Re: [RE-wrenches] IQ8: Envoy needed for California installations

Hi William, I am 100% sure that the IQ7 would work without a Gateway. I am nearly sure that the IQ8's will as well. I'll sometimes turn the solar on before the gateway is fully installed just to test the strings, and the microinverters do seem to wake up. I am not sure what California might have t

Re: [RE-wrenches] Outback radian inverter with FM 100 ground fault

It's fortunate that you have two charge controllers, which makes troubleshooting easier. If there is a solid ground fault, it should be easy to track down. Assuming that it is intermittent, you can start to do things like swap which PV input goes to which charge controller. Then see if the fault st

Re: [RE-wrenches] Portable Home Back-Ups

Hi Michael, I have also gotten some calls from people asking me to install equipment if they purchase it on their own. Specifically a few calls about the EcoFlow equipment. It sounds like it even has some of the required UL listings (I have not looked into it too closely). But I tell them to do it

Re: [RE-wrenches] PV watts question

If anything, I'd be surprised that a 1.2 ratio is better than a 1.0 ratio. Although, maybe the fact that an inverter is generally more efficient when loaded closer to its rating compensates for some of the clipping with a higher DC to AC ratio. On Mon, Jan 27, 2025, 4:04 PM Rebekah Hren via RE-wre

Re: [RE-wrenches] Seeking Advice on LG Solar Panel RMA Process

Hi Lou, I had to reach out to them recently about an AC module of theirs that stopped working. I did send the RMA form to so...@lgsupport.com. It took them 4 days to respond. Turns out they were able to reset it remotely to get it working again. I am attaching the RMA form that I have. And here i

Hi All, I have just gotten myself into a pickle and so am posting this both as a note/warning too all, as well as seeing if anyone has tried this. I installed a small system with a Sol-Ark 12k a few years ago. The customer recently asked us to add some more power. An 8k was more than enough, so w

Can you swap the strings in each inverter? Then you'll know whether the issue truly lies in the inverter or the array. Cheers, Dave On Sun, Apr 6, 2025, 1:35 PM Jason Szumlanski via RE-wrenches < re-wrenches@lists.re-wrenches.org> wrote: > I should mention that the other inverter also has three

Re: [RE-wrenches] Enphase PCS

Hi Mac, Enphase's Power Control System (PCS) based limiting lives inside the IQ gateway, not the system controller. So you can still implement this on a standard grid tie system without the System Controller. Every system should have a Gateway. Cheers, Dave On Thu, Apr 17, 2025 at 8:56 AM Mac Le

Re: [RE-wrenches] Midnite AIO Generator Functionality

Jason, Cant you just make the AGS turn on the generator before the inverter gets to the LBCO? Maybe this is more difficult if you do not have closed loop comms and the SOC drifts. I am just working through my first Midnite AIO setup now, so I cannot speak to the nuances of how it will work with tha
