With a RS485 cable connected to the Pi and a monitoring software like SolPipLog or SolarAssistant, or direct commands to the inverter for read-outs.

I haven't been around for a while, good to see many extra features now with TWC Manager. I am wondering if someone could help me make it run with a Voltronic solar inverter. I am in a off-grid scenario, and would like to have the TWCManager change the amps to the car depending on the battery...

Thanks for your replies :) It is not a problem. We have been charging like this for half a year now. First on with a 'Granny' cable on a fixed 10A or 13A. The voltage drop is caused by the fact that the amount of Amps are fixed and, as we didn't connect batteries a buffer but are directly doing...

@CDragon hahaha, I misspelled your name in the previous post. As I don't see an option to edit, this is the 3rd post in a row ;-) Something strange I noticed: When I up the Amps through the webpage (I edited it to be able to change amps by 1A from 6-20A), when I for example change the amps from...

@cdragen: I tried to print the Voltage on the index.php, but couldn't figure out how. I used $voltsPhaseA, but that doesn't give anything. How could I do this in the py script: if the voltage => 240V add 1A if the voltage =< 200V substract 1A

Nice project! I followed the TCWManager pdf but it script wasn't autostarting from rc.local: it didn't show up in screen -r. I chmod ~/TWC/TWCManager.py to 744 to make it executable and now everything works fine. I have a off-grid project: ~6000W of solar panels connected to a 1 fase inverter...
