Abstract:
Introducing grid connected PV systems, the difference between one-phaseand three-phase power delivery is explained, highlighting the issue of
buffering storage in one-phase PV inverters. This paper presents and explains
burst operation mode as a way to improve performance of grid-connected
one-phase PV inverters without need of major additional investments. At low
power, intermittent inverter operation at optimum power for a small fraction
of time is preferred over continuous operation at low power, thus saving the
difference between operating and standby power consumption for major parts of
the operating time, and raising part-load efficiency up to optimum values. 6
