- An analysis has been made of the most important electrical parameters related to photovoltaic grid-connected inverters below 10 kW. To achieve this, a compilation of up to 50 manufacturers, various brands and up to 500 different models has been prepared and updated to February 2008. Datasheet and manuals have been compiled, noting down their electrical output and input characteristics. Different and important aspects with respect to performance of some PV grid-installation have been analyzed: the number of different models for values of power; topology option; operational DC parameters range (such as nominal power, maximum power, nominal current, voltage), operational AC parameter range (such as nominal power, maximum power, nominal current, voltage), inverter conversion efficiency vs nominal power and normalized inverter size and weight.
