Abstract

Malaysia introduced the National Energy Transition Roadmap (NETR) to encourage the country to outline its path towards a sustainable, low-carbon energy system. Effective energy management in photovoltaic (PV) and battery energy storage systems (BESS) is essential to optimize energy use, reduce costs and reduce carbon emissions. To support the Malaysian NETR and SDG, UTeM has installed a hybrid inverter with PV and BESS at the FTKE's Solar Lab. The hybrid inverter rating is 5kW; it has a solar capacity of 4.62kW with up to 12 solar PV panels and a BESS of 10.24kWh. The hybrid inverter has unique features working modes such as general, peak-shaving, and economy modes. This study compares the energy consumption of an FTKE’s building with and without a hybrid inverter PV and Battery Energy Storage System (BESS) installation. Due to the feature of the hybrid inverter integrated with the PV and BESS, this project will analyze the impact of various modes of the hybrid inverter that can contribute to energy saving and cost reduction for FTKE's building. The main loads used for this study are the fourteen units of 3kW air-conditioning connected to the hybrid inverter PV and BESS. The logging data will be taken for two months for each mode to analyze the energy performance, like energy saving, cost reduction, and emission reduction of the FTKE's building. At the end of this project, this study will suggest the optimal modes for the operator to get significant outcomes. The result from this study can also be documented in a module so that people can better understand operating the hybrid inverter PV BESS installed in the FTKE's building.
