Solar Monitoring Not Working — What It Means and What to Do (2026)
If your solar monitoring app is down or showing no production, it could mean a real system problem or just a connectivity glitch. Here's how to diagnose the issue and what to do when your company won't respond.
Quick answer
When solar monitoring stops working, it typically means either the monitoring device has lost its internet or cellular connection (common after router changes or power outages), the monitoring hardware has failed and needs replacement, or the inverter or system itself has stopped producing. A monitoring outage does not always mean your system isn't producing — but it does mean you can't verify whether it is, which can hide production problems for months.
Your solar monitoring app goes offline, shows zero production, or just stops updating. Is your system still working? Is it a network glitch or something serious? And if you report it to your solar company, will they actually fix it? Monitoring failures are one of the most common solar complaints — and one of the most consequential, because they hide real production problems. Here's what you need to know.
What Causes Solar Monitoring to Stop Working
Wi-Fi/network connectivity issues are the most common cause. If you changed your router, changed your Wi-Fi password, or had a modem reset, your monitoring gateway may have lost its connection. The fix is usually reconnecting the gateway to your new network through the monitoring app. This does not mean your system stopped producing — it just means data stopped being sent to the cloud.
Monitoring hardware failure is the next most common cause. The monitoring gateway (a small device that bridges your inverter to the internet) can fail. Enphase Envoy devices, SolarEdge monitoring units, and SunPower monitoring hubs all have hardware lifespans. When they fail, the app shows offline or stale data even if the inverter is still operating. Your installer or manufacturer warranty should cover monitoring hardware replacement.
Inverter failure is the most serious cause. If the inverter has stopped operating, your system isn't producing electricity — and the monitoring showing offline is a symptom of a real production problem. Check whether your electric meter is spinning or recording solar production to distinguish an inverter failure from a monitoring-only issue. See the complete guide on what to do when your solar panels aren't working.
Why Monitoring Outages Are a Hidden Financial Problem
A monitoring outage that lasts weeks or months can mask a real production problem. If your inverter fails in November and your monitoring app just shows "offline," you may not discover the system has been producing nothing until you look at your electricity bills in February. By then, you've paid full utility rates for three months that you expected solar to offset — and the financial damage accumulates before you even know there's a problem.
This is why promptly resolving monitoring issues matters — and why solar companies that are slow to fix monitoring outages are causing tangible financial harm to their customers. If your company failed to address a monitoring outage and your system was producing nothing during that period, document the dates and the production loss carefully. This may support a warranty claim or a misrepresentation claim if the production gap was significant. See more on what to do when your solar company won't respond.
What to Do When Your Monitoring Is Down
Step 1: Check if it's a network issue — reboot your router, check your monitoring gateway's LED status lights, and try reconnecting through the app. Step 2: Check your electric meter. Most smart meters show current solar production. If the meter shows solar production, your system is working but your monitoring has a connectivity issue. Step 3: If the meter shows no solar production, you have an inverter or system issue. Check your inverter's LED status lights — most inverters show a green light when operating normally. Step 4: Contact your solar company in writing (email, not just phone) reporting the monitoring outage and requesting a service visit within 15 business days. Keep that email.
If your solar company doesn't respond, escalate by sending a certified letter to their registered agent. File with the BBB and your state AG if the issue goes unresolved for more than 30 days. For leased systems, the leasing company (Sunrun, Sunnova, etc.) is contractually obligated to maintain the monitoring system — document their failure to do so.
What to Do Next
If your solar company is ignoring your monitoring issue and you have a lease or PPA, get your contract reviewed. A free review at breakyoursolarcontract.com can identify what your contract requires them to do and what remedies you have if they don't do it.

Frequently asked questions
Why is my solar monitoring app showing no production?
Most commonly: a Wi-Fi/network connectivity issue with your monitoring gateway. Less commonly: monitoring hardware failure. Rarely but most seriously: inverter failure. Check your electric meter to determine whether your system is actually producing before assuming the worst.
Does monitoring offline mean my system isn't working?
Not necessarily. Monitoring offline often means the gateway lost its internet connection — your system may still be producing. Check your electric meter or inverter LED status to confirm whether the system is actually operating.
How long should it take to fix solar monitoring?
A simple Wi-Fi reconnection should take minutes to hours. Hardware replacement should take 1-2 weeks for parts and service. If your company hasn't responded in 15-30 business days, escalate in writing and file regulatory complaints.
Who is responsible for fixing monitoring on a leased system?
For leased systems (Sunrun, Sunnova, etc.), the leasing company is contractually obligated to maintain the monitoring system. Document their failure to respond and escalate to state regulatory agencies if needed.
What if my solar company ignores my monitoring complaint?
Send a certified letter demanding repair within 15 days. File with the BBB, your state AG consumer protection division, and the CFPB. For leased systems, the company's monitoring failure may constitute a breach of contract.
Can I sue for lost production from a monitoring outage?
Possibly. If you can demonstrate the system was not producing during the monitoring outage period, and that the company failed to respond to your maintenance requests, you may have a breach of warranty or breach of contract claim for the lost production value.
