Comparison of UPS and Energy Saving Mode

Operation Mode Description & Special Feature Possible Application
UPS mode Utility has the highest priority, the TN unit
will operate as an UPS system.

‧ Area with unstable utility
‧ Better performance as compared to conventional UPS (capable of   withstanding heavy load)

‧ Office: computer system, security system, printer, scanner, fax…etc.
‧ Home: personal computer, refrigerator, lighting…etc.
‧ Telecom sub-station
Energy Saving mode Solar energy has the highest priority. Utility
bill can be reduced since the TN unit acquires
energy from the solar panel as higher priority.
Solar panel ->battery bank-> inverter->load (user’s equipment)‧ With additional solar panel. It can be used as individual sub power station (Independent power station)
‧ Area without utility or unstable utility
‧ Cut cost on utility bill
‧ High altitude location or green building: weather station, lighting, hair dryer…etc.
‧Yacht: TV, DVD, radio, air conditioner,
coffee maker…etc.
‧ Vehicle: mobile phone charger, notebook,
electronic pot…etc.
‧ Modified sine wave inverter is a stepped waveform that is designed to have characteristics similar to the sine wave shape of utility power. It is suitable for most household applications, such as notebook, PC, MP3 player, cell phone charger, and digital camera…etc. but may present certain compromises with some loads such as ham radio, microwave oven(with clock), laser printer, motor speed controller, transformer-less charger, and load with high surge demand (capacitance, fluorescent lamp…etc.).
‧ True sine wave inverter is suitable for most AC loads, including all electronic equipment of household, motor related application such as electronic drill, linear and switching power supply used in electronic equipment.
