Learn about Solis G-IMP error, its causes, and how to fix it effectively.
The G-IMP error typically indicates an issue with the inverter's AC cable resistance. This can affect the inverter's performance and efficiency.
To check AC cable resistance, use a multimeter to measure the resistance across the cable. Ensure the system is powered off before performing this test.
The G-IMP fault code typically indicates an issue related to the inverter's AC output. This error can arise from a variety of electrical faults, including excessive resistance in the AC cable, which may trigger the inverter's internal safety mechanisms. The inverter continuously monitors for ground faults and voltage anomalies, and if it detects conditions outside of its operational parameters, it will halt production to prevent damage. Ground fault detection relies on insulation resistance measurements, and if these readings fall below acceptable thresholds, the inverter will trigger the G-IMP fault code.
Homeowners may observe the inverter displaying the G-IMP fault code on the monitoring app or directly on the inverter interface. LED indicators may blink or remain lit in a specific pattern, signaling an operational issue. Additionally, there may be a noticeable drop in energy production, with the system failing to meet expected output levels.
Always consult a licensed electrician or certified solar installer when troubleshooting or repairing solar equipment. Working with electrical systems can be hazardous, and proper safety protocols must be followed.
To prevent the G-IMP error in the future, ensure regular maintenance of the solar array and inverter, including periodic inspections of wiring and connections. Implement a routine insulation resistance test to catch potential ground faults early. Additionally, ensure that the system complies with NEC regulations regarding grounding and wire sizing to mitigate risks of electrical faults.
