This git is an opensource project. The orginal design comes from a bloke on Finders Island going by the handle of OZTULES. He has given the design to the public domain. I have simply penned the schematic down by reverse engineering his PCB as this was not written down anywhere. The files here contain the basic version and also a version coming with switchmode regulators. Free for anyone to use. 4/09/16 reworked with switchmode ps for 48-12v conversion. Changed pcb to 10x10. Use this type of regulator http://www.ebay.com.au/itm/DC-DC-Converter-4-5-60V-Adjustable-Step-Down-Buck-LM2596HV-Power-Supply-Module-/261942503087?hash=item3cfcfd66af:g:pZwAAOSw-7RVE8oj

Questions

How big is the Ozinverterkicad PCB?

It measures 99.8 × 99.8 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Ozinverterkicad use?

83 parts, built around the MCR100-8, IR2110L4, FR107 and TIP35C. 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 Ozinverterkicad KiCad files?

From the PawelSroczynski/enklava repository on GitHub, at the commit this page was made from: the board is hardware/ozinverter/modded/ozinverterkicad.kicad_pcb and its schematic hardware/libre_solar/bms-c1/kicad/bms-c1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Ozinverterkicad design in my own project?

Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
