Product Description

STACKABLE & HIGH-CAPACITY MODULAR BATTERY

Our residential energy storage system is a flexible and efficient solution designed for managing household renewable energy across varied home types and power requirements. It comes in both high-voltage and low-voltage versions, ensuring compatibility with different solar and grid configurations.

Featuring a modular design, the system allows easy capacity expansion from 5 kWh to over 30 kWh by adding battery units. For homes with limited space, it offers wall-mount installation to maximize floor area. Supporting solar, grid-tie, and backup operation modes, it achieves over 95% round-trip efficiency and uses long-life LFP batteries with 8,000+ cycles.

PV Energy Storage: Seamlessly stores surplus electricity generated by rooftop solar panels.

Peak-Valley Arbitrage: Automatically charges during low-tariff hours and discharges during peak times.

Backup Power: Provides immediate emergency power during grid failures.

Smart Monitoring: Real-time tracking via mobile app.
