How to Monitor Solar Battery Health Monitoring your solar battery is essential for extending its lifespan, ensuring efficiency, and avoiding costly repairs. Here's a quick rundown of what you need to know: - Why Monitor? Without monitoring, your battery risks overcharging, undercharging, or temperature damage, which shortens its lifespan. Proper care can extend lithium-ion battery life to 15–20 years and up to 10,000 cycles. - What to Track: - State of Charge (SOC): Keep it between 20–80% to prevent damage. - Voltage & Current: Ensure proper charging/discharging to avoid stress and heat buildup. - Cycle Count: Know the remaining lifespan based on usage cycles. - Temperature: Maintain an ideal range (68°F–77°F) to avoid degradation. - Internal Resistance: Monitor for increased resistance, which signals aging. - Tools to Use: - Multimeters: For manual voltage and current checks. - Shunt Monitors: Offer real-time, detailed data. - Inverter Systems: Provide basic battery metrics and solar ...
