4 Codes
CODE E088 Severity: High Difficulty: Easy

High PV Input Voltage Lockout

Error code E088 triggers when the open-circuit voltage (Voc) applied to the DC/PV input exceeds the hardware protection threshold of the internal MPPT controller (rated maximum 145V DC). The firmware initiates an immediate charge lockout to prevent catastrophic MOSFET breakdown.

CODE E049 Severity: High Difficulty: Intermediate

MPPT Solar Over-Voltage Protection Trip

The internal MPPT charge controller detected open-circuit voltage (Voc) exceeding the maximum hardware safety threshold of 145V DC on the DC/PV input port, triggering hardware protection to prevent catastrophic damage to the buck-boost conversion circuitry.

CODE E034 Severity: High Difficulty: Intermediate

Solar MPPT Input Overvoltage

Error E034 indicates the internal MPPT charge controller detected incoming DC voltage from the solar/PV array exceeding the maximum hardware safety threshold of 145V DC, triggering automatic hardware shutdown to protect the front-end MOSFETs.

CODE E041 Severity: Critical Difficulty: Intermediate

PV Input Overvoltage Trip

Error E041 indicates that the DC/PV input voltage exceeded the maximum open-circuit limit of 145VDC, triggering the internal MPPT hardware overvoltage protection and latching the input relay to protect the DC-DC buck stage.
