The development of inverters specifically for solar applications began around this time, with the primary goal of converting the DC generated by solar panels to usable AC power. One major breakthrough was the introduction of pulse-width modulation (PWM) technology in.
This fact sheet provides background information on microgrids with suggested language for several up-front considerations that can be added to a solar project procurement or request for proposal (RFP) that will help ensure that PV systems are built for future microgrid .
