SHENZHEN, China, Dec. 21, 2021 /PRNewswire=KYODO JBN/ --

The energy storage project at the headquarter of Haitai Solar has recently been

connected to the grid. The project uses Huawei's industry-leading Smart String

Energy Storage System (ESS) to store and supply power for Hebei's first PV

certification lab, which has been installed recently.

Huawei provides the entire Smart String Energy Storage Solution, including the

ESS, DC Box, Smart Power Control System (Smart PCS), and Smart Array Controller

(SACU).

Huawei's smart PV+storage solution outperformed competitors' in safety,

reliability, market reputation, brand influence, and economic benefits.

"Safety is our top concern and the main reason why Haitai Solar chose Huawei's

ESS. It provides four-layer protection and proactive warning functions, which

impressed us." said the head of the energy storage business division of Haitai

Solar. Huawei and Haitai Solar will continue to increase technical exchanges

and work closely in the energy storage industry.

The system has been in use for more than a month and has seen satisfactory

benefits brought by Huawei's Smart String Energy Storage Solution. According to

the head of the project, the ESS charges when electricity prices are low and

discharges when electricity prices are high. If the ESS charges and discharges

once a day based on the current peak-valley price difference in Tangshan, the

investment can be recovered in about eight years. As the peak-valley price

difference increases, the return on investment period will be even shorter. The

lifespan of the entire system is at least 15 years, providing great economic

benefits.

Compared with other vendors' solutions, Huawei's ESS implements refined battery

pack-level management and increases the charge and discharge capacity by more

than 15%. In this way, it increases revenue and can recover costs quicker.

However, as the coal price rises and control tightens over energy consumption

volume and intensity, many provinces across the country have increased the

restrictions on power usage, resulting in many enterprises announcing

production curtailment or suspension. Huawei's energy storage solution used in

this project is well integrated with the previously installed PV modules. The

PV modules charge the ESS during peak PV power generation, and the ESS

discharges during peak power consumption. In this way, the production capacity

of the enterprise is more resilient, more green power is used, and grid

overload is reduced.

Huawei Digital Power is committed to integrating digital and power electronics

technologies to build a smart PV+storage solution that is more efficient,

stable, and safe, and promoting the energy revolution for a better, greener

future with industry partners.

Haitai Solar is a high-tech enterprise focused on green energy with five

business divisions: Photovoltaic modules, Utility Scale Power Plant,

Photovoltaic Brackets, Energy Storage, and Hydrogen Energy. Since its inception

in 2006, the company has been committed to systematically providing more value

to global customers. As an intelligent new energy provider, Haitai Solar will

continue to promote new energy development with quality and technology

development to lead the green energy revolution.

Huawei Digital Power covers several business domains: smart PV, data center

facility, site power, mPower, embedded power, and integrated smart energy.

Huawei Digital Power serves one-third of the world's population across more

than 170 countries and regions. The company's vision is to integrate digital

and power electronics technologies, develop clean power, and enable energy

digitalization to drive energy revolution for a better, greener future.
