC-side systems connect solar panels directly to the battery storage without the need for an AC inverter, resulting in fewer energy conversions. AC-side systems, on the other hand, convert the DC power generated by solar panels into AC power, then store it in batteries. [pdf]
[FAQS about DC side and AC side of energy storage power station]
The charging and discharging time of energy storage power stations can vary based on the technology used.Storage Duration: This is the amount of time a storage system can discharge at its power capacity before depleting its energy capacity. For example, a battery with 1 MW of power capacity and 4 MWh of usable energy capacity will have a storage duration of four hours1.Operational Data: In practice, energy storage stations may charge during low demand periods (e.g., overnight) and discharge during peak demand periods (e.g., afternoon)2.These times can vary significantly based on the specific energy storage technology and operational strategy employed.
