户外光伏柜

概述 Overview

户外光伏柜是分布式 / 集中式光伏发电系统的户外专用电气设备，主要承担光伏电能的汇流、逆变监测、并网控制、安全保护及数据采集功能，可直接在室外环境下运行，无需额外建配电房，广泛应用于工商业屋顶光伏、地面光伏电站、户用光伏等场景。

其核心价值体现在三个方面：

集成化管控：整合汇流单元、保护单元、计量单元、并网单元及智能监控单元，简化光伏系统接线，降低现场施工难度。

户外适应性：柜体采用防腐、防尘、防水、抗紫外线设计，能耐受高低温、潮湿、沙尘等恶劣户外环境。

安全并网保障：内置防孤岛保护、过压 / 欠压保护、过流保护、防雷浪涌保护等装置，确保光伏系统与电网的安全稳定互联，同时满足电网并网标准要求。

Outdoor photovoltaic cabinet is a specialized electrical equipment for distributed/centralized photovoltaic power generation systems, mainly responsible for the collection, inversion monitoring, grid control, safety protection, and data acquisition functions of photovoltaic energy. It can operate directly in outdoor environments without the need for additional distribution rooms and is widely used in industrial and commercial rooftop photovoltaic, ground photovoltaic power stations, household photovoltaic and other scenarios.

Its core values are reflected in three aspects:

Integrated management and control: Integrating combiner units, protection units, metering units, grid connected units, and intelligent monitoring units to simplify photovoltaic system wiring and reduce on-site construction difficulties.

Outdoor adaptability: The cabinet adopts anti-corrosion, dustproof, waterproof, and UV resistant design, which can withstand harsh outdoor environments such as high and low temperatures, humidity, and sand and dust.

Safe grid connection guarantee: Built in anti islanding protection, overvoltage/undervoltage protection, overcurrent protection, lightning surge protection and other devices ensure the safe and stable interconnection between the photovoltaic system and the power grid, while meeting the requirements of grid connection standards.

1. High level protection performance, suitable for all outdoor environments

Made of stainless steel, anti-corrosion steel plate and other materials, with a salt spray test lasting over 720 hours, it can resist corrosive environments such as coastal salt spray and northwest sand and dust, forming comprehensive protection.

The protection level is mostly IP65 (completely dust-proof, anti low pressure water spray), and can reach IP67 in special scenarios. With the design of rainproof brim, waterproof rubber strip, etc., it completely isolates rainwater; Internal copper bars are treated with tin plating to reduce the risk of corrosion.

2. Comprehensive security protection to eliminate operational risks

Equipped with multiple protections such as overvoltage/undervoltage, overcurrent short circuit (breaking capacity ≥ 65kA, response<0.02 seconds), lightning surge protection (standard 40kA, can be raised to 100kA in thunderstorm areas), etc., to cope with various risks of power grids and equipment.

Standard anti islanding protection device, millisecond level power-off and anti reverse power transmission when the power grid is abnormal; Partially equipped with leakage and grounding protection, certified by authoritative authorities to ensure the acceptance of the power grid.

3. Multi energy adaptation and efficient operation to enhance energy value

Can be connected to photovoltaic, wind power and other power sources, compatible with multi-mode input and output of mains power and energy storage; Support "photovoltaic priority" scheduling, automatically switch energy storage mode when the mains power is cut off, suitable for photovoltaic rich areas such as the northwest.

Using high-quality components, the inverter has high efficiency and supports redundant protection; Scientific heat dissipation design stabilizes the temperature inside the cabinet, reduces losses, and extends its lifespan.
