All your solar panels stopped at once? It's usually a tripped breaker. Here's a 5-minute checklist from Rivertown Solar
If your solar app suddenly shows every panel at zero, don't panic. The most common cause we see is a tripped or switched-off breaker, and you can often check it yourself in about five minutes.
At Rivertown Solar, many of the "my system is down" calls we get from Westchester homeowners end the same way: a breaker in one of the boxes outside the house is off. Here's how to tell whether that's your problem, which boxes to check, and when to stop and call us.
Panels almost never fail together. Most systems we install use microinverters, one small inverter under each panel. Each one runs and reports on its own, so a hardware problem usually takes out one or two panels, not the whole roof.
That's why it matters when your app shows every microinverter stopping at the same minute. The panels are probably fine. What stopped is the AC power they need to connect to your home, and a breaker or disconnect switch sits on that path.
When this happens, our support team checks your site remotely first. If the gateway is online but all the microinverters stopped together, we tell customers the same thing every time: "This typically indicates that an AC breaker may have been tripped."
One quick check before you go outside: if the app says the gateway is offline too, you may just have a WiFi problem. That's covered in the last section.
Only flip switches and handles you can reach without tools. Never take off a panel cover, open the panels on your roof, or touch wiring.
Go through the boxes in the order the power flows: from your roof, to the outside of the house, to your main electrical panel. Take a photo of each box before and after. Those photos let us diagnose most problems without a site visit.
Did you have electrical work done recently? New batteries, generators, EV chargers, panel upgrades and inspection fixes can all leave a solar breaker switched off. If your system went quiet right after someone worked on your electrical, check the breakers first.
These are real 2025–2026 support cases from our customers.
| What the homeowner saw | What it turned out to be | How it got fixed |
|---|---|---|
| Alert: "microinverters not reporting." The gateway was online, and every microinverter had stopped at the same moment. | Both 20A breakers inside the Enphase combiner box were off. There was also water inside the box. | The homeowner switched the breakers on and sent photos. Two microinverters still weren't reporting afterward, so we opened a case with Enphase and got warranty replacements. The system was back to 100% in about a month. |
| "7 panels in the front are not working again." | A tripped breaker on one branch circuit. | The homeowner reset it the same day. Because it was a repeat, we checked whether a fault or the grid was causing it. |
| "Half my panels have stopped working." | We suspected a breaker, but the photos showed every breaker was on. The real cause was failed microinverters or loose wiring on the roof. | A manufacturer warranty replacement, which typically takes 10 to 20 business days. |
| "Microinverters not reporting" for about a week. | No breaker had been touched. It was a communication gap, and the system had kept producing power the whole time. | It came back on its own. The homeowner added a signal-boosting router so it wouldn't happen again. |
The lesson: if all your panels stop at once, check the breakers first. If the breakers are fine, your photos still save a truck roll, because they help us tell a breaker problem from an equipment failure or a WiFi problem.

Every day your system is down costs you net-metering credits on your Con Ed bill, so don't wait for the monthly statement to find out. Turn on production alerts in your Enphase app, and check the app once a week.
