First: make sure you are contacting the right half of the company
SunStrong runs two separate systems with two separate accounts, and a message sent to the wrong one lands with the wrong team. Billing, payments, statements and 1098 forms live in SunStrong Consumer Central (esp.myaccountinfo.com). Solar production lives in the SunStrong Connect app. We wrote that up in detail: which SunStrong login you actually need.
For anything else, their Help Center is the front door, and the portal has a Contact Us form once you are signed in.
⚠️ We deliberately do not reprint a phone number. SunStrong does not publish one in their page source, and passing on a number we cannot verify — on a page whose entire promise is helping you get through — would be worse than saying nothing.
Why it is like this, which is not an excuse but is an explanation
SunStrong absorbed the customers of two bankrupt companies inside a year: SunPower's lease and servicing portfolio after its 2024 Chapter 11, then the legacy Sunnova portfolio in September 2025. It now says it manages more than 500,000 customers.
Owners describe the result plainly. Holds of one to two hours during the changeover. Portal accounts that would not create. Messages that bounced. One owner wrote that an agent told them the company was taking thousands of calls a day. ⚠️ Those are customer accounts from a public forum, not figures we can verify — but there are a lot of them, and they are consistent.
If support does not respond, these places exist
Stated as fact, not as advice — what you do is your call, and we are not your advisor:
- the Better Business Bureau;
- your state Attorney General's consumer protection division;
- your state public utilities commission;
- the Consumer Financial Protection Bureau, for billing and loan-servicing problems.
For context on scale: on 17 March 2026 the Connecticut Attorney General announced an investigation into SunStrong Management LLC, after his office and the state Department of Consumer Protection jointly received approximately 65 complaints. ⚠️ An investigation is a request for records — not a lawsuit, not a judgment, and not a finding of wrongdoing. SunStrong has not been found liable for anything and is entitled to answer. Read the announcement itself rather than take our word for it.
⚠️ Whatever route you take, every one of them works better with dated production records. "My system has been down" is an assertion; a month of readings showing zero is a record.
And the thing that annoys people most
Underneath the hold times is a simpler grievance, and it is the one owners raise most: you already bought the equipment. The panels, the microinverters and the gateway on your roof are yours, outright, often for tens of thousands of dollars. Being billed a monthly fee to look at what they are doing feels different from being billed for electricity — and owners say so. One put it as paying *"to be allowed to enforce my warranty policy on something I will have covered for the next 26 years."*
The part worth knowing is that SunStrong is not the source of that data — your gateway is. The PVS6 in your garage measures your production and stores it locally, on your own home network. Any app is a window onto it. Which means the answer to "I can't reach them and I can't see my system" is not only a support queue.
If you lease your panels
Do not buy anything to solve this. Lease and PPA customers get SunStrong's paid monitoring tier included, and SunStrong remains your service contact for the system itself — a slow queue is still the right queue. You do not need our monitor. We would rather say that here than take the order.
If you own your system outright
Then you can stop depending on their queue for visibility, today. A plug-in monitor reads your existing PVS6 on your own network — no technician, no appointment, and no account anyone can suspend. With the WattHacker monitor, seeing your panel data is free forever: every panel, live, no subscription and no card on file. $99 once, then nothing.
It also keeps the record. Every reading, dated, exportable — the thing that turns "it has been down for weeks" into something you can hand to someone. ⚠️ To be clear about what that is and is not: we gather the evidence, we do not file or advise on your claim. We are not a party to your warranty and have never seen your contract.
And if you are technical, you can read the gateway yourself for free with open-source software, at the cost of setting it up and maintaining it.
Where WattHacker fits
The WattHacker monitor is a small box that plugs into your existing SunPower PVS6 gateway on your own home network and reads it directly. It doesn't rely on SunPower's or SunStrong's servers, because for owners like you those are either gone or behind a paywall. No technician, no electrician, no rewiring — you plug it in yourself.
- The monitor is $99 once, with a 30-day money-back guarantee.
- Free to see your panel data, forever — every panel, live, no subscription and no card on file.
- An optional premium plan at $6/mo (billed annually) adds the memory: full history kept for good, year-over-year comparison, and alerts told to you in dollars.
- Built by an electrification superfan who wants to help others use their solar smarter, lower their utility bills, and clean up the planet. Who's behind it.
Real panels, real production, no signup.
Common questions
How do I contact SunStrong?
Through their Help Center at sunstrongmanagement.com, and through the Contact Us form inside the customer portal once you are signed in. We deliberately do not reprint their phone number here — SunStrong does not publish one in the page source, and a wrong number on a page like this is worse than none. Use their own Help Center, which is theirs to keep current.
Why is the wait so long?
Scale, most likely. SunStrong took on SunPower's lease and servicing portfolio after its 2024 bankruptcy, then the legacy Sunnova portfolio in September 2025, and now says it manages more than 500,000 customers. Owners on r/solar report holds of one to two hours during the changeover period, and one wrote that an agent told them the company was receiving thousands of calls a day. That is a customer report, not something we can verify.
I am emailing them and nothing comes back. Is that normal?
Several owners report the same, including bounced messages and being unable to create a portal account at all. Note there are two separate SunStrong systems — billing and monitoring — with separate logins, and a message sent into the wrong one goes to the wrong team.
Where can I complain if support does not respond?
Public complaint venues exist and are free to use: the Better Business Bureau, your state Attorney General's consumer protection division, your state public utilities commission, and the Consumer Financial Protection Bureau for billing and loan servicing. Connecticut's Attorney General opened an investigation into SunStrong Management in March 2026 after his office and the state consumer protection department received approximately 65 complaints. We are stating that these bodies exist, not advising you to use them — that is your call, and we are not your advisor.
Can you contact SunStrong for me?
No. We are not affiliated with SunStrong, we cannot reset an account, open a ticket or chase a repair on your behalf, and we would not pretend otherwise. What we can do is make sure you have your own production data, which is yours regardless of who answers the phone.
