Performance Analysis of Solar Inverter

Abstract

In this paper, the performance analysis of solar inverter has been carried out. For this analysis, the experiment has been conducted over two different input and different capacity of solar inverter. This Inverter was connected with the PV system of 1.8 kWp and the storage battery bank for supplying the domestic load. Battery storage is used here for supplying the electricity when PV power is insufficient or supplying power in night time and also used for storage of extra PV power when load is insufficient or not matched with supply. The result of these experiments shows that the efficiency of inverter is very less when it works under load condition. And it also conclude about necessity of battery in domestic load for maximum PV power utilization and reducing the cost of PV system. And experiment also shows the performance of inverter in different climate condition as load varies with conditions. This paper also discusses about the different types of inverter and their techniques, which are used in PV systems. In this thesis, Simulation of inverter has been also carried out with the SPWM technique.
