Off Grid Three phase Inverter 20K
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
