Title: Hybrid Solar Inverters evaluation Keywords: Hybrid energy storage, Power convertors, renewable energy Abstract: Achieving full utilization of the solar resource inevitably requires storage of excess energy during peak generation. Adding a battery to a solar inverter makes it a hybrid one. These inverters are the main steppingstone in achieving the goal of EU for decarbonization by full utilization of renewable resources. However, in order to achieve this goal their efficiency must be as high as possible during battery charging or discharging. This depends mainly on the power topology that is used. The paper presents the power topologies used in market available hybrid inverters alongside measured efficiencies during operation. Based on these data a novel power topology is presented that increased the efficiency in certain scenarios. Experimental verification of the topology during battery charging is presented to show the advantages. References Issue
