Grid-connected PV inverters have traditionally been thought as active power sources with an emphasis on maximizing power extraction from the PV modules. While maximizing power transfer remains a top priority, utility grid stability is now widely acknowledged to benefit from several auxiliary services that grid-connected PV inverters may offer.
The control design of this type of inverter may be challenging as several algorithms are required to run the inverter. This reference design uses the C2000 microcontroller (MCU) family of devices to implement control of a grid connected inverter with output current control.
Whatever the final design criteria a designer shall be capable of: •Determining the energy yield, specific yield and performance ratio of the grid connect PV system. •Determining the inverter size based on the size of the array. •Matching the array configuration to the selected inverter maximum voltage and voltage operating windows.
GRID-CONNECTED POWER SYSTEMS SYSTEM DESIGN GUIDELINES Assume that the minimum voltage window for an inverter is 140V. Recommended that a safety margin of 10% is used. Minimum inverter voltage of 1.1 x 140V = 154V should be used. The minimum number of modules in a string is = 154 / 26.6 = 5.79 rounded up to 6 modules
