Diesel / Petrol Generator is a total different concept. In Diesel / Petrol Generator you create the Electrical Energy by means of Diesel & Petrol. You have to start the Generator manually by pressing Button or pulling Chord. It gives heavy Noise & Smoke. It is not Automatic as needs heavy Maintenance. The approximate per hourly cost of this Generator is Rs.15/- to Rs.25/- Whereas an NOVA-PRO Inverter [Electronic Inverter] is fully Automatic i.e. it starts automatically on Power failure and stops after the power resumes. It is Pollution free, smoke & noise free. NOVA-PRO Inverter requires very low maintenance. Hence NOVA-PRO Inverter is very cost effective as its per hour cost is 50 paise to 2 rupee.

This ensures that the NOVA-PRO Inverter is in series to the load. Hence during Power supply the Switch / Switches get the MSEB Phase connection via NOVA-PRO Inverter and upon Power failure NOVA-PRO Inverter supplies the Phase to the corresponding points within fractions of seconds thereby giving an uninterrupted supply.
