When making a purchase, consider these key specifications:
Cycle Life: High-quality lithium batteries can achieve 6,000 cycles.
Conversion Efficiency: The overall AC-AC efficiency should ideally be ≥90%.
Safety Protections: Must include safeguards against overcharging, over-discharging, and temperature-related issues.
Expandability: Check whether the system supports the addition of extra battery modules later on.
Smart Features: Ideally, the system should support learning your energy usage patterns and offer remote control capabilities.
