Questions
How big is the MPPT Inverter PCB?
It measures 92 × 75.4 mm and has 4 copper layers, 1.6 mm thick.
What parts does the MPPT Inverter use?
61 parts, built around the TL062, FOD3182 and AO3400A. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the MPPT Inverter KiCad files?
From the DavidBojanovic08/Inverter repository on GitHub, at the commit this page was made from: the board is MPPT Petnica/Inverter Big PCB/MPPT Inverter.kicad_pcb and its schematic MPPT Petnica/Inverter Big PCB/MPPT Inverter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MPPT Inverter design in my own project?
Its repository states no licence, so its author keeps all rights: ask DavidBojanovic08 before reusing the design.
