Off-grid Inverter

Off-grid inverter converts the DC to AC for the loading. We can according to user requirements, increase the utility charge, mains bypass, and other functions.

Deming off-grid inverters include two types: high frequency off grid inverters and industry frequency off grid inverters (with isolated transformer), applied to different territories. Industry inverters (with isolated transformer) includes single phase off grid inverter and three phase off grid inverter.


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.

? For photovoltaic power station, wind-solar (diesel) power station, park charging station, family power house, factory power station, etc.

? For solar building: has good business future.

? For the new technology application project


Power Frequency Pure Sine Wave Inverter 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 (THDw3%).

?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 inverter1 s inner fault identification protections.

?Wide working temperature range (industrial level).

?Continuous operation at full power.
