Solaredge.SE9KUS.Three-Phase Grid-Tie Inverter

Solaredge.SE9KUS.Inverter Review

Solaredge.grid-tie inverter systems tackle all of the challenges encountered with both residential and commercial solar PV system inverters.

Increased energy yield compared to the traditional inverter system:

• 由于模块级MPPT，Solaredge逆变器允许更多的太阳能收获
  No power loss due to module mismatch due to power optimization per module
• 限制性设计允许利用更多屋顶区域
• 简单和高效的维护费用增加up-time of your PV system

Solaredge电源优化器

The SolarEdge power optimizer is connected by installers to each module or embedded by module manufacturers, replacing the traditional solar junction box. Therefore, it must be as reliable as the module itself with the ability to withstand the same environmental conditions to which the module is exposed.

The essence of the SolarEdge reliability strategy is a physics-based multi-level method of failure point identification. Providing a warranty for a proven 25 year system operational lifetime was enabled through a combination of reliability-oriented design rules. With a selection of top-tier suppliers and acceptance testing of their components, which were manufactured in well-controlled environments, accelerated lifetime testing of the system (and its components) was conducted up to the wear-out point in order to determine when the product will fail, at what rate and by which failure mechanisms.

Safety:

• 安装过程中：安全串电压直到变频器和交流电源打开
• 维护:安全字符串电压智慧h an automatic DC shutdown once inverter is turned off
• 紧急情况：栅格断开或在高温反应后，安全串电压具有自动直流关闭或高温反应
  在安装，维护和消防期间，使用安全电压消除电局和防火风险

Peace of mind:

• Ability to monitor the PV system anytime, anywhere in order to guarantee optimal operation
• 模块级别，系统问题的实时警报在虚拟地图上查询

Increased energy yield:

• More energy due to module-level MPPT
• Mismatch power losses eliminated
• Shade tolerance assures maximum power harvest under trees and other obstructions
• 简单和高效的维护费用增加up-time of your PV system

Solaredge.'s Multi-Level Reliability:

SolowEdge多级可靠性计划涉及内部和外部专家的设计分析和资格，通过加速寿命测试（ALT）的关键组件的子系统测试，以及设计原型（通过HALT）和大型样品组的整合测试。

作为这些努力的一部分，已经在加速的寿命室（烧伤，热循环，湿度等）以及数百种野外试验和压力测试中评估了数万个组件。这些测试已经运行相当于100多年（良好的光伏系统的预期寿命）。所学到的经验教训是宝贵的，因此，SolarEdge生产具有无与伦比的可靠性的系统。

为了验证将制造工厂符合我们的高可靠性和质量标准，每个组件，子组件和最终产品的每个Solaredge产品在生产过程中多次测试。这些测试包括：自动光学检测，电路测试，电路板和组件级功能测试，安全测试和集成压力测试。这些严格的筛选和测试程序，完成了100％的我们所做的产品，使我们能够保证Solaredge产品按预期的整个产品寿命工作。

SolowEdge的可靠性战略的一个关键因素 - 以及相对于竞争对手的重要区别 - 是在其产品中使用专有应用特定IC（ASIC）。提高电气电路可靠性的最佳方法是减少其中的组件数量 - 这是通过更换大量离散组件，其中单个ASIC专门为手头的任务设计了大量的离散组件。ASIC本身根据专门定义的专有设计规则制造，以允许ASIC的长期25年的寿命。已经进行了广泛的分析和测试以确保ASIC包装足够强大，以处理25年的日常热逆变器循环超过25年的机械和电化学胁迫。
