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.
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.
High Solar Input Voltage Overload
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.
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.
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.
