Symptoms:
A single Maximizer is not communicating.
Troubleshooting Steps:
If mesh node count (found in the Hub section of Grafana) exceeds the number of communicating Maximizers, ensure the entire system is on 25.24.04 or later Firmware to attempt recovery.
Check Maximizer Inputs (requires roof access).
Power cycle the maximizer if roof access is available (see article 99.5 Power Cycle Lunar Maximizer). If roof access is not available, skip to step 4 — proceed with a Gridshare remote reset and plan to bring a spare Maximizer to the next visit.
Reset nearby Maximizers in Gridshare (see article 4.7 Reset Maximizer in Gridshare).
Note: Power cycling is the last step before RMA. If the Maximizer does not recover after a Gridshare remote reset and power cycle, the unit likely needs to be replaced. Bring a spare Maximizer to the next site visit — attempting power cycling without roof access is not possible and should not delay the escalation path.
