Grid Instability Detected
Error 302(00) maps directly to external grid (Enel) dropouts, not internal PV damage.

Root Cause Analysis: Error 302(00)
What is Error 302? The "No AC Connection" error is strictly an AC-side fault. It means the inverter has completely lost its connection to the utility grid (Enel).
COMMON CAUSES (NOT PANEL RELATED)
- Utility grid blackout or severe instability from Enel.
- AC breaker protecting the inverter tripped under surge.
- Physical disruption in the AC cables connecting to the main switchboard.
Critical Note: This is NOT caused by broken diodes, burnt panels, or missing consumption meters. It is a direct cut of AC power to the inverter.

FALHA FÍSICA DETECTADA: PV2 ISOLADO| Métrica | PV1 (Operacional) | PV2 (CRÍTICO) | Diferença / Prejuízo |
|---|---|---|---|
| Voltagem | 380.5V | 46.1V | -334.4V (Falha de Continuidade) |
| Corrente | 8.2A | 0.0A | 100% de Perda |
| Status | MPPT Ativo | STALLED | Abaixo do Startup (100V) |
Workers AI Expert Analysis: A inclinação atual em Niterói para o inverno deve ser de ~37°. Se os seus painéis estão fixos em 22°, você está jogando 15% de energia no lixo agora. A leitura de 46.1V no PV2 não é sombra, é defeito físico (MC4 derretido ou cabo rompido). Ação: Inspeção física imediata da String 2.
