Specific Testing for the Growing Renewable Energy and Electric Vehicle Market The growth of the renewable energy and electric vehicle (EV) industry has been explosive over the past decade. With this explosive growth come challenges. There are a number of power immunity compliance test requirements for new regulations or standards. These challenges, however, can be met through the coordination of policy, regulation and innovative technology, making renewable energy, and EV in particular, an optimum source of power for the future and clean energy.

Grid-Connected Test As renewable power sources become a larger percentage of the grid, utility companies must face a substantial threat to system reliability. There standards or certifications may involve with different purpose of testings.

For a PV inverter testing system, it usually includes:
1. DC Power Supply: to simulate output characteristic of the solar panels (array). It also requires a feature called solar array simulation function or IV curve simulation. This function is useful for MPPT performance evaluation on PV inverter devices.
2. AC Power Source or Grid simulator: to simulate different grid conditions like voltage or frequency Variation. Large inverter may also involve Low Voltage Rid Through Test or Fault Ride Through Testing that may require regenerative function on the AC power source.
3. RLC Load: to simulate AC Device Resonance to check the anti-islanding protection function and for examination the working efficiency, and maximum output capability.
4. Measurement System: DAQ, DMM and Power Analyzer to confirm the manufacturer's stated performance and to measure PV inverter output parameters, such as V, I, P, PF, current harmonics & THD.
