SolarEdge SE10000A-US Single-Phase Inverter

SolarEdge SE10000A-US Inverter Review

High-power SolarEdge residential grid-tie inverters offer flexible design, high efficiency, small size, easy installation, and superior safety.

Increased energy yield compared to the traditional inverter system:

• SolarEdge inverters allow for more solar energy harvest due to module-level MPPT
  No power loss due to module mismatch due to power optimization per module
• Constraint free design allows for utilization of more roof area
• Easy and cost efficient maintenance for increased up-time of your PV system

SolarEdge Power Optimizer

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:

• During Installation: safe string voltage until inverter & AC supply are turned on
• Maintenance: safe string voltage with an automatic DC shutdown once inverter is turned off
• Emergency: safe string voltage with an automatic DC shutdown after grid disconnection or in reaction to high temperature
  Electrocution and fire risks are eliminated with safe voltages during installation, maintenance and firefighting

Peace of mind:

• Ability to monitor the PV system anytime, anywhere in order to guarantee optimal operation
• Module level, real-time alerts of system issues pinpointed on a virtual map

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
• Easy and cost efficient maintenance for increased up-time of your PV system

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.
