ECE relies on advanced lithium iron phosphate battery technology, which can provide large-scale energy storage systems, distributed energy storage systems and microgrid systems. The large distributed solar optical storage and power generation system is composed of photovoltaic modules, converter, AC-DC junction boxes and commercial
large scale solar battery storage batteries. The modules of photovoltaic modules transmit electricity to energy storage converters through photovoltaic junction boxes. The EMS system intelligently manages the distribution and use of electricity, and delivers power in real time according to the requirements of the use scenarios.These solutions can be used for frequency regulation, voltage compensation, frequency regulation and power quality management in the power system.
Detail of Large-scale Solar Energy Storage System Solution
The photovoltaic array is a complete power generation unit, consisting of any number of photovoltaic modules and panels. Many 450W-580W photovoltaic modules composed of crystalline silicon cells form photovoltaic arrays installed in series on various types of supports.
Photovoltaic arrays are typically installed on residential roofs, commercial roofs and ground utility scale systems (power stations or industrial parks, etc.).
The battery system is composed of lithium iron phosphate class A cell with good safety performance and long life. A single battery pack is 64V280AH, and 12 batteries are connected in series to form a 215 KWh battery cluster. Multiple battery clusters are connected in series to reach the final required capacity of the system. The battery system stores the photovoltaic power generation energy or the trough energy of the power grid to release when the load is needed, to meet a variety of application scenarios.
