Three-phase Energy Storage Converter (Isolated Type)
Power grid adaptability
• Meeting the smart grid design specification and allowing power grid dispatching
• Advanced islanding detection technology
• Reactive power compensation and other functions
• Off-Grid independent operation

System characteristics
• Completely isolation of batteries from the power grid
• Charging and discharging time setting for 12 segments, better for customer's on-site applications
• On/off grid switching time: general conditions
<200ms; zero transition can be achieved under specific conditions (external connection of SCR)
• Four periods of time (peak, flat, valley and sharp) price setting, flexible calculation of user profitability
