• New design Luminous inverter with latest technology advances
• Higher efficiency & long backup
• Sine wave Inverter for High efficient power supply
• Advanced battery management to enhance battery life by up to 70%
• Hassle-free battery maintenance with intelligent battery water level sensor, if you use the tubular battery type
• Proprietary FSW technology transformer for high efficiency and long life
• Battery charging commences even at as low as 110V Mains AC
