The SunPower web portal shut down — where did it go?

What happened to it

The portal wasn't relocated and there's no new address to bookmark. SunPower filed for Chapter 11 bankruptcy in 2024, and on September 20, 2024 all official support was shut down — the customer web portal, the mySunPower app, and the 1-800-SUNPOWER line, together. Roughly 600,000 residential systems were affected.

SunStrong Management subsequently took over the monitoring platform, primarily serving lease and PPA customers, and rebuilt the app as freemium: a free "Basic" tier with real-time power flow and system health, and Premium at about $9.99/mo for history, panel-level data, and analytics.

The part that stings: your history

Production history that lived only in SunPower's cloud generally went with the cloud. There's no honest way to soften that. It matters more than people expect, for two reasons:

• Degradation. Panels lose a small amount of output each year, and the only way to know whether yours are ageing normally is to compare like-for-like against previous years.
• Resale and warranty. A documented production record is what supports a warranty claim or reassures a buyer that the system on the roof actually performs.

Whatever you choose next, its history starts the day you connect it. That's the one argument for not leaving this for another six months.

Getting a view back

Your gateway — the PVS6 near your electrical panel — never stopped collecting data. It reports locally on your own network, which is why independent monitoring is possible at all. Three routes, in ascending order of convenience:

1. SunStrong's app. The official continuation. Free tier for a basic view; Premium at about $9.99/mo for history and panel detail.
2. Pay Enphase to replace the gateway. A technician comes out and swaps the SunPower gateway for an Enphase one. Most hands-off, most expensive — $999 as of August 2026; confirm with Enphase. Not available for SunVault battery systems, which Enphase's monitoring-restoration service explicitly excludes.
3. Plug in your own monitor. Keep the gateway you own and add a small box that reads it on your network — no technician, no appointment. (If you're technical, free open-source projects do the same thing if you're willing to run and maintain them.)

Don't forget the warranties

While you're sorting monitoring out, this is the moment to check equipment coverage — the company warranty is gone, but the manufacturers' warranties survive and are claimed separately. Enphase covers microinverter parts but no longer labor. Maxeon honors panel warranties but required self-registration by December 31, 2024. Qcells, Fronius, REC, and Fimer are equipment-only, excluding labor and shipping. Start by finding your original contract and identifying who made what.

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 $50 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.

Common questions

When did the SunPower web portal shut down?

September 20, 2024. SunPower shut down its support operations that day, taking the customer web portal, the mySunPower app, and the 1-800-SUNPOWER phone line offline together, following its Chapter 11 bankruptcy filing earlier in 2024.

What replaced the SunPower web portal?

SunStrong Management took over the monitoring platform and rebuilt the app on a freemium basis, with a free Basic tier and a paid Premium tier. Its focus is primarily lease and PPA customers. Owners who bought their systems outright often find independent local monitoring a better fit.

Can I get my old production history back?

In most cases, no. Historical data that lived only in SunPower's cloud went with it. Any new monitoring starts building history from the day you connect it, which is a good reason not to put it off.

Do you support the PVS5, or only the PVS6?

The monitor reads your gateway's local interface, and the PVS5 exposes the same one — so it was built to work with both. What we can't tell you yet is that it's confirmed, because we haven't had a PVS5 to test on. That testing is open now: if you have a PVS5 and want in, email tony@watthacker.com and you can be one of the units we verify it against.
