Solax X3 Ultra

HI

I am looking at a Solax X3 Ultra 30k Inverter, but i don’t find much about compatible Batteries/BMS.

In some forum i found mentiond that they used pylontech protocol but then changed it.

“EmanuelFAU” built a " solax_can_fake" which “change the can watchdogmessage (0x1877), which includes the battery manufacturer code. Whith this, any sutable battery can be used with the solax x3 hybrid G4”.

I don’t know if the X3 Ultra is the same.

Could DIY BMS change this byte too? Should I risk buying this inverter too use with a DIY BMS?

Thanks Chris

If you get the Solax X3 Ultra, I will support the implementation. Should be not much of an issue if there is a working can faker.

Thank you, but the can faker is for another inverter (same manufacturer but different family).
So i am not confident it would work and i can’t afford to buy it on a whim.
Sorry for the late answer. I haven’t decided yet.
