Whether your solar inverter is stand-alone or tied to the grid, Silicon Labs isolation and current sensor products provide the necessary reliability and safety for your design. We've helped boost energy capacity by 3,600 megawatts over the past five years through integration into about 7.3 million solar inverters.
Inverters
After the array of solar photovoltaic cells capture and convert the optical energy into electrical energy, the dc-dc boost increases the dc voltage from the panels, then outputs ac voltage for connection to the grid after filtering. The dc boost and inverter stages require isolated gate drivers, like the Si82xx gate drivers for driving the power switches (MOSFETs, IGBTs or in new designs, SiC or GaN FETs).

Purpose |
|
Current shunt sense amplifiers with digital or analog output* |
Communication & Control
The entire system can be monitored and controlled via a communication bus. The bus is isolated with digital isolators and digital isolators with integrated DC/DC power converters like the Si86xx and Si88xx.
