Inverter is stuck in EPS mode

FAQ\Hybrid INV

Issue introduction

The INV is stuck in EPS mode, even if the grid side wiring is normal and has been restored, it cannot be converted to Normal state.

Make sure that the wiring on the AC side of the INV is good, including the terminals are not loose and the wire sequence corresponds correctly.

Guidance for installer

Step1: Use a multimeter to measure the voltage at the inverter's AC port. In a three-phase system, measure the line voltage.


Phase voltage on the grid side	grid line voltage(line voltage＝√3×Phase voltage)

Step2: Check the system status sampling information, which inverter displays on the screen. Ensure the detection of grid voltage in the inverter is normal.

Settings path: About → System status → On-grid

Information check list

If you have completed the above <Guidance for installer>, and the problem is still not solved, please collect the following troubleshooting information and send them to the Solax technical support team.
