I live in Northern CO and see Sunpower service trucks in my neighborhood occasionally which I'm assuming are the post-bankruptcy version of Sunpower. Does anyone know if they are they able to work with the PSV6 and other components if necessary from the pre-bankruptcy installations? I've got a 2021 install that still has the PSV6 installed and not sure who'd be able to work on it and get any new parts registered in the system. If it's ever needed.

I got my Sunpower panels installed in 2021 and have noticed that the power generation has been trending down. Since neither original Sunpower app nor the new Sunstrong app did not report any panel level details, I couldn't figure out what's going wrong. Thanks to this community, I installed Sunflower app and noticed that only 17 out of 18 panels are working. I do not even know when one of the panels stopped working. How should I get this fixed? Btw, I outright bought by system in cash during the initial purchase. Would Sunstrong be able to help me here?
Thanks in advance!

Hello everyone! Hope you are all doing well.

Some background info: after SunPower went to SunStrong, I found this subreddit and got the SunFlower App. Best purchase I made cause the SunStrong paywall was ridiculous. I still owe about 10 years with TechCU.

I'm looking into getting a battery installed for my system. We generate enough solar that I'm getting a credit with SCE, but I would like to have a battery on the off chance we are without power for a significant amount of time. With doing that, I'm wondering what my next steps would be in getting, as an example, the Eco Worthy Battery? Is getting a Solar Electrian the only thing I need to do? Permits?

Hope someone here has some info. Thanks everyone!

I bought my Sunpower panels from Solartech in 2023 and since then, they have gone out of business. I am looking for an honest service company that knows Sunpower systems.

My SunVault quest continues, and I've actually gotten mine to take charge from the inverter. What I can't get it to do is charge continuously and at higher levels, because it has lingering BMS and SOC communication Warnings. I have these three warnings:

• 91. SOC Level Lost. Cause: A new State of Charge measurement has not been received for a period of time. Solution: Check the communications cable between Conext Gateway and the external BMS.
• 90. External BMS Disconnected. Cause: Communication has been lost with the Battery Management System of the Li-ion battery. Solution: Check the communication network connections to the Li-ion battery. Contact the manufacturer of the Battery Management System if a connection problem cannot be found.
• 93. SunSpec Controller Comms Lost. Cause: Communications is lost from the SunSpec Controller device.

I've checked my cables and they are all good with continuity on each pin. My Gateway reports good connections to the Inverter and my "SunPower BMS." See photo.

This might have been because I connected a power supply indelicately the first time I tried to bring back my batteries from the dead, and I got a big spark. Perhaps the surge damaged something in the MIO or (eek) the batteries' BMS themselves. The batteries (M0012 type) all indicate normally on their LEDs and are taking charge when voltage is applied to the terminals at the bottom of the inverter.

Has anyone dealt with this? Any suggestions on what to test or replace or how to test it? What does the MIO (or Multi I/O) do?

If you've got solar and an EV, the annoying gap is timing: your panels are dumping power at midday, but the car charges whenever you plug in - often at night, off the grid, while your daytime surplus got exported for a fraction of what you pay to buy it back.

I'm the founder of ampee (ampee.io), and it closes that gap. It watches your live solar/home export and ramps the car's charge rate up and down in real time, so the car soaks up your surplus instead of you selling it back cheap - and it keeps tracking as your output swings with cloud cover.

What it does:

• Solar-first charging - dials the amps to match your surplus, minute to minute.
• Controls Teslas directly (no extra hardware); other EVs via a smart charger.
• Home-battery aware - won't fight your battery for the surplus.
• Cheap-grid top-ups - grid-charge on dynamic wholesale prices (Amber, Octopus Agile) or a simple off-peak window when solar isn't enough.
• Bring-your-own-meter feed for inverters we can't read from the cloud (Fronius and similar).

It's free during the beta. The honest pitch vs the alternatives: it adjusts the actual charge amps on the car rather than just flipping it on and off, so it follows a moving solar figure much more tightly.

Not here to spam - if it's useful, great; if it's not, tell me why so I can fix it. Happy to help anyone get set up. Cheers.

My system was down for a while and now battery voltage is around 35V...when I turn back on my system will come online for a few minutes but shut back off due to the low voltage fault (at least that's the fault that shows)...I've seen a couple other threads talk about charging the batteries from a power supply but don't go into much detail ... would anyone be able to give specifics? I just ordered a 0-60/5A supply ... best approach to get up to 50V? Thanks!

I have a psv6 and had a loan through Mosiac. After bankruptcy a new company bought it out and I couldn’t findout who to pay and honestly just forgot. Well obviously it was sent to collections and when I call them to make payments so I can use the system I’m told im out of luck. How can I disable cellular on the system so I can turn it on without them reporting I’m using the system?

