nice, you just changed 9600 to 115200? no changes to the nextion display?

I changed both. Nextion display too.

So.... After I thought that my tesla charger works, now it shows fault on the 2 out of 3 inverers that I thought were running. They were only pushing about 1.8 amps and after about 2 hours I got "fault" error on the 2 working inverters.
I am looking now for a 3.3.or 6.6kw Chinese charger on Aliexpress.

This weekend if I have time I will try my 9mm tool and if that does not work I will move to the 308 tool. it is frustrating when you spent 700-800$ on this setup.
The boys are trained on all tools, but my daughter needs to start training on the 9mm.

hahahahah those are some drastic measures

Octavius convinced me to check again before I used my metric tool and found out that this AC switch went out.

Now it is charging with 4 amps I tried to go higher but the inverter contractors keep going on and off. for now is good because is a thin AC cable and it is only 120V.

at least I am finally charging the battery.

on 120v ac if you pull more than 10amps AC, the voltage drops so low that the charger resets itself, and tries again.

Always use the correct tools when working with HV
