Large-scale Solar Energy Storage System Solution

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.
