Mia opened it. There, on the cracked screen, was the answer: a two-page spread on fault code E-023. “DC bus over-voltage. Cause: regenerative energy from motor coasting. Solution: extend deceleration time to 5.0 seconds or enable braking resistor circuit.”

: Available in 1AC 220V (0.4kW–2.2kW) and 3AC 380V (0.75kW–11kW). Output Frequency : 0 to 400Hz. Invt CHE100 Inverter User Manualpdf

| Fault Code | Description | Possible Solution | | :--- | :--- | :--- | | | Over-current during acceleration | Check motor wiring; increase acceleration time. | | OV-1 | Over-voltage (DC Bus) | Solar input voltage too high; check PV array configuration. | | LV-1 | Under-voltage | Solar input too low (cloudy/night) or grid voltage too low. | | OH-1 | Inverter Overheat | Clean cooling fan; ensure proper ventilation. | | EF | External Fault | Check water level sensors (Dry run or Tank Full signal triggered). | | OL-1 | Motor Overload | Pump is jammed or head pressure is too high. | Cause: regenerative energy from motor coasting
