FoxESS Community - Owners & Installers Forum

Sharing for general awareness for people looking to use thrid part ev batteries with their fox inverter for advanced users only.

While watching a video by Cory Mac on his channel https://www.youtube.com/@corymac I noticed that while quoting a good source of canbus information from a discord server called Dala's EV I spotted Foxess-Inverter channel.
So I signed up to Dala's Patreon to access the discord server https://www.patreon.com/dala/posts and noticed a number of people had successfully got a fox inverter working with generic and EV batteries by using a BMS emulator.

Video in question

This is extremely good...

Would it be "wrong" to pour some of that knowledge in here?

If anyone is interesting in writing their own BMS, some time ago I had a stab at documenting the Canbus protocol, and also the RS485 inter-pack protocol, it's early days and the battery pack range has expanded considerably since, but it's a start.

Not at all, this subforum for canbus stuff is what I had planned for this area of the forum. Feel free to use the space for the benefit of all fox owners.
