Watt hours divided by 1000 is equal to kilo Watt hours. Example: 12 volts X 200 amp hours = 2400 Watt hours.

If you use 20 Ah per day the 300 Ah battery is probably good for 5 days. You need to fully, 100%, recharge lead acid batteries. Cycling from 50% to 80% and back will quickly degrade the battery capacity.

A 300 Ah battery operating at 6V (volts) can store 1,800 watt hours, or 1.8 kWh, of DC power. With a 50% depth-of-discharge (DOD) rate to extend the battery life, the 300 Ah battery could deliver 0.9 kWh of daily DC power. Compare this to how many kWh you use everyday.

Exide has also collection of Home Inverter Battery (100Ah to 300Ah) and cost of Exide Home Inverter Battery is Rs….

No Inverter Does Not Raises Power Bills. Because Inverter is converts DC power to standard home AC power. This lets you run AC electrical equipments during power cuts conveniently.

You can do it online in just a few minutes. You can easily compare the price of battery at different stores online, which will help you get the best value for your money. In addition to batteries for inverters, the company offers batteries for UPS, solar applications, E-rickshaws as well.

Usually, you can expect your inverter battery to last anywhere from 5 to 10 hours when it is fully charged. Most inverters show an estimate as soon as they start powering the appliances.

How to choose the right inverter & battery for your home?

1. First understand your Power Requirement. One of the most important factor that you must know before buying an inverter is your “Power requirement”.
2. Find the VA rating of the inverter you need.
3. Know the battery your inverter needs.

UPS vs Inverter: Summary of the Main Differences

	UPS	Inverter
Battery maintenance	No maintenance required	Requiring continuous maintenance
Circuitry sophistication	More sophisticated	Less sophisticated
Protection	Providing protection to load	No protection against line abnormalities provided
Price	More expensive	Less expensive

Well, you do not need a UPS if you already have an inverter to power your PC. However if you wish not to use the PC on the main inverter and wish to use the PC on another plug socket not connected to the inverter then you can use the UPS. But it is not necessary to use both at once.

The main difference is the process of filtering power. Brownouts, flickering power, and power surges won’t always trigger a battery backup, but a UPS filters that power, so devices gain steady and consistent power. While a UPS is 3-4x the cost of a battery backup, they are not all made equal.

Every UPS is rated in VA and Volt . VA is the capacity of an UPS to run peak load and volt is the number of batteries required to connect with the UPS. The battery which is used in UPS application is of 12 Volts. Therefore, it means that a 12 Volt UPS requires 1 battery and 48 Volt UPS requires 4 batteries.

But a UPS will filter that power, which allows a consistent, filtered power supply to the important devices that need to continue running and processing data. They filter the voltage to your device to reduce or eliminate damage to the devices during power issues. The UPS converts AC to DC for charging.

An uninterruptible power supply (UPS), also known as a battery backup, provides backup power when your regular power source fails or voltage drops to an unacceptable level. A UPS allows for the safe, orderly shutdown of a computer and connected equipment.

Generally, the UPS does not require a minimum load to charge its batteries. Once connected to a standard supply of electricity (via input plug or hardwiring), your UPS should charge its batteries regardless of how much load, if any, is attached to it.

There are primarily three kinds of batteries used in UPSs—valve-regulated lead-acid (VRLA), also known as sealed or maintenance-free lithium- ion batteries, and vented lead acid (VLA) (also called flooded-cell).

uninterruptible power supply

While the UPS battery’s main function is to cover the gap between power failure and backup power, it can also serve to make your system more reliable under normal conditions.

Connect the Battery in the New APC UPS Open the battery compartment. Pull the battery out half way. Connect the Red Battery Wire to the + Positive battery terminal. Push the battery into the compartment and re-install the cover.
