Solar Inverter 30kW
Technical Characters
Low Loss Siemens Devices and IGBT
MPPT self-optimizing technology maximizes the system power generating capacity, MPPT efficiency >99.9%
System efficiency up to 97%
Lower current harmonic distortion rate, THD<3%
Double DSP control, powerful functions, super performance, high precision output, and high precision output power calculation
Man-machine interface LCD displaying
Excellent Electromagnetic compatibility; Inverter current double closed-loop control, the current harmonic low,non-polluting, non-impact to grid
Multi-module redundancy design, allowing the module automatically takes off from the bus in case of fault conditions, the rest of the module of continuous operation without interruption. Greatly facilitate for the installation, commissioning and maintenance;
RS485/232 or Ethernet communication interface;Remote monitoring and control functions
Safe and effective, professional protection
Overvoltage protection, shortage protection, island protection, over heat protection, overload and DC grounding protections;
