Yes -- in the Indian market, home inverter and home UPS refer to the same type of device. Okaya's Advanced Home UPS (ATSW series) functions identically to what most people call a home inverter. The UPS term reflects the 10ms Fast Mode Switching (Smart Phase Match Switching) that makes the transition from grid to battery -- and back -- fast enough that appliances like computers, routers, and refrigerators do not restart or reboot. This is a key advantage of Okaya's ATSW range over older inverters with slower transfer times.
Advanced True Sine Wave (ATSW) output means the inverter or home UPS generates power with the same smooth waveform as grid electricity. This is essential for sensitive appliances such as laptops, computers, variable-speed fans, refrigerators, and medical equipment -- they run safely, quietly, and without performance degradation on True Sine Wave power. Okaya's ATSW series uses SMT (Surface Mount Technology) and SMD (Surface Mount Device) processes to deliver compact, reliable, and consistent sine wave output across all load conditions.
To find the right VA: add up the wattage of all essential appliances and divide by 0.8 (the standard power factor). Okaya's ATSW Home UPS range covers:
All models carry a 36-month warranty and Advanced True Sine Wave technology.
Super Intelli Charge is Okaya's fast-charging technology that charges batteries 15% faster than conventional inverters using a Boost to Float mode, achieving 60% charge in significantly less time after a deep discharge -- important when power cuts are frequent and long.
The specially designed EI Core minimizes heat and power loss with at least 20 to 25% lower watt loss compared to standard transformer cores, which increases load handling capacity and extends the operational lifespan of the home UPS. Together, these features make Okaya's ATSW range more energy-efficient and longer-lasting.
The ATSW 950 (700 VA) and ATSW 1175 (925 VA) are suited for lights, fans, and small appliances. A refrigerator typically needs at least 1150 VA, making ATSW 1400 or ATSW 1700 the right models.
Okaya's Advanced Home UPS also supports over 100% load for short durations to handle the startup surge of motorized appliances like mixers and fans.
For ACs, water pumps, or commercial-grade loads, Okaya's Hi-Capacity UPS range (starting from ATSW 3050 at 2500 VA) is the appropriate choice. Always match the inverter VA to your total load for best performance.
Okaya ATSW Home UPS models include:
These protections safeguard both the connected appliances and the inverter itself during abnormal operating conditions, making Okaya's home UPS range reliable for long-term daily use.
