Please also post a video of your whole set-up including the process of going through the pre-charge cycle and spot values changing. Please find video here: https://we.tl/t-M0ipMMB1EL Attached below you'll find the ignition and start spot values, as well as my current parameters. Ignition.jpeg Start...

Humour us and try with a charged 12v car battery for low voltage side and per Catphish upgrade to sine firmware v5.20r Edit: these are my parameters working with a base LDU and sine firmware 5.20r params.json I just updated the firmware to version 5.20r and inputted the parameters you shared. Still...

If it’s a car battery are you sure it’s fully charged?

I'm using a power supply

The correct mode is called "DcSwOn". This keeps the contactors closed during a fault, which sounds strange, but is the safest option for protecting your hardware. 1) Disconnect ALL high voltage cables from all contactors. 2) Temporarily set udcsw to zero to allow it to switch the contacto...

You should be using parameters designed for an LDU. These can be found at https://openinverter.org/parameters/view.html?id=16 In fact these ARE the parameters you appear to be using, but I was confused because in your post you said you were using the default parameters listed at https://openinverte...

First, before you do anything else, set tripmode=1 (Keep DC switch closed). Any other setting can cause serious damage to the inverter in the event that you hit an overcurrent error. How do I do this? I don't see an option for a numerical input. Do you mean to select the first option in the drop do...

You say you set the parameters to their defaults, but in the screenshots you seem to be using an LDU config. Did you apply the correct LDU config later? If you were running with defaults, that would explain why everything shut down when you started to apply throttle. Thanks for the thorough reply. ...

Okay. So you need to follow the wiring diagram on page one of this https://openinverter.org/forum/viewtopic.php?t=76 thread and most certainly wire-in the encoder. Otherwise you will damage it.

What does the last error say within the interface? Worth ensuring the contactors all work properly before connecting HV. Got a good picture or video of your set-up? Thanks for the reply! I just watched your "Beginner’s guide to spinning a Tesla Large Drive Unit for EV Conversions" on Yout...

Apologies in advance if I missed the answer to this somewhere in the forum. I have three TE EV200 contactors, an Arcol HS 100 watt / 33 ohm resistor, and a Mersen 600a 500v fuse making up the HV wiring. The ignition contactor A1 terminal is connected to the 378v battery negative terminal and the A2 ...

Thank you so much!

Hi there! I have a Tesla LDU Logic Board that shows "inverter8" on the Wifi list. The passwords "inverter" or "inverter123" don't work. I have misplaced my printed sheet with the unique password (and I'm kicking myself for it). Does anyone else have the password for &qu...

Hi there, did you find the password for inverter8?
