I need a full engineering design for a residential-scale hybrid inverter that can seamlessly switch between my rooftop solar array, a lithium battery bank and the utility grid. The unit must accept solar DC input yet always remain grid-interactive so excess production is exported and the batteries are charged intelligently when tariffs are low. Key goals include 3–5 kW continuous power, true sine-wave output, high conversion efficiency, islanding protection that complies with typical residential standards (IEEE 1547 or equivalent) and a user-friendly monitoring interface (Wi-Fi or RS-485 preferred). Because I will integrate it with grid power, the control logic has to prioritise self-consumption while still allowing programmed export limits. Please base the topology on readily available power stages (e.g., SPWM full-bridge or LLC plus high-frequency transformer if you think that’s more efficient) and specify safety-certified components wherever possible. I am open to SiC or GaN devices if that improves thermal performance without driving costs beyond reason. Deliverables I expect: • Complete circuit schematic and functional block diagram • PCB layout files and ready-to-manufacture Gerbers • Detailed bill of materials with part numbers and sources • Firmware source or control algorithm flowchart for the DSP/MCU you recommend • Brief test plan outlining how I should verify efficiency, protections and grid-sync operation I will prototype locally, so clarity in documentation is crucial. If you have recent experience designing residential hybrid inverters or similar power-electronics projects, let me know the standards you designed to and the tools (Altium, KiCad, MATLAB/Simulink, etc.) you typically use.

Hi there, as an Electronics Engineer with deep expertise in power electronics specifically in the design and simulation of DC-DC converters (Buck, Boost, DAB) and bidirectional power flow.I am well-equipped to develop this residential-scale hybrid inverter for you. I have extensive experience using MATLAB/Simulink for control system modeling and Altium Designer for high-power PCB layouts. My previous work includes developing an AI-driven adaptive protection system for microgrids and a green hydrogen microgrid project involving a Dual Active Bridge (DAB) converter, where I focused on high-efficiency energy recovery and grid synchronization. For this 3–5 kW system, I propose a high-frequency isolated topology using an LLC resonant converter for the DC-DC stage to ensure maximum efficiency, coupled with an H-bridge SPWM inverter using SiC MOSFETs for superior thermal performance and reduced switching losses. I will design the control logic to prioritize self-consumption and battery health, ensuring full compliance with IEEE 1547 islanding protection standards. My approach integrates seamless switching between solar, battery, and grid inputs while maintaining a true sine-wave output.
