SS130502-832V300A(300AH1P260S)-Liquid Cooling-AC+DC-125KW+250KWh

Name: SS130502-832V300A(300AH1P260S)-Liquid Cooling-AC+DC-125KW+250KWh
Brand: Eco Power Group
Rating: 4.4 (5 reviews)

The 125kW/250kWh outdoor cabinet energy storage system can be connected to the grid and operated off-grid. At the same time, the DCDC configured in the cabinet can be compatible with the DC input of the photovoltaic system. In the energy storage link of smart grid, it can effectively regulate power resources, balance the difference of power consumption between day and night and in different seasons, adjust the surplus and shortage, and guarantee the safety of power grid. It is an important prerequisite for the application of renewable resources and an effective means to realize the intelligent management of power grid.

Layout of the rack

Varied layouts of the rack are presented in the figures below.

1.Back-to-back arrangement

For back-to-back arrangement, the minimum clearance between racks is 1500mm, and the recommended clearance between the front side of the rack and another rack is 2000mm.

2.Back-to-enclosure arrangement

Back to the wall (or other entity), the left and right sides of the cabinet should be left at least 500mm space for maintenance channel. At least 500mm space should be left at the rear of the cabinet for the cooling air duct and maintenance channel of the liquid cooling unit and PCS. Leave at least 1200mm of space on the front door for maintenance.

3.Side-by-side arrangement
