Huawei presents FusionSolar All-Scenario Smart PV & Storage Solution at Intersolar 2021

By Huawei

The solution covers “4+1” scenarios: Large-scale Utility, Green Residential Power 2.0, Green C&I Power 1.0 and Off-grid (fuel removal) Power Supply Solutions and Energy Cloud, accelerating the shift to low-carbon generation.

With the global commitment to net-zero and the inevitable need to build a new power system based on renewable energy, the PV industry has become a key pillar in achieving carbon neutrality.

● PV power generation will become the future’s main energy source and will become more available for all.

● Energy storage will become a necessary enabling technology to move renewables from adapting to grids to enhancing them.

● Low-carbon will run through all aspects of our lives.

The key to carbon neutrality is to build a new power system with renewables as its main source, featuring 1) a high proportion of renewable energy, 2) a high proportion of power electronic equipment, 3) a high degree of digitalization, and 4) a high degree of intelligence.

Huawei will leverage its advantages in digital and power electronics to achieve low-carbon power generation.

1. Large-scale Utility Scenario: Creating a Future-proof Smart PV Generator

Huawei offers a suite of key products, including a Smart PV Controller, Smart Transformer, Smart-array Controller and PV Plant Management Systems for utility scale scenarios. The solutions have the advantages of high yields, smart O&M and safe & reliable grid forming with key technologies and features such as Smart IV curve diagnosis 4.0 and Smart String-Level Disconnector, which can handle DC input reversal connect, backflow and internal short circuits, avoiding the spread of inverter faults, which may cause fire in some special cases.

With the application of 210mm high-current modules, string current will reach 20A, with a conventional inverter generally having a limitation on  DC current. The Huawei Smart PV Controller (e.g. SUN2000-215KTL-H3) supports a maximum MPPT current of 100A and can connect up to 5 strings, effectively overcoming the problem.

At Intersolar, Huawei also showcased its all-scenario smart string energy storage solution. In traditional energy storage related solutions, the difference in battery modules can trigger mismatches, resulting in degradation of battery capacity, fast attenuation, difficult O&M and high risk. With the integration of digital information, power electronics and energy storage technologies, Huawei leverages the controllability of power electronics to solve the inconsistency of lithium batteries, bringing down LCOS by 20%.

2. Green Residential Power 2.0

The upgraded Green Residential Power 2.0 solution highlights the innovative “1+3+X”structure. With the Smart Energy Controller at its core, it is equipped with three key components— the optimizer, the smart string ESS and the Green Power Cloud to build an intelligent power ecosystem. The Green Residential Power 2.0 solution, focusing on smart power generation, storage and smart power consumption with multiple active safety features, can lower home energy bills and allow homeowners to achieve a low-carbon life.

With the application of optimizers, Huawei enables homeowners to increase power generation by up to 30%. Combined with smart string ESS and the Green Power Cloud, the system can increase the self-use ratio of green power to over 95%, minimizing dependence on the grid and reducing electricity bills.

Safety remains the top priority for smart PV solutions in a residential scenario. On the rooftop, a full series of intelligent arc protection and rapid shutdown technologies are applied to achieve zero voltage and zero arc in emergency situations. For energy storage, Huawei adds three layers of protection to achieve active safety, comprising of AI-powered internal cell short circuit diagnosis to avoid fire hazards, cell-level temperature control to detect overheating, and optimizer-enabled 0V rapid shutdown for safer installation and maintenance.

When it comes to smart power consumption, Huawei has released a brand new digital feature – PV, Storage & Consumption AI Synergy. Based on big data learning of weather and user electricity consumption habits, AI can accurately predict future PV power generation and household electricity consumption. Accordingly, it can optimally control the charging and discharging of energy storage under three different scenarios: sunny days, cloudy and rainy days and smart homes mode. With this technology, it can help maximize green electricity revenue in each scenario and effectively increase the ratio of self-consumed green electricity.

Compared with the 60% pure solar scenario, moving  to an 85% of PV with storage scenario, Green Residential Power 2.0, combined with the PV, Storage & Consumption AI Synergy function can now further increase the self-consumption ratio of green power to more than 95%.

3. Green C&I Power 1.0: Enabling Green Power to empower all industries

Huawei launched its new C&I solution earlier this year, to address four different application scenarios: solar only, storage only, solar + storage + charging and off-grid. With the application of optimizers and the smart string energy storage system, the solution can improve energy yield by 30% and energy storage power by up to 15%. Huawei inverters support intelligent AFCI arc protection and automatically shut down within 0.5s, ensuring the active safety of systems.

4. Off-grid (fuel removal) Comprehensive Power Supply Solutions: Green and Inclusive Power Supply to Bridge the Energy Divide

Some 900 million people across the globe currently have no access to grid power or live in areas with an unstable power supply. Diesel generators (DGs) are highly polluting, costly, difficult to maintain and noisy, seriously affecting the normal life of residents and restricting local economic development.

Huawei showcased at Intersolar its full series of off-grid (fuel removal) power supply solutions, called iPowerCube. This offers a full series of M\S\P and is able to be applied to both industrial production and livelihood scenarios. iPowerCube can reduce power generation costs by over 60% and help to promote green development and bridge the energy divide.

5. All-scenario digital management + AI intelligent application

Benefiting from the Energy Cloud, customers will have access to All-scenario PV and Storage power plants. Adhering to the concept of all-scenario refined management, Huawei enables module-level monitoring on the PV side, while allowing pack-level 3D visual management on the storage side. At the same time, the combination of big data analysis and AI intelligent applications (such as Smart IV diagnosis, an SDS intelligent DC power generation system and PV, Storage & Consumption AI Synergy) will allow PV and storage power plants to perform automatically.

Huawei is also committed to building a safe and credible digital platform to open data interfaces to a wide range of partners in an effort to break new ground in energy services and achieve win-win cooperation.

The new power system supported by renewables continues to drive global energy transformation, and the commitment to carbon neutrality accelerates extensive social and economic change for sustainable development. Leveraging its advantages in digital and power electronics technologies, Huawei Digital Power will continually integrate cutting edge innovations, such as watt and thermal energy storage and cloud and AI technologies, into its products to continue the journey with its customers and partners towards clean power generation, energy digitalization, transportation electrification, green ICT infrastructure and integrated smart energy to build a better and greener future.
