Solax X3 PV3 and BAT2 #87

Open rgrae81 opened 1 week ago

rgrae81 commented 1 week ago

As I had a look at the Solax X3 Programming i found that here is no PV3 and BAT2 I have a X3 Ultra 25k with 3PV Strings and 2 BMS connected.

Would it be possible to add PV3 and BAT2?

Hi, Yes, of course, it’s no problem. But I cannot do it by myself, please do it by yourself and after it I want add your new registers.

please look into the wiki to get instructions for doing that

OK, so for Growatt it's 2+3 but for Solax the same? Seems like it will be for Solax 2+1

Ok, there are the Solax Modbus Register Documents, I have already a newer one, but it don't explain to me how to calculate the position for Solax, or is header +3 for all devices ?

Yes - you are right, please look into the wiki page ;)
