Value Assessment: At $2799, this unit costs approximately $0.68 per watt-hour of capacity, comparable to premium competitors. When factoring in expandability, LFP longevity, and warranty coverage, the cost per usable year of service becomes competitive. The ability to scale from 4kWh to 48kWh without replacing the base unit provides long-term value justification.
