The service life of home energy storage batteries is closely related to seasonal maintenance and long-term usage habits. In high-temperature summer, strengthen ventilation and heat dissipation, and avoid long-term high-load discharge to prevent battery overheating and attenuation. In low-temperature winter, battery activity and capacity will decrease temporarily; avoid frequent high-power discharge and use the device at room temperature to prevent cell damage. Clean solar panels regularly to ensure charging efficiency for PV energy storage systems. Conduct a full annual inspection to eliminate hidden dangers of circuits, cells and BMS, which greatly improves the stability and service life of energy storage equipment.
