24-Hour Green Power Residential Solution Redefines Power Consumption

Enjoying clean solar energy day and night is not a fiction anymore.
Huawei launched the world's first 24-hour green power residential
solution, enabling a carbon-neutral lifestyle. It is estimated that
utilizing this sustainable system translates to zero-emission and
equivalent to planting 1300 trees per year.

Optimizers could maximize PV modules' energy yields (up to 30%)
regardless of shading and inconsistent orientations. The AI-powered AFCI
proactively mitigates fire risk with rapid shutdown technologies,
achieving zero voltage on the rooftop and zero arc risks for dual-layer
protection.

Huawei's residential intelligent battery LUNA2000 is the highlight of
the exhibition. This battery features a streamlined appearance and uses
lithium iron phosphate cells for upgraded safety. It adopts modular
design and supports flexible power expansion (5–30 kWh). Each battery
pack has a built-in energy optimizer and supports independent charge and
discharge management. Old and new battery packs can be used together to
fully unleash the potential of each battery.

"X" Key AI Applications Reconstruct PV

  • Intelligent tracker control algorithm reconstructs power generation: The
    neural network-based AI training and modeling enable trackers to be
    adjusted to the optimal angles, achieving better convergence of bifacial
    PV modules, trackers, and multi-MPPT smart PV controllers. This enables
    the entire DC system to reach the optimal status and unleashes the
    potential of each PV string. The test results show that the algorithm
    can increase the energy yield by more than 1%.
  • Smart I-V Curve Diagnosis 4.0 reconstructs O&M: Smart
    I-V Curve Diagnosis 4.0 is further upgraded and has reached the
    industry's highest level with a detection consistency and accuracy of
    over 95%, as certified by China General Certification Center. Besides,
    Smart I-V Curve Diagnosis 4.0 can adapt to more complex PV module
    scenarios, such as bifacial, shingled, and mixed PV modules. It takes
    only 15 minutes to complete online full detection for a 100 MW PV plant
    and automatically generate a report. 5 GW global application, combined
    with big data mining and AI self-learning, enables continuous
    optimization of the fault model for more accurate and sound judgment,
    making Smart I-V Curve Diagnosis one generation ahead of the industry
    level.
  • Intelligent grid connection algorithm reconstructs grid connection: The
    grid parity era witnesses an increasing penetration rate of new energy
    sources. How to operate stably in weak power grids becomes a challenge
    in the industry. Huawei AI BOOST intelligent grid connection algorithm
    boasts accurate measurement and stable control. The PV system can run
    stably in various poor power grids (including the power grid with an SCR
    of 1.5), without grid disconnection or derating. This helps smart PV
    become the main energy source as well as a high-quality energy source.
  • Intelligent AFCI reconstructs safety: Huawei is the first in
    the industry to integrate the AI algorithm into AFCI, enabling three
    unique features. First, the AI model continuously and efficiently learns
    more arc features, forming a database with over millions of arc
    features. Second, more than 92 arc feature comparison points are
    identified and analyzed based on the powerful computing capability of
    the local chip to implement precise detection and accurate reporting for
    better protection. Third, the power system is shut down within 0.5s,
    which is much shorter than 2.5s specified in the industry standard.
  • Auto-mapping of PV modules reconstructs customer experience:
    Huawei's distributed inverters incorporate the Digital Turbo technology
    for the first time. The built-in AI image recognition technology can
    intelligently generate the physical layout of PV modules within 5s,
    saving 86% configuration time and avoiding manual errors.

New Platform + New Ecosystem, Accelerating Digital Transformation

Based on the FusionSolar AI platform, Huawei uses the "platform +
ecosystem" mode to gather different types of partners for the digital
transformation of the new energy industry through the ecosystem.

Huawei always adheres to the concept of "openness, cooperation, and
win-win" and works together with customers and partners to build a smart
PV ecosystem. Huawei Smart PV has cooperated with global key partners
to build innovation centers and build a prosperous industry ecosystem
with manufacturers of PV modules, transformers and trackers.

Whitepapers and Industry Certifications

  • China Electric Power Research Institute (CEPRI) Nanjing
    Branch issued Huawei the industry's first certificate under the new
    national standard for solar inverters. This is the first certification
    being issued under the new national standard (GB/T 37408 Technical
    Requirements for PV Plant Grid-supporting Inverters). Huawei's smart
    string inverter has become the first in the industry to pass the new
    national standard assessment, setting a new benchmark for the industry
    and grid-supporting technology.
  • Huawei together with leading testing and certification organization
    China General Certification Center (CGC) releases the String PV Smart
    I-V Curve Diagnosis Technological White Paper and Technical White Paper
    on DC Arcing Intelligent Detection (AFCI) for PV Systems. At the same
    time, Huawei received the industry's highest level I-V certificate and
    industry's first highest-level AFCI certificate from CGC.

This year, participants could also visit Huawei booth at SNEC via live broadcast available in Chinese and English, https://solar.huawei.com/apac/snec2020.

Huawei also showcased its Digital Power's full products and
solutions, including site power, smart data center, power module, and
vehicle-mounted power. Huawei keeps innovating by combining power
electronics, ICT, AI, big data, and cloud technologies to help build a
simple, green, smart, and reliable energy target network as the energy
base for the digital world.
