Frequently Asked Questions
•What is the typical lifespan of an Enphase IQ Battery 10T before significant SOC drift occurs?
The Enphase IQ Battery 10T is designed for a lifespan of approximately 10 years or 3650 cycles to 70% of original capacity. However, noticeable SOC drift can occur earlier, especially after 1000 cycles, depending on usage patterns and environmental conditions.
•How can I verify if the temperature sensors in my IQ Battery 10T are accurately reporting temperature?
Compare the temperature readings from the Enphase monitoring app with an external calibrated thermometer placed near the battery. Significant discrepancies (more than 5°C) may indicate a faulty sensor. Use the Enphase Installer Toolkit for advanced diagnostics.
•Does Enphase offer any extended warranties or service programs to address SOC drift issues in older IQ Battery 10T models?
Contact Enphase customer support or your installer to inquire about extended warranty options or service programs specifically designed to address SOC drift or battery degradation in older IQ Battery 10T systems. Review your original warranty documentation for coverage details.
