Solar monitoring offline (system still running)

Use only checks that match the exact appliance or system and its official guide.

1. Check 1

   During daylight and without opening or touching the inverter, read the installed system's normal display, status lights, or manufacturer-authorized local app view using the exact model instructions.

   Expected result: Record whether the local status explicitly reports production or output, reports communication only, shows an error or shutdown state, or is blank and cannot be interpreted from the manual.

   Next step: Photograph the display or lights and record the exact time, sunlight conditions, and model before checking the gateway or router; contact the installer if local production is absent, an error is present, or the status cannot be interpreted safely.

   Stop if: Do not remove covers, touch DC connectors, operate unfamiliar disconnects, reset a fault repeatedly, or take measurements on exposed electrical equipment.

   Why this matters

   Why: A valid local production indication while the portal is offline supports a telemetry or network problem rather than an immediate generation failure. A no-production or error indication means the offline alert may be accompanying a real inverter, grid, array, or control issue; a blank or unfamiliar indication is inconclusive.

2. Check 2

   Compare the local production indication with any user-accessible production meter, utility interval data, or the home's normal daytime import/export indication, without opening the meter enclosure or relying on a stale app graph.

   Expected result: Classify the result as local production and independent meter evidence both present, local production present but meter data stale, no local production and no independent evidence, or readings that cannot be compared because the system has storage, net metering, or a different measurement point.

   Next step: Save the comparison and the time window for the installer; do not change export settings, battery controls, meter wiring, or utility equipment to force the readings to match.

   Stop if: Stop for an abnormal meter message, exposed conductors, arcing, heat, burning odor, water intrusion, or any request to open utility or inverter equipment.

   Why this matters

   Why: Agreement between a current local status and independent meter evidence makes a reporting outage more likely. A stale or missing meter can be a separate meter, CT, gateway, or data-path issue. No production evidence raises the priority of an installer diagnosis, while battery or net-metering behavior can make a simple utility-meter glance misleading.

3. Check 3

   From ordinary user access, check whether the monitoring gateway or communications device has normal power and whether the home router or internet connection changed, rebooted, lost service, changed Wi-Fi credentials, or moved ports recently.

   Expected result: Record gateway power or network indicators, router/internet status, recent password or firewall changes, and whether other household devices are online; do not open the gateway or inverter to reseat internal cables.

   Next step: Follow only the installed manufacturer's documented user-level network recovery, such as restoring the known router connection or checking an accessible plug, and record the result; ask the installer or monitoring provider to reconfigure the gateway when credentials, firmware, cellular service, or internal wiring is involved.

   Stop if: Do not factory-reset the gateway, change inverter communication settings, update firmware from an unverified file, or cycle AC/DC equipment as a network fix.

   Why this matters

   Why: If the gateway is unpowered or the household network changed while local inverter production remains normal, the offline state is more likely in the gateway-to-router or router-to-cloud path. If the router is normal but the gateway is unresponsive, the gateway or its power supply needs model-specific support. Network recovery does not prove generation is healthy.

4. Check 4

   Check the portal's alert scope and last-seen timestamp, looking for whether the outage covers the whole site, only the inverter, only module-level devices, only a production or consumption meter, or only one monitoring account.

   Expected result: Record the last successful report, device or meter named in the alert, whether the local inverter is still producing, and whether other devices or sites under the same account remain visible.

   Next step: Send the alert text, timestamp, affected device count, local status, and network observations to the installer or monitoring provider; do not infer a failed panel from an isolated telemetry alert.

   Stop if: Do not enter the inverter communication compartment, disconnect RS485 or Ethernet wiring, alter CT orientation, or change site/account settings without qualified instructions.

   Why this matters

   Why: A single-device or meter-only alert points toward a device link, CT/meter, RS485 or local communications path, while a whole-site outage points toward gateway, internet, account, cloud, or site power. A long stale timestamp increases the chance that production loss has gone unobserved and should be escalated even if the inverter looks normal.

5. Check 5

   Contact the original installer, a qualified solar service provider, or the monitoring provider with the model, local status, meter comparison, alert scope, network changes, and photos; request separate checks for production and telemetry.

   Expected result: Ask the provider to state whether the site is generating, whether data is being buffered locally or lost, which link failed, whether a meter or communications module is involved, and whether any electrical or firmware work is required.

   Next step: Follow the provider's model-specific recovery plan and verify that a new current production report appears after repair; retain the outage interval because portal backfill and utility billing may not use the same data source.

   Stop if: Do not open, repair, or bypass the inverter, optimizer, microinverter, battery, meter, or DC/AC disconnects yourself; stop for smoke, arcing, heat, water, exposed wiring, or a burning smell and seek urgent qualified help.

   Why this matters

   Why: A confirmed communication-only outage can be repaired in the network, gateway, or monitoring account while the array remains in service. A production fault, inverter fault, grid event, or meter failure needs electrical diagnosis and may require the system to remain out of service until safe.
