Quick update. The Rev 6 Nano Inverter controller software is coming along fine just a few more wrinkles to iron out. But I am nervous to place orders yet incase there are any hardware changes required to help make the software work as required.
I decided to create a separate PCB for the Variac it was about the same amount of work compared to creating the special build documentation from the Nano Rev6. And of course if either board needs an update it would affect both boards, so not the best plan.
I sent the Variac controller out for prototype manufacture today. Once confirmed that the prototype works it will be ready to order. It should be good for at least 2.5kW.
I will start a spreadsheet shortly to keep track of orders/requests, and I will post the list soon in a future update to this thread with the requests I have already received.
The Variac needs 4 boards in total, a controller board a FET driver/Capacitor board, a FET PCB plus a small serial LCD interface PCB. I will also throw in a current transformer with an order for the set of 4, which I expect will be less than $10 including delivery to you within Australia. For extra sets sent at the same time allow another ~$6. Final price will be determined by JLPCB & Delivery costs.
For overseas purchasers pm me for your pricing please - you wont be disappointed.
Just to clarify please dont send requests to order just yet. I expect in another 2 or 3 weeks max I will have proven the prototype and be ready to accept orders.
