Equipped with a built-in 5KVA inverter and 48V energy storage battery, eliminating the hassle of traditional inverter setup, battery wiring, and complex assembly—truly "ready to use out of the box."
Check battery status and power usage remotely via smartphone or computer, keeping you in control no matter where you are.
Features an intelligent BMS that automatically assigns IP addresses and networks connected batteries. If voltage difference exceeds 1.5V, the system isolates charge/discharge circuits to prevent cross-charging and extend battery life.
The BMS communicates with the inverter in real-time, dynamically monitoring charge levels, temperature, and other parameters to intelligently adjust voltage and current—preventing overcharging and overheating risks.
Built-in heating system activates when temperatures drop below 0°C and charging current exceeds 5A, warming the battery to 20°C for stable charging and discharging even in harsh winter conditions.
