6. Complete protection function.

7. 40KG per module, easy and quick inverter system installation.

Modular Design

Hot-plug design, can add and remove inverter module with load, and replace within 10 minutes.

One module shutdown, the others keep on working.

Improve system reliability, reduce loss.

Each module is 40KG, easy and quick inverter system installation, do not need engineering equipments, reduce construction cost and lead time.

Three-Level Topology

Low efficiency loss, maximum efficiency reaches 98.6%.

High power density,50KW inverter module is 440*232*585 mm3.

High switching frequency.

More electricity producing, maximum power gain.

Intelligent Sleeping

Inverter modules automatically turn on/off according to the sunlight. Each inverter module turns on when the prior inverter works over 60% load.

Inverter system automatically and equally assigns inverter’s workload, remains the similar workload/sleeping time of each module, extends the service life of inverters.

Improve system power THDi and PF power quality indicators in weak light condition.

Comparing with traditional central inverter, modular designed inverter needs less energy to start working, reduces power consumption and still keeps working when the sunlight is weak.

Heat Dissipation

Control board, power board and power components are designed to be assembled in separate level.

Independent air flue.

Improve reliability.

MPPT

Software arithmetic invention patent of MPPT, improve MPPT performance on accuracy and rapid response to sunlight and temperature changes.

MPPT efficiency>99.9%

Wide MPP voltage range 470V-850V.

Higher power generation efficiency, maximum power gain.

Comprehensive protection

Over/under voltage, over/under frequency, self-detection of over current, anti-islanding, etc.

Monitoring system

LCD Touch Panel and PC Monitoring Software.

Voltage, current, frequency, power quality information, etc.

Real time and historical power producing information.
