Abstract
This is a new configuration of single-phase hybrid inverter with integrated battery energy storage suitable for residential use in this white paper to maximize local consumption of solar energy and reduce reliance on support . A hybrid inverter is called a Direct Storage Hybrid (DSH) inverter. Connect photovoltaic (PV) panels to loads and grids using transformerless topologies such as HERIC, which operate at low frequencies and produce three-level square wave output voltages. An active series filter is used to cancel the harmonic content from the square wave voltage and provide a sinusoidal voltage. A bi-directional DCDC converter connects the battery to the PV panel and controls the charging state of the battery (SoC), optimizing the operation of the PV panel in both off-grid and grid-connected modes. The DSH inverter bypasses the battery DCDC converter and can be connected directly to the inverter stage, greatly increasing throughput efficiency when using batteries. This document presents his DSH inverter operation and loss analysis in off-grid mode
