Your monitoring data does not belong to your Solar Partner. It lives on the inverter manufacturer's servers, and you can claim direct access in an afternoon. Even if the branded app you have been using disappears tomorrow, the underlying production history sits on Enphase, SolarEdge, SMA, Fronius, or Generac infrastructure waiting for you to register. This guide walks through how to do that on each major platform.
Identify which inverter you have before anything else
The inverter brand determines which portal holds your data, so start there. Look at the equipment on your wall and under your panels. Enphase microinverters are small boxes tucked beneath each individual panel, paired with a white gateway called an Envoy near your electrical panel. SolarEdge uses rectangular optimizers under each panel plus one larger wall-mounted inverter. SMA, Fronius, and other string inverters are a single box, usually within ten feet of your main service panel.
If you cannot tell from looking, the brand and model are listed on your installation contract, your building permit, or any system-overview sheet your Solar Partner left behind. Take a clear photo of the manufacturer's label on the unit itself — it shows the serial number you will need to claim the account. Write that serial down somewhere outside the installer's app, because if their portal is shut off you may not be able to retrieve it later.
How to claim an Enphase Enlighten account
Enphase has the most homeowner-friendly transfer process in the industry, and it is a self-serve flow. Go to enlighten.enphaseenergy.com, create a homeowner account with your email, then choose Add System and enter your Envoy serial number. If the system is currently tied to your installer, Enphase will prompt you to upload proof of ownership — a permit, interconnection agreement, or utility bill works.
Approval typically lands in one to three business days. If the self-serve flow stalls, call Enphase homeowner support at 1-877-797-1476 and explain that your installer has closed. They handle that scenario routinely and have a dedicated escalation path.
A common scare: Enlighten shows the system offline, and the homeowner assumes the panels stopped producing. Usually they did not. The Envoy lost its internet connection while the microinverters kept generating kWh. Check the LED on the Envoy — solid green means connected, blinking green means producing but offline, solid red means a hardware problem. A blinking-green Envoy is making power; you just cannot see it remotely yet.
How to claim a SolarEdge monitoring account
The SolarEdge flow is similar. Create a homeowner account at monitoring.solaredge.com, then use Add Site and enter the inverter serial from the label on the wall-mounted unit (not the optimizers). If the site is registered to an installer, click Request Site Ownership Transfer. SolarEdge sends an email to the installer's account, and if no one is left to approve it the request times out after a few days.
When the auto-flow stalls, call SolarEdge support at 1-510-498-3200 or open a ticket through their support portal. Bring your serial number, address, and a single piece of ownership proof. Reference that the installer is closed, and ask for the orphaned-system escalation path. Your full historical production stays in the SolarEdge cloud throughout — nothing is lost in the transfer.
How the SMA, Fronius, Generac, and SolarLog paths work
The remaining platforms follow the same pattern: register a homeowner account, attach your inverter or gateway serial, and call support if an installer account is blocking the transfer. SMA uses ennexos.com (or sunnyportal.com on older systems); their US support line is 1-916-625-0870. Fronius uses solarweb.com with support at 1-877-376-6487. Generac PWRcell systems live on pwrview.generac.com, with Generac Energy support at 1-888-436-3722.
SolarLog is the one outlier worth flagging. It is a physical data logger that sits in your garage or electrical room, often paired with an SMA, Fronius, or ABB string inverter. Because the logger stores data locally, you can sometimes reach a working dashboard by typing its IP address into a browser on your home network, even when the cloud portal is unreachable. Avoid factory-resetting the device without calling SolarLog support first — a reset can wipe your local production history.
What to do if you have lost access completely
If the branded app is gone, your login is rejected, and you never set up a manufacturer account, you can still recover. Start by physically locating your serial numbers. Photograph the label on your inverter or Envoy — the serial is your master key with any manufacturer support team. For Enphase the Envoy gateway serial matters, not the per-microinverter serials. For SolarEdge it is the wall-mounted inverter label, not the optimizers.
Then call the manufacturer directly. Tell them your installer has closed and you need direct homeowner access. Every major brand has handled this routinely since the 2023 to 2026 installer insolvencies, and they have a documented process. Be ready to send one ownership document — your installation contract, building permit, utility interconnection agreement, or a recent utility bill in your name.
Even if the cloud history appears lost, two backup sources usually survive. Your utility bills contain the monthly net kWh imported and exported, which a service contractor can use to reconstruct an approximate production curve. And most inverters keep recent production data in onboard memory that a qualified Solar Partner can read on-site with the manufacturer's service tools.
The most reassuring thing to remember while you sort this out: a dark monitoring app is not a dead system. Walk outside in the middle of a sunny afternoon and look at your utility meter. If the net meter shows credit, or the display is running in reverse, your panels are producing kWh regardless of what any portal is or is not telling you.
