    Dala's Leaf buildthread (2015 Nissan Leaf)

    Looking forward to follow this! I heard previously about CCS beeing so hard to reverse engineer, and as I understand it, it is using power line communication, which I guess does not make things easier. But I still find it strange that it can be that hard if you have access to both charger and...

    DIY 230v/2kw HV inverter

    What I've found about standard transformerless grid-tie inverters is that there are higher level of quality requirements on the PV side cables, also safety switches and over current protection seems to be convention or law. On EV's with HV batteries isolation tests between chassis <-> HV+ and...

    DIY 230v/2kw HV inverter

    Good point. Correct it's not isolated. Mainly what I want to try out is connecting it to an isolated battery setup from an electric car. Do you know how PE use to be handled in standard grid-tie inverters as they're usually transformer less and have a similar topology?

    DIY 230v/2kw HV inverter

    One step closer. Still have some components to order though. The large blue card is the power stage, the smaller blue is the logic board, the 4 larger green are different output filters and the small green is logic voltage supply.

    DIY 230v/2kw HV inverter

    Good point. Not sure but guess it is cause the challenge was initiated in US, even if 120v is more common at households, 230v is used at the low volt sections of the grid, right? But its a minor change I would say, the sine wave is not calculated on the fly but taken from a lookup table in this...

    DIY 230v/2kw HV inverter

    Hi. I just wanted to share this open source inverter project; https://github.com/jaw0/littlebox-power-inverter as I guess it could be of interest for some people here. This pic shows the size and layout; https://raw.githubusercontent.com/jaw0/littlebox-power-inverter/master/img/IMG_0724.JPG...
