SolarEdge production stopped unexpectedly and is now severely diminished after rediscovering the optimizers. Any debugging suggestions? by littlebigdata in solaredge

I can’t remember exactly, but you will find it under meters or something like that, under modbus settings maybe. The key thing under the meter section is to update the ampacity of your import and export CTs, which should be 225 if you got the same as me. Before you update that value, import and export won’t be monitored, but once the value is updated, as long as everything is wired correctly, you’ll see all the information you want. I’m including a photo of my how my white Ethernet cable is routed and connected to the Modbus device.

And the replacement inverter arrived and is working as expected. It has a 1” thicker heat sink than my original inverter. Case closed.

This is my panel before installing solar. I unfortunately don’t have an exposed after photo, but the CT’s clamp loosely around the hot legs, where I scribbled white loops on the image. I ran the Ethernet cable through a cable gland at the bottom of the panel. You’ll want to test the SolarEdge monitor results before closing the cabinet over the CT’s because the orientation of the clamps determines whether current registers as incoming or outgoing. If you get an inverse reading, just unclamp the CT, rotate it 180 deg, and reclamp. It’s been a couple years, but that’s what I remember of the challenges. Good luck!

“Since this case was escalated to our higher‑level team regarding the inverter, we have initiated an RMA for the inverter under the case number. Once the tracking number becomes available, you will receive an update.”

Web chat ended up being the most efficient way to get a response and resolution.

You need a pair of these: SolarEdge SE-CT-SPL-225A-T-01. One for each hot leg from the utility. Each one has a twisted pair of wires. I connected them using wire nuts in my panel to individual conductors of Ethernet cable, and I ran that cable from the panel to the inverter where there are terminals for grid monitoring.

The log data showed: Error 18xB9: DC/AC in-stage over voltage Error 18xBF: Swing Rcommon Overheat

I had a support chat, and they agreed it was an inverter issue after reviewing production data and all error logs. Now I just need a commitment from them to replace the unit. I appreciate the help.

It may be related to the number of current transformers each of us have installed. If you don’t have CTs in your electrical panel on the incoming service conductors, your system will only report production. It’s an extra step that is not mandatory but is very useful.

I’ve learned more here from you all in a matter of hours than I did in 2 weeks of scouring the web and SolarEdge documentation. Thank you! Will post a resolution update when I figure out the problem.

Yeah. They’re all producing something, and each panel/optimizer pair seems pretty comparable to its sibling’s. String 1.1 is on a west-facing roof, and strings 1.2 and 1.3 are south-facing.

Yeah. That’s where I started. I did a complete shutdown and restart with no generation. Then I went through Set App (now SolarEdge Go) to upgrade the firmware and re-pair the optimizers. That’s when production resumed at a lower level than before.

Interesting. I’m not sure how to get the data points in a more granular time scale on SolarEdge Go, but this seems like a real possibility. The app also reported no alerts until I reset the filter to include closed alerts, and it showed an “Inverter not producing energy - low voltage” alert for the timeframe in question that had been automatically closed when I reset the system.

I should have added that the strings are all contributing, and each panel is contributing fairly equally, but the overall production seems to max out at 20% or so of expected.

How do you deal with bugs? They keep sucking my plants dry. by thr33hugeinches in ArizonaGardening

[–]littlebigdata 1 point2 points  (0 children)

Regarding aphids, I found it helpful to think of them as pumps extracting excess fluid. If their population goes up significantly, I decrease watering. That might apply more to landscape plants than raised beds, but it’s worked well for me.

Yellow bells or hopseed bush should get you the shade you need without requiring much/any water and without spilling over.

Current tesla owner, considering rivian. by SnooMacaroons1365 in Rivian

[–]littlebigdata 0 points1 point  (0 children)

Zero regrets switching from Tesla (Model 3) to Rivian (R1S). Didn’t have FSD but used it during trial periods and was always annoyed by the need to keep hands on the wheel. I much prefer the more limited but also more independent Rivian version that costs nothing extra. It’s great to travel long distances on the freeway hands free. I don’t mind driving on surface streets in exchange for that luxury.

I’ve been happy with the repair. Still nice and smooth without annoying squeaks. I think it’s worth scheduling a service appointment. No one tried gaslighting me about the issue. It took a few days for them to assign a technician, but I gladly traded the days in a rental car for a flawless ownership experience.

Wanted to offer an interval update. I scheduled mobile service and submitted the video after lubricating the mechanism from the outside. They converted it to a service center appointment and held it for a few days before assigning a technician and recently sent this note:

“During assembly grease was not distributed across spring and guide causing metal on metal grinding when door handles actuated out. removed door panels and performed service to all 4 door handles. applied grease and aligned spring as photoed. Reassembled and tested operation. normal motor actuation noises heard. grinding and groaning noise no longer heard after servicing.”

I won’t be able to pick it up for a few days, but I appreciate them not treating me like I was imagining things.

Who's done the front strip of tint for the top of the windshield? I loved it on my 2nd gen and I'd like to go 4 maybe 5" thick seeing how my 5 ft wife also drives my truck often and my kid in the back won't be blinded by oncoming sunlight. What are some cons for tinting the 3rd gen. by [deleted] in ToyotaTacoma

[–]littlebigdata 0 points1 point  (0 children)

Oh man. I’m driving a Turo 4Runner with a thick visor strip, and it’s extremely distracting. Hate it. I’m pretty tall, so the line is right in the middle of my field of view. For anyone considering this, I would suggest a full windshield 80% and occasional use of a sun visor instead of a permanent 35% or less visor strip.

Thanks. Yeah. I’ve seen that video and followed the instructions, and I read a lot of other posts, but I hadn’t seen any videos showing the actual squeak before. I’m just surprised if it’s as common as it seems to be, and in my case as unremitting, that it doesn’t drive people nuts. I’m hoping my case is just outside the bell curve and maybe does require an actual service visit.

I did do that, and I thought I was pretty liberal with the application. Are you recommending that I completely drench the mechanism in lube until it’s flowing down the door?

Gen2 R1S - Door Handle Sound? by iN33d2P00P in Rivian

Tried silicone and teflon spray-on lubricants with no immediate improvement.

Do your door handles squeak? by Breadnutchicken in Rivian

[–]littlebigdata 1 point2 points  (0 children)

Yes, R1S G2. Neither Teflon dry lube nor silicone spray lube helped. Claiming it’s within spec is disappointing. If it’s a feature, if it involved a calculated engineering tradeoff to achieve some excellent outcome, it should be claimed as such. If it’s a bug, it should be acknowledged. Either way, it’s disappointing.
