Abstract
A method, apparatus, and system to control and test a solar inverter are provided. The method commissions a solar inverter of a solar plant before it is placed into power production. The commissioning process verifies that the inverter to be tested is functioning as intended by connecting a first inverter to the inverter to be commissioned, and using the first inverter to emulate the power grid without being connected to the power grid, and circulate reactive and limited active power between the first inverter and the inverter to be commissioned.
