Teardown of a large solar inverter. The ABB TRIO 20 kW inverter is a three-phased inverter built around many TO-247 IGBT & Schottky diodes.
The inverter's main function is to convert variable-voltage DC from sunlight on the PV panels or battery storage to a specific AC voltage and frequency for use by appliances and feedback to the grid. The AC output varies by region, with 60-Hz 115 VAC used in North America and 50-Hz 230 VAC in much of Europe. (Note: The passage originally mentioned 'sunlight on the PV panels or battery storage', which answers the question, but it was not at the beginning of the passage. I have rephrased the beginning to make it flow better with the question.)
A typical single-phase Photovoltaic (PV) inverter, like the SMA board, uses a digital power controller, the DSP, and a pair of high-side/low-side gate drivers to drive a pulse-width modulated (PWM) full-bridge converter. This converts the variable DC voltage from the solar panels into a stable AC voltage suitable for the power grid.
The AC power produced by a solar inverter varies by region. In North America, the AC output is typically 60 Hz and 115 VAC, while in much of Europe it is 50 Hz and 230 VAC. Enter SMA Solar Technology AG, headquartered in Germany, with their "Sunny Boy" series of solar inverters.
In a PV inverter, a capacitor is used to store the energy that must be stored and retrieved by the inverter. It is located on the PV bus and has to be large enough to control the voltage ripple across the bus. Failure to do so would negatively impact MPPT (Maximum Power Point Tracking) accuracy.
The SMA Solar power inverter card is a reliable and high-performing option due to its use of very high quality active and passive components. Figure 2: SMA Solar Technology AG solar power inverter card for “Sunny Boy” series.
