Isolated type low pressure energy storage converter

Low-voltage energy storage converter is suitable for the construction of smart power grid, which has the advantages of ensuring the safety of power grid and regulating electricity consumption.

• Synergistic function of landscape firewood storage
• Rapid island detection technology
• The system is completely isolated from the grid
• Reactive power compensation and harmonic compensation functions
• Constant power, constant current charging and discharging function
• Zero switching can be achieved off the grid (SCR is required)
• Time-divided charging and discharging function, can be configured according to field needs
• Electricity price setting for four periods (peak, flat, valley and peak), flexible calculation of user profit

Generation-side energy storage: load regulation, smoothing intermittent energy, increasing consumption of new energy, increasing reserve capacity of power grid, participating in peak regulation and frequency modulation.

Transmission and distribution energy storage: improve power quality, reduce line loss, improve the reserve capacity of the grid, improve the utilization efficiency of transmission and distribution equipment, and delay the demand for capacity increase.

User-side energy storage: smooth load curve, load transfer, peak clipping and valley filling.

Emergency power supply system: it is in standby state when the power grid is normal, and it can be started when the power grid is faulty to guarantee the continuous power supply of the load.

Fire power supply, emergency lighting, energy feedback, etc.
