In June 2026, DL/T2041-2025 "618 New Policy" was officially implemented, directly breaking the hard constraint of "transformer reverse load rate not exceeding 80%" that has plagued the industry for six years, and distributed photovoltaics officially entered the era of three color zoning flexible management. The new policy directly unfreezes over 50GW of existing photovoltaic projects, and the industry predicts that the newly installed capacity of distributed photovoltaics in China will exceed 80GW by 2026. Based on a 15% -20% standard energy storage ratio, the energy storage supporting space released by existing projects alone will reach 15-20 GWh.

The energy storage system in Taiwan has been upgraded from the end of the power grid to the core "skeleton" of a new type of power system. Leading companies such as Sunac, Longi, and Yuanjing have gathered to release new products, and the track is full of enthusiasm. But when the vast majority of energy storage integrators and equipment manufacturers focus on capacity ratio, cycle efficiency, and business models, they overlook an implicit red line that can directly terminate the project - environmental compliance.

I、 Deadly problem of landing: Energy storage not only needs to be able to store, but also needs to be 'quiet'
Large centralized energy storage power stations are located far away from residential areas, so there is almost no need to worry about noise. However, the energy storage in the station area and industrial and commercial energy storage all adopt on-site consumption mode, and the box is adjacent to villagers' residences, schools, hospitals, and clubs, which puts great pressure on noise control.

II. Core pain points of energy storage noise
The coordinated operation of energy storage equipment fans and PCS results in a high base of native noise. The environmental impact assessment and acceptance of the project must strictly follow the red line of the national standard noise limit. Currently, there are three major flaws that can cause project jamming.

1. Space constraints and contradictions
To save space, the ventilation openings are designed to be relatively small, and the high-speed airflow generates high-intensity aerodynamic noise.

2. Traditional solution for heat dissipation failure
Soundproof cotton sealing and enclosed soundproof enclosures can reduce noise, but the wind resistance increases significantly, the heat dissipation of the battery cells is blocked, and high temperature power limit protection is frequently triggered, even posing a safety hazard of thermal runaway. 3. Low frequency disturbance with no solution
The low-frequency noise of the fan has strong penetration and long propagation distance, which easily induces residents' "low-frequency restlessness". A large number of projects have been forced to shut down for rectification due to continuous complaints.

The long-standing engineering paradox in the industry: noise reduction equals wind blockage. Nowadays, with the large-scale deployment of energy storage, this contradiction has become the first hurdle that must be overcome before all projects are implemented.

III. Technological breakthrough: Multi functional noise reduction louvers (balancing ventilation, noise reduction, protection, and installation requirements)
The industry has long abandoned the remedial idea of installing sound insulation accessories in the later stage, and the new technological trend is to integrate the soundproofing structure into the ventilation components in advance. Huaxia New Energy's multifunctional noise reduction louvers integrate acoustic and fluid dynamics design to solve multiple contradictions in energy storage engineering using quantitative measured data.

1. Dual optimization of acoustics and flow field, achieving bidirectional standards of noise reduction and low wind resistance
Adopting an impedance composite noise reduction structure, the stable noise reduction across the entire frequency band is ≥ 13dB (A), and the day and night values are better than the national standard control standards, completely avoiding the risk of low-frequency noise complaints. Paired with exclusive wing shaped guide vanes, it smoothly channels the airflow, minimizes wind resistance, and does not block the heat dissipation ducts of the battery cells. It operates at full load for 24 hours without high temperature alarms, eliminating thermal safety hazards from the root.

2. IP54-IP65 full range waterproof and dustproof customization, suitable for all outdoor energy storage environments
Abandoning one size fits all standardized protection, customizing protection levels according to usage scenarios and needs, and accurately controlling project renovation costs.
Industrial and commercial parks with rain shelters and indoor energy storage compartments: IPX3-1PX4 is selected to prioritize maximizing ventilation efficiency and reducing energy consumption during fan operation. Open air energy storage stations and unshielded boxes in rainy and typhoon areas: customize PX5 with the highest waterproof level. In rainstorm and continuous rainy environments, water vapor backflow is prohibited to avoid corrosion and short circuit of internal lines.

3. Ultra thin modular multi-directional installation, compatible with all new and technological renovation projects

The thinnest thickness of the product is 102mm, with an ultra-thin modular structure that meets both market demands.
(1) New energy storage project: supports three installation methods: external installation, internal installation, and embedded convex installation, which can be integrated into the integrated design of energy storage equipment in advance. Minimally invasive modification, high noise reduction, and strong outdoor protection ventilation accessories will become a mandatory requirement for the project

(2) Renovation project: Supports direct replacement of old louvers in situ, without the need to modify the cabinet body during construction. Only the original louvers can be removed for hole installation, greatly reducing labor and renovation costs. Advance layout of integrated ventilation and noise reduction solutions can not only avoid operational risks such as resident complaints, project shutdowns, and environmental penalties, but also create exclusive and differentiated competitive advantages in the homogenized track.

IV、 In the era of refined operation of energy storage, noise compliance is a core competitive advantage that must be competed for

The release of massive energy storage installations during the 618 New Deal is only a superficial dividend, and deeper industry changes are forcing the energy storage industry to shift from aggressive expansion to refined long-term operation. In the future, energy storage boxes will be everywhere in urban and rural areas, and regulatory and public requirements for the environmental friendliness of energy storage facilities will only continue to rise. Noise control will be listed alongside safety and economy, becoming the three core indicators for evaluating the quality of energy storage systems. The golden opportunity for energy storage in the Taiwan region has been fully opened, and many projects blindly pursue installed capacity, ignoring the core contradiction between thermal and noise balance, ultimately getting stuck in the implementation stages such as environmental impact assessment and acceptance. HUAXIAVENT multifunctional soundproofing and noise reduction louvers provide a one-stop solution to pain points, while simultaneously considering efficient noise reduction, sufficient ventilation, outdoor waterproofing, and simple modular installation. They are the core basic supporting facilities to ensure the long-term stable and compliant operation of energy storage projects
