The bare board was $60 and the components were about $200.Nice. Do you have a ballpark price of expenses so far? What is your electronics experience level? Thanks for starting this thread.
I am trying to decide whether to buy tested populated board or go DIY.
Paul had his whole life stolen (was moving and the moving truck was stolen with all his things).Are the Paul holmes leaf inverters still available? It seems that the website is no longer operational.
Wow...I have no idea how to do any of that, but I really appreciate the information. It looks like I have even more research to do. I'm beginning to feel like I've bitten off a bit more than I can chew.Paul had his whole life stolen (was moving and the moving truck was stolen with all his things).
I think I heard somewhere that he wasn't much interested in doing inverters for people anymore.
The new meta for cheap DIY EVs is to buy a Prius Gen 2, Gen 3, Lexus GS450H, Nissan Leaf, maybe some other Toyota model inverters, then a controller to hijack them, and use those.
Guys are finding Gen 2 and Gen 3 Prius controllers for like $40. The Gen 3 can handle about 680 horsepower. More than anyone needs. They also have a built-in DC-DC 12v converter, one of the motor controllers can be repurposed as a charger (software is being written right now), and an A/C inverter too. Bulletproof and they soft fail when you overheat, abuse, or tell them to do something stupid.
You can buy Johannes' inverter controllers for around $500 (380 euro) on OpenInverter.org (also forums there). Or Damien's for around the same price on EVBMW.com.
Damien used to offer even cheaper ones but we are frustrating and fickle to deal with, so I think prices go up to make it worth his time and make sure he's not losing money. For example a Gen 2 board used to be $30 and you could flesh it out with components for $70. Plus a few extras needed, easily under $50. Meaning you could have a 500+HP inverter with custom controller for under $200 in many cases.
My advice is worth less than you've already paid for it.Hey Matt, do you offer tutorials?
If you fly to New Ireland Electric (in Ireland), they host monthy DIY EV workshops for $1000 for the weekend. I'm not sure how many they're still doing with Covid now.If you offer a class or private instructionals of some sort I would love to take part. I understand my shortcomings and need a pros guidance
I do still have my board (and stuff to populate it, but I never did get to it). I ended up buying a Scott Drive SD300 so I'm not going to use this board.Are the Paul holmes leaf inverters still available? It seems that the website is no longer operational.
