3 Codes

CODE 08 Severity: Critical Difficulty: Advanced

Bus Voltage Too High

Error Code 08 represents an internal DC bus over-voltage condition (exceeding 500VDC internally). This is a critical protective shutdown to protect the main capacitor bank and IGBT bridge from catastrophic rupture.

CODE 02 Severity: Medium Difficulty: Easy

Heatsink Over Temperature

Error Code 02 triggers when internal thermal sensors register temperatures exceeding 90°C (194°F) on the main power MOSFET heatsink or transformer core.

CODE 04 Severity: High Difficulty: Intermediate

Low Battery Voltage

Error Code 04 indicates that the battery bank voltage has plummeted below the low-voltage cutoff threshold configured in the inverter settings, prompting an emergency shutdown to prevent irreversible battery cell degradation.
