Description

Technical Field

[0001] The utility model relates to the technical field of energy storage, in particular to a special distribution box for an outdoor energy storage system. Background Art

[0002] The outdoor cabinet energy storage system can perfectly solve the impact caused by the problem of temporary power shortage. When the power is sufficient, a certain amount of electricity can be stored in the battery; when the power is short, the stored electricity can be transmitted to the power grid to achieve peak load regulation and grid connection. At the same time, the electricity price at night is lower than the electricity price during the day, which can realize the economic benefits brought by charging the outdoor energy storage system at night and discharging during the day.

[0003] However, traditional distribution boxes have low integration. If a system cabinet requires many functions, it is necessary to connect relatively more lines. This will make the installation process complicated and unsightly. It is also troublesome to maintain. The lines need to be cleared for troubleshooting and maintenance, and they need to be checked one by one. If they cannot be repaired, they need to be dismantled one by one, which is very troublesome.
