NSYZC New energy integrated prefabricated chamber

TOONICE’s the full name of the photovoltaic prefabricated cabin is prefabricated modular power distribution cabin for photovoltaic power stations. It is a standardized equipment cabin that integrates, debugs, and wires core functional equipment (such as inverters, combiner boxes, high-voltage cabinets, etc.) for “power conversion, control, protection, and monitoring” in photovoltaic power stations within a factory, before transporting the entire unit to the site for hoisting and positioning. Its core features are “factory prefabrication, modular integration, and on-site rapid installation”, which has completely transformed the traditional construction mode of photovoltaic power stations that relies on “on-site concrete foundation pouring and decentralized equipment installation”. It is a core equipment for the development of photovoltaic power stations towards “high efficiency, standardization, and intelligence”.

I.Why Do Photovoltaic Power Stations Need Prefabricated Cabins?

1. Significantly Shorten the Construction Period:

The power distribution system of traditional photovoltaic power stations undergoes processes like “site leveling → foundation pouring → equipment procurement → on-site wiring → commissioning”, with a construction period of 2–3 months. In contrast, 80% of the core work for photovoltaic prefabricated cabins (equipment integration, wiring, and commissioning) is completed in the factory. On-site, only 4 steps are needed: “foundation leveling → cabin hoisting → cable connection → grid-connected testing”. The installation cycle for a single cabin can be shortened to 1–2 weeks, and the overall construction period of the power station can be reduced by over 40%.

2. Strictly Control Construction Quality and Reduce On-site Risks:

Standardized production processes (e.g., wiring in clean rooms, automated testing) are adopted in the factory, making equipment installation accuracy (such as cabinet spacing, terminal torque) and insulation performance more controllable. This avoids quality hazards (e.g., loose wiring, insulation damage) caused by on-site construction being affected by weather (rain, snow, high temperature) and variations in personnel skills. Meanwhile, the fully sealed design of the cabin reduces the erosion of equipment by on-site dust and moisture, lowering the equipment failure rate by 30%.

3. Adapt to Complex Outdoor Environments and Improve Reliability:

The cabin uses a high-strength steel structure (e.g., Q235B cold-rolled steel plate) + multi-layer protective coatings (anti-corrosion, sun protection, heat insulation), with a protection grade of up to IP54 and above (some models support IP65). It can adapt to complex environments such as extreme temperatures (-30℃ to 55℃), high altitudes (≤4000m), salt spray (coastal areas), and sand and dust (desert power stations), ensuring long-term stable operation of the equipment.

4. Simplify Operation & Maintenance and Reduce Operating Costs:

The layout of equipment inside the cabin is standardized (partitioned according to the process of “power generation → inversion → step-up → control”) and matched with an intelligent monitoring system (e.g., temperature and humidity sensors, equipment status indicator lights), allowing operation and maintenance personnel to quickly locate fault points (e.g., inverter alarms, abnormal current in combiner boxes). Some high-end models support “remote monitoring + automatic inspection” (e.g., checking the status of equipment in the cabin via cameras), reducing the frequency of on-site inspections and lowering annual operation and maintenance costs by 20%.

II. Structural Composition

The structure of the photovoltaic prefabricated cabin is designed around three core aspects: “equipment integration, environmental control, and safety protection”. As a whole, it is divided into two major parts: “cabin shell” and “internal functional units”. The specific composition is as follows:

III. Typical Application Scenarios

TOONICE’s Photovoltaic prefabricated cabins, with the characteristics of “modularization and high adaptability”, are widely used in various types of photovoltaic power stations, especially suitable for scenarios with high requirements for construction efficiency and environmental adaptability::

1. Ground-mounted Concentrated Photovoltaic Power Stations:

① Manufacturing industry: Machine factories (lathes, milling machines), cement factories (ball mills, crushers), steel mills (steel rolling machines, fans), etc., compensate for the reactive power loss of inductive loads and improve the stability of production equipment;

2.Distributed Photovoltaic Power Stations:

① Industrial and commercial distributed: For photovoltaic projects on factory rooftops or in industrial parks, prefabricated cabins can be directly installed on rooftops or open spaces in the factory area, without occupying a large amount of land, and the installation period is short (it can be connected to the grid in 1-2 weeks) without affecting the normal production of the factory;

② Agrivoltaic / Fishery-photovoltaic complementary power stations: Photovoltaic panels are built above farmland or fish ponds, and prefabricated cabins are installed at the edge of the project to avoid damaging the cultivated land / fish ponds, while adapting to outdoor humid environments (IP54 protection).

2. Photovoltaic Power Stations in Special Environments

① High-altitude power stations: Prefabricated cabins are equipped with inverters and air conditioners adapted to low air pressure (which can work normally at an altitude of 4000m) to prevent equipment from failing due to hypoxia and low temperature;

② Coastal power stations: Anti-corrosion steel structures (such as galvanized + fluorocarbon paint coating) and anti-salt-fog inverters are adopted to resist corrosion from sea breeze;

③ Power stations in cold regions: High-power heat blowers + thermal insulation layers are configured inside the cabin to ensure the normal startup of equipment in winter (minimum startup temperature -30℃).
