Power Electronics & Battery Management (BMS) Jobs

I am looking for an experienced power electronics engineer or engineering team to design a residential-scale hybrid solar inverter for commercial production. The project involves developing a single-phase, 230 V AC, 50 Hz pure sine-wave hybrid inverter that integrates rooftop solar panels, a lithium battery bank and the utility grid. The design should prioritise high efficiency, reliability, safety and ease of manufacturing. I prefer an engineer with previous experience designing working solar inverters, grid-connected converters, MPPT controllers and bidirectional battery systems. An existing, validated reference design that can be licensed or transferred is preferred. 1. Target Specifications Rated power: 1–5 kW continuous AC output: 230 V RMS, single phase, 50 Hz Output wave...

I need a complete electrical design for a true-online 600 W UPS that will operate in a home environment. The scope covers everything from the high-level architecture down to production-ready documentation, so that I can have the unit prototyped and assembled without further engineering work. What I expect you to produce includes: • Full schematic with clearly annotated component values • Bill of materials using readily available parts • PCB layout files (Gerber or equivalent) and 3-D board view • Control logic or firmware source (if a microcontroller or DSP is used) • Mechanical outline showing heat-sink placement, transformer or inductor dimensions, and suggested enclosure size • Brief test plan describing how to verify continuous 600 W output, transfer time...
