With PQ, VF, VSG, MPPT, DC voltage source, and other operating modes, it can be used as a platform interconnection device to realize low-voltage flexible DC bus interconnection and energy mutual benefit.
PQ (power quality control) grid-connected, voltage grid control, control voltage by controlling current: active power and reactive power are respectively represented by P and Q; PQ mode is the control mode of active power and reactive power; in this mode, active power and reactive power are controllable, simply speaking, constant power; VF (voltage frequency control) Off-grid; virtual synchronous generator (VSG) Virtual synchronous generator MPPT (Maximum Power Point Tracking) in PV mode.
Diesel generators switch to VF mode: voltage/frequency mode, in which the voltage and frequency are controllable and adjustable.
Modular frame design, energy storage battery can run independently, easy maintenance, good scalability.
Can integrate power frequency isolation transformer (optional), strong impact resistance, higher safety, especially suitable for off-grid operation of microgrid system.
Three-level circuit design, high conversion efficiency, improve power utilization (industrial scene)
With a frequency/voltage regulation, VSG, black start function, and off-grid switching function, support multi-machine parallel function.
Charge and discharge conversion time does not exceed 40 ms, and response time is less than 30 ms to meet scheduling requirements or frequency modulation project applications.
With excellent high and low voltage crossing characteristics, SCR=1.05 stable operation ability, and power grid adaptability.

For microgrid scenarios, flexible configuration according to system capacity: energy storage converter module, DC converter module, to achieve integrated optical storage system cabinet.

The system is productized, integrating energy storage batteries, PCS and power distribution, temperature control and fire control, a water sensor, monitoring and communication, and fully controlling the operating status and risks of the system.
Patent outdoor cabinet protection design; optimize heat dissipation duct; protect dust and rain; front and back door maintenance; easy to arrange multiple systems side by side; reduce the floor area.
Door-mounted integrated air conditioning does not occupy the cabinet space, improves the available space of the outdoor cabinet, the top structure integrity is better, and has a good waterproof effect;
Standardized structure design and menu function configuration can be selected for micro-grid and other scenarios, such as photovoltaic charging modules and off-grid switching modules, power frequency transformers and other components, and integrated optical storage integrated system cabinets.
With the patented technology of virtual synchro features, it can realize the function of free parallel and off-grid switching of multiple units without communication lines.
The local control panel can realize the system operation monitoring, energy management strategy formulation, equipment remote upgrade, and other diversified functions.
