Error E06 triggers when the DC input voltage to the MPPT charge controller exceeds the maximum absolute rating (60V DC on the low-voltage XT60 port or 140V DC on the high-voltage XT-60 port), causing the internal hardware over-voltage protection (OVP) circuit to trip and isolate solar charging to prevent MOSFET breakdown.

CODE E04 SOLIX F3800 High

Inverter DC Bus Overvoltage Trip

Error E04 triggers when the bi-directional inverter internal DC bus voltage exceeds safe hardware thresholds (typically >420V-450V DC). This occurs primarily during aggressive regenerative backfeed from inductive loads, solar PV open-circuit spikes, or rapid grid voltage fluctuations during AC pass-through.

CODE E03 SOLIX F3800 High

Inverter DC Bus Overvoltage

Error E03 triggers when the internal bidirectional inverter's high-voltage DC intermediate bus exceeds its safe operational voltage threshold (typically over 420V-450V DC). The Power Management System (PMS) locks out AC output and charging circuitry to prevent catastrophic failure of the primary IGBTs and bus capacitors.

CODE E06 SOLIX F3800 High

AC Inverter Overload Short Circuit

Error E06 indicates that the high-voltage AC pure sine wave inverter hardware protection circuit detected an instantaneous overcurrent, short circuit, or continuous load exceeding the 6,000W split-phase threshold, prompting a safety gate shutdown.

CODE E32 SOLIX F3800 High

AC Inverter Overload Cutoff

Error code E32 indicates the bidirectional AC inverter sustained an instantaneous current or sustained wattage draw exceeding safety thresholds (typically >6000W surge or sustained >3840W continuous output), triggering software hardware protection to isolate the H-bridge MOSFETs.

CODE E041 SOLIX F3800 Critical

AC Output Short Circuit Overload

Error E041 indicates that the inverter microprocessor detected an immediate AC output short-circuit condition, an instantaneous peak current overload exceeding hardware thresholds (such as 6000W surge limit), or backfed AC voltage on the NEMA 14-50 or L14-30 output ports.

CODE E01 SOLIX F3800 Plus High

AC Inverter Overload Lockout

Error E01 triggers when the bidirectional inverter detects an AC output current or wattage spike exceeding continuous (6,000W) or peak surge (9,000W) thresholds, an active downstream dead short, or a neutral-ground bonding phase conflict via an external transfer switch.

CODE E04 SOLIX F3800 Plus High

AC Output Overload Trip

Error Code E04 indicates that the internal digital signal processor (DSP) detected an AC output overcurrent or excessive surge demand exceeding continuous (6,000W) or peak (9,000W for >200ms) inverter thresholds, or encountered a severe phase imbalance across the split-phase L1/L2 120V/240V legs.
