AMETEK Programmable Power will be offering a fully automated EN50530 test solution that utilizes three core ‘Surround the Inverter’ elements: the TerraSAS Solar Array Simulator, MX/RS Grid-Simulator and CTS Compliance Test System. The programmable power products and systems simulate the output of solar arrays, the loads applied to the output of the inverter and the interface with the grid, providing a comprehensive and energy efficient means of testing PV inverters.

Problem

Testing to the EN50530 standard for efficiency of grid-connected PV inverters normally requires an engineer or technician to be present to manually progress through each curve set.

Solution

The automated test system is configured and controlled via AMETEK ‘Windows’-based software that enables users to select the EN50530 Test regime, connect the inverter under test, start the test, walk away and return to collect the report. The system provides a turn-key approach to testing the maximum peak power tracking (MPPT) characteristics for grid-tied inverters and DC charge controllers. The ability to simulate virtually any fill factor or solar cell material allows the customer to validate the MPPT algorithm with a power source. Hardware control is accomplished by an application running on the local controller that communicates directly to the PV simulator using RS422, which operates as a dedicated IV curve generation processor.

Applications

PV inverter manufacturers and testing houses.

Platform

TerraSAS Solar Array Simulators are available as single- or multi-channel systems from 5kW-1MW (80V-1500V). Single/Three-Phase MX/RS Series Grid Simulators are available from 15kVA-1MVA and offer an innovative Energy Regeneration mode that returns up to 85% of the electricity generated by the inverter back to the grid.

Availability

Shipment of the EN50530 solution is expected to begin in early Q2 of 2012.

The utility-scale PV market is poised for exponential growth and yet the industry still has many fundamental opportunities to improve on standards and best practice. Tracker shade loss has been one of those topics that deserve more attention, but has been typically handled by derate factors rather than trying to accurately forecast the loss over the life of the system. Join Nextracker’s subject matter experts, Aron Dobos and Neelesh Umachandran, and Rounak Kharait, director of solar energy assessments at DNV, for a webinar about why shade modeling matters and recommendations on what the solar industry should do about it.

Join us to hear directly from the CTOs and heads-of-research from the top-20 cell/wafer producers to the PV industry today. The event will focus on predicting the key metrics underpinning the next big shift to n-type with answers to the key questions: When will the transition to n-type happen? Which companies will be first to 10 GW capacity and production? Who will be the key equipment suppliers for the new production lines? Which n-type process flow/architecture will emerge as the front-runner? What will polysilicon purity and wafer thickness levels look like for optimized n-type manufacturing? What will the upstream poly/wafer supply-chain look like in 5 years from now?
