Features
Integrated BMS monitoring
The built-in Battery Management System continuously monitors individual cell voltage (2.5–3.65 V), total pack voltage (48–51.2 V), current (0–100 A), and temperature (−20 °C to 60 °C). It provides over-charge, over-discharge, short-circuit, and temperature protections, and balances cells to extend service life and maintain consistent performance.
Modular scalability
Supports flexible configurations from ~4 kWh single-home setups to >15 kWh larger installations. Packs can be connected in series or parallel, maintaining voltage stability and safe operation while scaling capacity according to household energy demands.
Strong power delivery
Continuous discharge currents range from 50–100 A, with short-term peaks up to 150 A. This enables support for multiple high-demand appliances simultaneously and accommodates surge loads such as HVAC systems or electric water heaters.
Long service life
Rated for over 6,000 full charge/discharge cycles at 80% depth of discharge, with capacity retention above 80% after 10 years under standard residential usage conditions, ensuring reliable, long-term energy storage.
Applications
Ideal for residential solar-plus-storage systems, home backup power, and smart energy management solutions. The battery integrates seamlessly with common inverters and can be configured in series or parallel to meet varying capacity and load requirements.
