Partnering With EPEC/QT for More Efficient Solar Energy Installations

As the world becomes more electric, the renewable power is a growing industry with demand expected to increase, putting pressure on companies that supply solar energy solutions to build more efficient and effective equipment.  

采集太阳能并将其输送到电网,使其能够为家庭和企业供电,这个过程十分复杂,涉及到经过精心校准的多个设备。此外,由于太阳能公司会寻找日照稳定的地点,因此经常在难以前往的恶劣环境中建造太阳能场。要在这些偏远地区进行维修,成本非常高昂,因此保护敏感设备就变得至关重要。

nVent is helping our customers achieve critical innovations in the renewable energy industry. EPEC Solutions (EPEC) and QT Corporation (QT), known as EPEC/QT, offer efficient and low footprint solar power panel solutions like AC combiner switchboards, combiners and recombiners. The company takes advantage of nVent technologies to save space, create efficiency and reduce cost without sacrificing reliability.   

高效的采购可节省时间和资源 

交流汇流箱是太阳能系统的重要组成部分,用于将来自许多太阳能电池板链的能量组合为单一电源输出,以馈送到变压器,然后进入当地电网。These combiners are a core piece of EPEC_QT’s business. 

为了向客户提供最优的技术,EPEC_QT 工程师需要为汇流箱采购最可靠且最高效的组件。要建造汇流箱,需用到许多独立的技术,包括用于传输能量的导线、用于确保电气系统稳定的浪涌保护器和绝缘体,以及用于保护敏感设备免受恶劣环境影响的机箱。

要从许多不同的供应商处获取合适的零件,非常具有挑战性。EPEC_QT worked with nVent representatives and distributors to purchase several nVent enclosures, power conductors, insulators and surge protection devices. 通过从 nVent 为汇流箱采购多种组件,简化了 EPEC_QT 的采购和生产流程。通过使用定制的 nVent 产品,还帮助 EPEC_QT 减少了人工时间,并降低了为满足客户需求而需保留的库存数量。


提高效率和可持续性 

EPEC_QT 制造创新的汇流箱,为客户降低成本和产品占地面积。该公司的 UL 891 交流汇流配电盘可减少 40% 的占地面积,使客户能够更有效地利用空间,并生产更多可再生能源。

在设计交流汇流箱技术时,找到合适的机箱对于 EPEC_QT 而言至关重要。公司工程师需要一种理想的机箱,既能保护所有关键部件,又可以支持技术创新,同时还要减少占地面积。EPEC_QT worked with nVent to create a custom enclosure that houses the entire combiner and switchboard system.  EPEC_QT selected nVent based on their ability to design and customize the enclosure to match the specific needs of the solar industry, the repeatable quality of the enclosures and the overall value of the product.    

Additionally, to reduce the footprint of their switchboard technology, EPEC_QT engineers made the decision to eliminate copper bus connections inside the combiner and replace them with nVent flexible busbars and IBSB braids. These nVent conductors are more space efficient and cost efficient than copper busbars and offer better conductivity. They also reduce production time and labor costs because they are customized by nVent to match EPEC_QT’s exact specifications instead of being sheared and bent on site. 这使得 EPEC_QT 可以降低铜库存量,并最大限度地减少材料浪费。

“With a focus on innovation and quality, nVent continues to set new benchmarks in the industry,” said Mark Sauls, Vice President of EPEC. 

With nVent products in its combiner systems, EPEC_QT can count on its ability to deliver for its customers and continue to focus on creating innovative solutions that drive the solar energy industry forward. nVent is helping our customers achieve critical innovations for a more sustainable and electrified world, bringing new technologies without sacrificing reliability. Our solutions provide resiliency and protection and safety to critical systems and infrastructure around the globe while maximizing customer productivity.

nVent Insight: 如何才能将太阳能传输到您的电源插座?

在太阳能系统中,当太阳能电池板收集太阳光并转换为直流电 (DC) 时,电力流就开始了。然后,此直流电通过称为组串逆变器的设备转换为交流电 (AC)。“串式逆变器”得名于彼此捆绑在一起的多个“组串”太阳能电池板。通常情况下,有 12 至 24 个组串连接到每个串式逆变器,每个组串包含约 30 块太阳能电池板。

来自组串逆变器的新生成交流电随后流入交流配电盘;在太阳能行业,这称为汇流箱,是 EPEC_QT 的专长所在。The combiner’s job is to combine the power from several string inverters. 然后,汇流箱连接到变压器,变压器将太阳能系统输出的电压与当地电网的电压相匹配,从而将当地生产的该能源用于为家庭、企业、电动汽车充电设备等供电。