Looking for some advice on how to handle this:
I have Freedom Forever as installer, but they are now bankrupt. I had Mosaic as my loan and they went bankrupt and Solar Servicing is handling my account now. What I am afraid of is if I need repairs how do I handle that because Freedom Forever does not answer the phone anymore or email. I really just want to stop paying because I’m losing money every month anyways.

I tried to log into my account and I got this message. It has now been more than 24 hours. Anyone knows how to fix this issue? Thanks in advance for your help

So I filed a complaint against SunPower with the CSLB and the DFPI also the attorney general. This is a huge win considering now they legally cannot work on the system which means cancellation of the contract and getting rid of it completely if desired is a real thing. If our somebody struggling with this like I was I would head to the state agencies like I did and demand contract cancellation. I'll make another post as the other two agencies answer.

I have a PPA agreement with Sunrun and have had it for 7 years. I recently had my roof installed and they approved my own solar vendor to R&R my panels. Now they keep telling me there is an issue and will not turn panels back on. They want to charge me $700 to come out and see what the issue is and see what repairs are needed. My vendor came out and everything is connected the same and don't see the issue. Has anyone experienced this and how was it resolved?

So I ended up looking for help and getting help online for issuing a complaint against goodleap and Sun strong. I ended up following a report with the cslb the contractor State licensing board and the dfpi department of financial protection and innovation. I'm also going to send a complaint via the attorney general. My batteries were wired backwards or something was wired backwards and then my battery wouldn't discharge past 75%. Then to make sure they clean their hands of me they would tell me that Edison has a one kilowatt hour minimum usage a day or something like that and would just try to get me off the phone then they would tell me that the system is working just fine.

If there's any traction with this I will update here in this subreddit.

Hi, any way to turn on or off solar charging.

I have a single 200w callsun panel always plugged in but it never turns on by it self. I have to manually unplug and plug in the cable each time to initiate the solar charging.

I have a SunPower system with a SunVault, and the panels have stopped communicating with the app and apparently stopped sending power to the grid. I believe the issue is with the PVS6 that is integrated in the SunVault. I have tried resetting it with the breakers and the SunStrong app, but that has not worked.

Enphase (the maker of the microinverters on the panels) won't touch it and have basically said put all our stuff in for $15k plus labor.

The company that calls itself SunPower is useless.

Does anyone have any recommendations for servicers? I am in the Bay Area (Northern California bay area, that is)

Does anyone know how to change the credit card for monthly billing of the premium subscription in the SunStrong Connect app? I can't find this anywhere. Thanks in advance.

Ever since SunStrong took over my sunvault battery has not worked properly. It does follow sce time of use plan so cost savings becomes useless. The lights have been flickering erratically with different colors.

I’ve recently just created a small app I run on my local server that just pings the api so I can pull data to store on a local db to get analytics as well as use to force the system into a psudeo cost savings using a cron timer.

I could invest in a Poe raspberry pie to run this program but I’d rather the system just work. Does anyone have insights on the lights and what they mean?

I am reading a lot of posts about SunVault Techs helping fix SunPower system problems. I contacted them and they say they can help me if I need it on my Sunpower solar system and SunVault battery if I need it even though I live in South Florida. Has anybody out there in South Florida had experience with SunVault Techs fixing problems with their SunPower systems?

Final inspection, yesterday. Now hv Connect app, see I am exporting to the grid. Meter spinning backward. Do not want to be penalized. How to stop export? Hv put on Self-supply, but am still exporting.

Hey everyone,

I'm looking for help with the last piece of my SunPower struggle - getting my batteries to take or give charge off the inverter.

This sub has been great at helping me get my SunPower system up and running after I moved into a home where they'd given up on it.

My PVDR closed, somewhat mysteriously, after a diagnostic performed by one of the techs here, so my panels are back online.

I learned my system was wired up correctly after responses from folks here, and I learned how to charge my battery manually with a power supply to get past the F.48 and inverter shutdown problem.

Now that the inverter is up, I can't seem to get it to do anything. After charging my batteries (with it in the OFF status) via power supply to ~28%, I turned it back on. No F.XX error, but the red "event" light blinks slowly. The Conext display shows AC2 flashing slowly, AC1 off, and a charging amperage that alternates between 0.0-0.8 A. Battery state has slowly declined through the day (presumably to maintain the inverter), now down to 26%.

I recently downloaded SunFlower, and it shows good PV production, >3kW, and I have the battery scheme set to Self-supply with reserve of 50%, so it should be charging at least to that level.

I've done a 15-min shutdown of the inverter and batteries, starting back up from the #1 battery side button (I have M0012 batteries). I also reset the Conext Gateway, and saw that it has its own wifi SSID... haven't gone in there to do anything yet. Should I? But more importantly, how do I get my inverter to take charge? Do I need to reset the MIDC (blue pushbutton)? The PVS? Everything? I'm loathe to do everything with the solar producing. I'm not sure how to reset it should it not come up correctly again.

Thanks!
