1. Inverter fault screen display
Single-phase inverter
Three-phase inverter
2. Solution
1: Use a multimeter to check whether there is voltage between the neutral wire and the ground wire. Under normal circumstances, the voltage between the neutral wire and the ground wire is less than 10V; if it exceeds the normal range, start from the inverter end, measure the neutral wire and the transformer end to find out the problem.
2: Rewire the AC side. If the wiring is unreliable, the machine will also report an error.
3: If the problem has not been solved, please contact the after-sales service hotline.
