Hi, I can help develop the production-ready engineering package for your 5 kW grid-tied solar micro-inverter with 8 independent MPPT inputs, battery-ready provisions, firmware logic, protection, and remote monitoring. The best solution is to first review the existing concept, PV input range, grid standard target, battery requirement, thermal limits, enclosure size, and monitoring interface. I’ll then define the power topology, MPPT channel architecture, control MCU/DSP, gate drivers, sensing circuits, protections, communications, and PCB stack-up before moving into schematic, layout, and firmware structure. I’m comfortable with power electronics, MPPT control, inverter power stages, STM32/DSP control, gate drivers, isolated sensing, anti-islanding logic, battery charge control, Wi-Fi/Ethernet/RS-485 monitoring, multilayer PCB layout, thermal design, Altium/KiCad, and firmware documentation. Deliverables will include: * Complete schematic design * 8-channel MPPT architecture * Power stage and protection circuits * Multilayer PCB layout * Gerber, drill, and PnP files * BOM and assembly outputs * Firmware source/compiled files * Remote monitoring data interface * Thermal and design notes * Manufacturing handover package I’ll focus on a safe, manufacturable design path with clear provisions for certification, grid-compliance testing, and future battery integration.

Hello, I hope you're having a great day. I have hands-on experience having delivered multiple power-electronics and embedded-control projects that match your microinverter needs. I built a 3.6 kW microinverter with four independent MPPT channels, using an STM32 MCU for control and synchronous buck-boost stages with SiC MOSFETs to solve thermal hotspots. I'd start with a topology review (isolated full-bridge per MPPT or shared DC bus), schematic in Altium, PCB with thermal vias and split planes, firmware in STM32CubeIDE with FreeRTOS, and RS-485/Ethernet for monitoring (ESP32 optional for Wi‑Fi). If you have ten minutes, I'd like to compare notes on the preferred comms interface and the thermal envelope so I can lock the PCB outline. Thank you, habib Niazi
