Not so long ago, the inverter battery was predominantly used in commercial applications such as power stations and the automotive industry for backup power. https://www.renogy.com/inverte....rs/battery-inverters
Nowadays, we see more and more private households utilizing this convenient energy source as a solution for power cuts or where mains electricity is not accessible. As a leading supplier of lead-acid batteries in India and many other countries, we understand domestic customer requirements more than most. As the national grid supply in many countries is often unpredictable, the general populace has a need for a long-lasting, fairly priced energy storage product that won’t let them down.

Batteries for this sector have to be reliable rugged and sufficiently abuse-resistant without posing a public safety hazard. Batteries release their stored energy as direct current (DC) which is incompatible with the alternating current (AC) delivered by the mains supply. Alternators and transformers are used to convert DC to AC making the power supplied by the battery compatible with the mains feed into a building and run the various electrical appliances which use the AC supply. They are used in industries where an uninterruptible power supply (UPS) is needed, such as residential homes and housing units. There are many countries even today where the general populace still relies on battery backup for protection against a failure of mains power.
