The steadily growing share of converter connected distributed generations have been receiving more attention in the last few years because of their high efficiency and superior reliability. This paper presents a novel remote power control method of a small single phase grid connected inverter using a DC-DC converter and an ADR101 serial data acquisition card. Before grid connection characteristics of the inverter are programmed for a desired input DC voltage versus output power. Input dc voltage of the inverter is adjusted by controlling the DC-DC converter. A PC receives the required output power signal from a dispatch center via the Internet. The PC measures the power being fed by the inverter to the grid and uses an ADR101 to control the DC-DC converter to adjust the power flow to the grid. This paper presents the control scheme and test results of a 250 W grid connected inverter.
