Gateway Systems¶

Every microinverter platform requires a local gateway device to aggregate production data and forward it to cloud monitoring.

Gateway Comparison¶

Gateway — Field Checklist¶

When visiting a microinverter site:

• [ ] Gateway located and powered on
• [ ] Gateway indicator lights in expected state
• [ ] Gateway connected to network (Ethernet or Wi-Fi)
• [ ] Gateway shows in monitoring portal as online
• [ ] Last communication timestamp recent

Gateway Troubleshooting¶

No Internet Connectivity¶

1. Check physical Ethernet cable (if wired)
2. If Wi-Fi: has network SSID or password changed?
3. Check router — is DHCP working?
4. Restart gateway (power cycle)

Gateway Online but Missing Units¶

• Check if units are producing (measure AC at branch circuit)
• Enphase: PLC communication issue — check AC wiring continuity
• APsystems: ZigBee range — move ECU closer to array

Gateway Offline Entirely¶

• Check power at gateway location
• Check circuit breaker for gateway outlet
• If gateway is physically damaged: replacement required
