Solar Not Producing After a Power Outage: What to Check

It is common for solar systems to look "down" after a power outage, a utility event, or a meter swap. Sometimes the system is actually producing and only the monitoring is delayed. Other times the inverter is waiting for stable grid conditions before it turns back on. This guide helps you verify what is happening without tools and without opening any equipment.

Start Here: Is the Grid Fully Back?

Solar inverters must see a stable utility grid to operate. If the grid is unstable, the inverter will stay off for safety. Before assuming solar failed, confirm:

• Your home power is fully restored (not partial power to only some circuits)
• Your neighborhood is not having repeated brief outages or flickering power
• If you have a battery, note whether the home is currently running on backup mode
• Your utility did not leave a shutoff notice or "work completed" door tag (if they worked on your service)

Check Monitoring the Right Way (Avoid False Alarms)

After an outage, monitoring may lag, lose communication, or show "zero" even if production is returning. Do these quick checks:

• Look for a "last updated" timestamp in your app (note the date/time)
• Switch to "Week" or "Month" view to see whether production truly dropped to zero after a specific day
• If the app shows "No communication" or "Gateway offline," the issue may be reporting only
• If you have a battery app, check whether the battery is charging during daylight hours

Use Your Utility Info to Confirm (Even If the App Is Wrong)

Your utility data can help confirm whether solar is exporting energy. Depending on your utility, you may see this in a daily usage view or billing portal. Look for:

• Export / "delivered to grid" line items (or negative net usage during sunny hours)
• A noticeable reduction in net usage compared to similar weather days
• A change that starts exactly on the outage date (helpful for timeline matching)

What "Normal" Can Look Like After an Outage

Many inverters wait before reconnecting to the grid. These "normal" behaviors can happen:

• Production stays at zero for a period, then returns later (especially if the grid was unstable)
• Monitoring shows stale data for hours or a day, then "catches up"
• Gateway/monitoring goes offline because the router restarted or Wi-Fi changed
• If you have batteries, the system behaves differently while it re-establishes grid mode

Signs It Might Be a Real Production Issue

Monitoring problems are common. These signs point more toward an actual production issue:

• Your app shows zero production and your utility data shows no export for the same period
• Your inverter display shows "Fault," "Shutdown," or a repeated error message (photo helps)
• Production never returns after the outage date (more than a day of sunny hours with no export)
• Your electric bill spikes and the timing matches the outage and "last updated" timestamp

What Not to Do

• Do not open the inverter, disconnects, main panel, or any wiring enclosure
• Do not remove solar panels or attempt rooftop troubleshooting
• Do not repeatedly flip breakers or switches if you are unsure what they control
• Do not ignore safety-related alerts like ground fault / isolation warnings

Next Steps

If production is not returning and you want help confirming whether this is monitoring-only or a real issue, contact us and we will review your situation and outline the best path forward.

What to Send Us for a Fast Answer

To quickly determine whether this is a monitoring problem or a real production issue, send:

• A screenshot of your monitoring "Month" view
• A screenshot showing the "last updated" date/time (or "No communication" message)
• Any error message screens (if shown)
• A photo of the inverter display (if visible without opening anything)
• A screenshot of the utility page that shows usage and export (if available)
