Features

Plug-and-Play Integrated Design

Integrated with 48V battery and 5KVA inverter. No complicated wiring required, ready for grid connection right out of the box.

Smart Parallel Connection with Old & New Battery Compatibility

Auto IP assignment for network grouping. Automatically isolates circuits when voltage difference exceeds 1.5V to avoid mutual charging damage.

Dynamic Proactive Charge Control

Real-time communication between BMS and inverter realizes dynamic voltage and current adjustment, eliminating overcharge and overheating risks.

Dual Remote Monitoring via Phone & PC

Supports remote battery status and power consumption checking via mobile phones and computers for convenient household energy management.

Flexible Capacity Expansion

Supports parallel connection of multiple batteries for flexible capacity expansion to match different household electricity demands.

-30℃ Extreme Low Temperature Adaptation

Built-in heater activates automatically below 0℃ (charging current ≥5A), maintaining constant 20℃ working temperature for stable operation in severe winter.
