Inverter Battery कैलकुलेटर
गणना करें required inverter VA और battery Ah from lights, fans, TV load, backup अवधि, battery voltage, power factor, और efficiency.
फॉर्मूला समझाएं
Inverter VA = load watts / power factor; Battery Ah = load watts x backup hours / (battery voltage x efficiency)Inverter sizing converts real load watts into VA का उपयोग करके power factor, while battery sizing estimates amp-hours needed after inverter और battery losses.
स्टेप-बाय-स्टेप उदाहरण
- 1Add fan, light, और electronics loads to get कुल watts.
- 2Divide watts by selected power factor और add reserve margin for inverter VA.
- 3Multiply load by backup hours to get watt-hours.
- 4Divide watt-hours by battery voltage और efficiency, then add a reserve margin for battery Ah.

अक्सर पूछे जाने वाले प्रश्न
Divide कुल connected watt load by inverter power factor. This कैलकुलेटर assumes 0.8 और adds reserve margin.
Multiply load watts by backup hours, then divide by battery voltage और efficiency.
Reserve margin helps handle starting surges, inverter losses, battery aging, और real-world load variation.
This कैलकुलेटर is intended for common घर loads like fans, lights, और TV. ACs need separate surge और compressor-load sizing.
