Solution Overview & Testing Methodology
A photovoltaic or PV inverter converts the direct current (DC) output of a solar cell or array into an alternating current (AC) that can be fed directly into the electrical grid (Grid Tie), used by a local electrical grid (Off-Grid), or both (Hybrid Inverters). The PV Inverter is a key component in a photovoltaic system, allowing the use of household and commercial AC powered devices.
Our test instrumentation provides means to further the development, reliability, and validation of grid-tied, off-grid, and hybrid solar PV inverters that will eventually be used in commercial and household applications for years to come. We do this by integrating features into our testers that, for example, allow performance testing of inverter behavior during voltage and frequency fluctuations found on the grid. And we can do this either by standalone instrumentation or integrated into an automated test system (ATE).
