Hi, I've got a three year old 50A (really for 40A) kit using the C240 contactor and I think it has a v4 board.. I'd like to upgrade it to the Struthers & Dunn relay, and while I'm at it I'm going to add the wifi module.
Is there any reason I would need to upgrade to the v5 board to do this? Is there any advantage to swapping my board for the v5 board?
There is no reason to upgrade the v4 to v5. The major improvements the the v5 are the connector/harness which speeds up build time.
