Re: [RE-wrenches] Parts List For AC Couple Disconnect

Mark: I think the task is to measure battery voltage and, if it gets too high, generate a signal to disconnect the AC coupled feed to the AC bus. Therefore the sample is DC, not AC. Simple matter of voltage dividing into an acceptable range. I submit that there are probably a lot of ways to

Re: [RE-wrenches] Parts List For AC Couple Disconnect

Glenn, OK, while I would prefer to not get into compiling code onto an ARM, my main question would be, how do you get the voltage value into the Arduino? Rectify the AC voltage and then voltage divide down to the chip input pin? Mark On 11/2/2019 10:14 AM, Glenn Burt wrote: Sounds like a jo

[RE-wrenches] What type of solar racking?

I went to see an existing solar installation (in the Colorado Front Range) yesterday that was installed ~2008. It's still working well but homeowner is considering either adding another array or swapping out the 170w modules for something newer to increase his output. It's a very nicely done instal

[RE-wrenches] Parts List For AC Couple Disconnect

Folks, Can anyone share a parts list for setting up a AC couple disconnect? I want to couple a non-frequency response grid-tied inverter to a battery based stand-alone inverter. I have only 8 amps output from the GT inverters, so can use 10A relay contacts. I want a device to monitor AC vo
