CODE E011 AC240 High

PV Input Overvoltage Shutdown

The Bluetti AC240 hardware protection triggered Error E011 due to open-circuit voltage (Voc) at the DC/PV input exceeding the maximum rated threshold of 60V DC. The internal MPPT step-down controller has isolated the PV input bus via protective MOSFET switching to prevent gate breakdown and capacitor failure.

CODE E088 AC200L Portable Power Station High

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 E088 AC200L High

MPPT Over-Voltage Lockout Fix

Error code E088 indicates that the DC input voltage to the internal MPPT controller has exceeded the maximum rated safe threshold (145VDC), triggering a hardware-level safety shutdown to prevent buck converter MOSFET breakdown.

CODE E049 AC200L High

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 E041 AC200L Critical

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.

CODE E034 AC200L High

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.
