Learn about Samil Power SolarRock Error Code 2, its causes, and how to fix it effectively.
Error Code 2 typically indicates an isolation fault within the inverter system. This can affect the overall performance and safety of the solar installation.
To troubleshoot Error Code 2, check the wiring and connections for any signs of damage or disconnection. Ensure that the inverter is properly grounded and that all components are functioning correctly.
Error 2 indicates an isolation fault, which occurs when the inverter detects a failure in insulation resistance. This is critical for ensuring safety and preventing ground faults that could lead to electric shock or fire hazards. The inverter continuously monitors the insulation resistance (RISO) of the string and its internal components. If the resistance falls below a predefined threshold, the inverter triggers this fault to protect itself and the connected array from potential damage.
Homeowners may notice the inverter displaying Error 2 on the LED indicator or monitoring app. This often correlates with a significant drop in power production, leading to lower energy yield. In some cases, the inverter may enter a shutdown mode, preventing any energy conversion from the solar array.
Always ensure that a licensed electrician or certified solar installer performs troubleshooting and repairs to avoid electrical hazards.
Regular maintenance, including visual inspections of wiring integrity, connections, and grounding, can prevent future insulation faults. Additionally, ensure that the system site is free from debris and that the array is clean to minimize environmental impacts.
