Pylontech Error Code 60 – Meaning, Causes & Solution -... | solardiagnostics.org

Technical Background:

Error 60 typically indicates a feedback protection mechanism triggered by the battery management system (BMS). This fault may arise from insulation resistance (RISO) measurements falling below acceptable levels, indicating potential leakage currents. Additionally, the BMS monitors for ground faults, overcurrent, and voltage anomalies, which, if detected, can lead to automatic disconnection to safeguard the battery and the inverter. The logic behind this protection is to prevent damage that could arise from conditions such as thermal runaway or short circuits.

Symptoms:

Users may observe the LED indicator flashing a specific pattern associated with Error 60, often accompanied by alerts on the monitoring app indicating a fault condition. The system may also exhibit a drop in production, with the inverter ceasing to deliver power to the load or grid.

Possible Causes:

Insulation resistance failure due to moisture ingress or degradation of insulation materials.
Overvoltage conditions detected by the battery management system (BMS) due to improper charging or environmental factors.
Internal battery cell imbalances leading to excessive current draw or thermal runaway.
Faulty connections or corroded terminals within the battery or junction box impacting overall system integrity.
Inadequate grounding or ground faults detected, triggering protective measures in the BMS.
Temperature extremes causing the BMS to activate safety protocols to prevent damage.

Solution:

1

Use a multimeter to measure insulation resistance between the battery terminals and the ground. Ensure readings are above 1 MΩ.
2

Inspect all connections and terminals for corrosion or looseness. Clean and tighten as necessary.
3

Check the system voltage and compare it to the manufacturer's specifications to identify any overvoltage conditions.
4

Verify that the temperature of the battery is within operational limits; if not, assess the system environment.
5

Use a thermal camera to inspect for hot spots in the battery or connections, indicating potential internal issues.
6

If necessary, disconnect the battery from the inverter using an MC4 disconnect tool before performing further diagnostics.
7

Reset the system by following the manufacturer's instructions for clearing fault codes once issues are resolved.

Safety Warning:

Always consult a licensed electrician or certified solar installer when performing diagnostic procedures or repairs on solar battery systems.

Prevention:

To avoid encountering Error 60 in the future, ensure regular maintenance is performed, including inspections of insulation integrity, terminal connections, and environmental conditions. Implement proper grounding techniques, and monitor system performance through the app regularly to catch issues early.
