Overload Fault
Over Load in EPS Mode.
• Turn off high power device , press “ESC” to restart the
inverter.
• Or seek help from us, if cannot go back to normal state.
EPS OCP Fault
Over Current in EPS Mode.
• Make sure the load power is within the EPS power range.
• Check if any nonlinear load is connect on the EPS. Remove
this load
to check if can recover.
• Or seek help from us, if cannot go back to normal state.
DCI Device Fault
DCI Device Fault
• Disconnect solar power PV+ , PV- and battery, reconnect
them.
• Or seek help from us, if cannot go back to normal state.
AC HCT Fault
AC Current Sensor Fault
• Disconnect solar power PV+ , PV- and battery, reconnect
them.
• Or seek help from us, if cannot go back to normal state.
EPS Relay Fault
EPS Relay Fault
• Disconnect solar power PV+ , PV- , grid and battery,
reconnect them.
• Or seek help from us, if cannot go back to normal state.
TZ Protect Fault
Over current Fault.
• Wait for a while to check if go back to normal status.
• Disconnect solar power PV+ , PV- and battery, reconnect
them.
