EESNB 200KW Off-Grid Power Frequency Inverter Three phase


Off-grid Connection


Features

◆  Complete isolation-type inverter technology, noiseless output.

◆  Adoption of advanced SPWM technology, pure sine wave output.

◆  Dynamic current loop control technology to ensure inverter reliable operation.

◆  Wide DC input voltage range.

◆  Excellent EMC design.

◆  Low output harmonic distortion (THD≤3%).

◆  LED indicators for input voltage range, load power range, normal output & failure state.

◆  Optional energy saving mode.

◆  Extensive protections: reverse polarity, short-circuit, overload, under/over input voltage over-temperature, and inverter’s inner fault identification protections.

◆  Wide working temperature range (industrial level).

◆  Continuous operation at full power.


Application:

◆  For desolate area like mountain, island, pasturing area, etc.

◆  For transportation system like beacon light, traffic light, street light, etc.

◆  For communication system: unattached operation microwave middle station, optical cable maintenance station, etc.
