Working Diagram

Inverter is a necessary unit for the off-grid power system or backup power system.


In an off-grid power system, the inverter plays a crucial role in converting the DC (Direct Current) power stored in batteries or generated by renewable energy sources into usable AC (Alternating Current) power for running electrical devices and appliances. 


In a backup power system, the inverter serves a critical role in providing electricity during power outages or when the main grid supply is unavailable. When main grid power is available, the inverter charges the battery.

Application for off-grid three-phase inverters

Off-grid three-phase inverters have a wide range of applications across various sectors where reliable and independent power supply is crucial.


Here are some common applications of off-grid three-phase inverters:


Industrial and Commercial Facilities: Off-grid three-phase inverters are commonly used in industrial and commercial settings, including manufacturing plants, warehouses, office buildings, and data centers. These facilities often have high power demands and require a stable three-phase power supply for machinery, equipment, HVAC systems, and lighting.


Agriculture and Farming: Off-grid three-phase inverters are essential in agricultural applications, such as farms and ranches. They power irrigation systems, water pumps, grain drying systems, livestock equipment, and other agricultural machinery that operate on three-phase power.


Remote and Rural Areas: Off-grid three-phase inverters are ideal for providing electricity in remote or rural areas where grid access is limited or nonexistent. They enable the establishment of independent power systems, including microgrids, to meet the energy needs of communities, schools, healthcare facilities, and businesses.


Telecom Towers and Base Stations: Off-grid three-phase inverters play a critical role in powering telecom towers and base stations located in remote or off-grid locations. They provide a reliable three-phase power supply for uninterrupted communication services, ensuring connectivity and network reliability.


Mining and Oil & Gas Operations: Off-grid three-phase inverters are widely used in mining and oil & gas operations, especially in remote and off-grid sites. They power heavy machinery, drilling equipment, pumps, compressors, and other critical systems that require a stable and continuous three-phase power supply.


Construction Sites: Off-grid three-phase inverters are employed in temporary or remote construction sites where grid power is not readily available. They provide reliable power for construction equipment, tools, lighting, and temporary facilities.


Event and Entertainment Industry: Off-grid three-phase inverters are used in the event and entertainment industry to power large-scale sound systems, lighting rigs, stages, and other equipment that require three-phase power. They ensure seamless operations and uninterrupted performances in outdoor or off-grid event venues.


Remote Monitoring and Surveillance Systems: Off-grid three-phase inverters are utilized in remote monitoring and surveillance systems, such as security cameras, environmental monitoring stations, and wildlife tracking systems. They provide a reliable three-phase power supply for running the monitoring and communication equipment in isolated or off-grid locations.
