SolarEdge SE14.4KUS 3-Phase Inverter
The SolarEdge SE14.4KUS inverter is designed with sophisticated digital control technology with efficient power conversion architecture to achieve superior solar power harvesting and best-in-class inverter reliability. It is designed to work with a 208 VAC 3-phase utility power grid.
Works in conjunction with power optimizers for the greatest efficiency
The fixed-voltage technology ensures the SolarEdge SE14.4KUS solar inverter is always working at its optimal input voltage over a wider range of string lengths and regardless of the environmental conditions of your solar system.
A proprietary data monitoring receiver has been integrated into the inverter and aggregates the power optimizer performance data from each PV module. This data can be transmitted to the web and accessed via the SolarEdge Monitoring Portal for performance analysis, fault detection and troubleshooting of PV systems.

SolarEdge SE14.4KUS Inverter Review
SolarEdge grid-tie inverter systems tackle all of the challenges encountered with commercial solar PV system inverters.
Increased energy yield compared to the traditional inverter system:
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.

SolarEdge's Multi-Level Reliability:
The SolarEdge multi-level reliability plan involves Design Analysis & Qualification by in-house and external experts, sub-system testing by Accelerated Life Testing (ALT) of critical components, and integrative testing of design prototypes (via HALT) and large sample groups.
As part of these efforts, tens of thousands of components have been evaluated in accelerated life chambers (burn-in, thermal cycling, humidity and so forth) as well as hundreds of products in field tests and stress tests. These tests have run for the equivalent of over 100 years (well over the expected life of photovoltaic systems). The lessons learned are invaluable and as a result, SolarEdge produces systems with unsurpassed reliability.
In order to verify that each SolarEdge product that leaves manufacturing plants conforms to our high reliability and quality standards, each component, sub-assembly, and final product are tested multiple times during production. These tests include: Automatic Optical Inspection, In-Circuit Testing, Board- and Component-Level Functional Testing, Safety Testing and Integrative Stress Testing. These rigorous screening and testing procedures, which are completed for 100% of the products we make, enable us to guarantee that SolarEdge products work as expected for the entire product lifetime.
A key element of SolarEdge's reliability strategy – and a significant differentiator relative to its competitors – is use of proprietary application specific ICs (ASIC) in its products. The best way to improve the reliability of electrical circuits is to reduce the number of components in it – this is done in SolarEdge products by replacing a large number of discrete components with a single ASIC designed specifically for the task at hand. The ASIC itself is manufactured according to proprietary design rules specifically defined to allow for the long 25 year lifetime of the ASICs. Extensive analysis and testing has been done to assure the ASIC packaging is robust enough to handle the mechanical and electro-chemical stresses experienced over 25 years of daily thermal inverter cycling.
