Re: [RE-wrenches] Charging a Bolt with an SW
I had a Nissan Leaf and a 240v charger, we had no problem using our Radian to charge it during the day.

Re: [RE-wrenches] Charging a Bolt with an SW
The old SW waveform changes with battery voltage. On the 24 volt version there are less steps when the battery is over 28 volts. My washing machine motor does not run when the battery is over 28. I just have to turn on the microwave when I want to do laundry on a sunny day.

Re: [RE-wrenches] Charging a Bolt with an SW
I’ve got offgrid 2 clients and they have no issues. They each have a Bolt and can choose the charging rate. They can run it at either power. But only use higher power when they have lots of sun. Older Stacked vfx and Schneider xw, no issues. I would expect the SW to work, however it’s an odd beast as it’s waveform steps change with load. More load, more steps, therefor cleaner so maybe at lower charge rate it’s not clean enough. As to your issue it could be power factor Being really poor. Can you tell us what inverter, yea 5 years ago is a long time.

Re: [RE-wrenches] Charging a Bolt with an SW
I think you said it well, about 5 years ago I tried to charge a car from an off-grid system. I did not record my events but the inverter had twice the power of the level two charger, yet the inverter would get hot and trip out. I was told a ferroresonant transformer may help, and it might be different with different cars. However, I was warned the ferroresonant was to stop input wave problems from arriving at the output not to prevent the output wave problems showing up on the input. The off-grid customer gave up.

Re: [RE-wrenches] Outback question
You think it is interesting? I hate problems like this. You are doing the right thing in my opinion. Disconnect the network and try to duplicate. This is a troubleshoot halfsplit to an engineer/technician, or you and me The other choice at this point would be a complete DC disconnect for as long as it takes to get the DC system wide to below 2vdc. Your question on programming? Did someone/something put the CC into float only mode? I had a customer who did weird things and I set-up logging on an SD card and it recorded system changes. He paid me a bit of money for me to prove he was the problem. Nice and cool! Gonna play "highway to hell" and wack the weeds.
