How many Ah inverter battery do I need for Home?

Ever had an experience when you had to remain without electricity for a long time as compared to your general lifestyle? For circumstances like this, you may get a backup that wouldn’t let you face any such trouble. A generator may crop in your mind as a solution. But a few disadvantages of it like making a lot of noise, generation of a lot of pollution, space-consuming, a lot of maintenance, etc. can’t be overseen. Therefore, instead of a generator, you may get an inverter battery.

An inverter battery is a device that provides a small amount of current consistently for a longer period of time. They even do not get discharged for a much longer time. The performance and life of an inverter depends on its battery. As such, a battery is a critical and main component of an inverter battery. It is also known as UPS batteries. It could be either a lead-acid rechargeable battery or a lithium-ion rechargeable battery used with a home inverter.

But, how would you decide what capacity inverter battery you need to get that would be enough to run your house’s load? Well, there are three steps that are actually involved in this decision.

Step 1: Load Calculation

The first and foremost step that you need to take is to calculate the load of your house. In general, the following are the appliances found at a home:

Appliances

Quantity

Average Consumption (in Watt)

Lights

12

20W*12 = 240W

Ceiling Fans

5

70W*5 = 350W

Water Pump

1

746W

Air Conditioner

1 (1.5Ton)

1800W

Refrigerator

1

250W

Mixer

1

200w

Geyser

2

2000W*2 = 4000W

Total

7,586W

Now, all you need to do is to calculate your total load. For this, you may use the load calculator tool by Loom Solar: https://www.loomsolar.com/blogs/calculator/load-calculator

Therefore, Maximum Power Consumption: It depends on the hours your appliances run. For instance, if they run for two hours, then just multiply the total consumption with two. Here, the result will be (7,586*5 = 37,930)

Regular Power Consumption: It actually depends on the time you run your average quantity of regular appliances at the most. For instance, the above table shows the regular power consumption of an hour each appliance.

Minimum Power Consumption: This depends on the minimum quantity of normal appliances used at your home. For example, generally, a 2BHK home may use 3 lights and 2 fans, which can be calculated with multiplying their total consumption with the number of hours they are used. In this case,

20W*3 = 60W

70W*2 = 140W, which would sum up to a total of 200W.

Step 2: Inverter Selection

If we are talking about inverter battery, it obviously isn’t possible that an inverter won’t be mentioned. For a complete selection of a perfect inverter battery, you also need to select an inverter. Thus, the second step comp-rises of nothing, but the selection of an inverter. Simply stating, your inverter should be capacity twice of your load. Stating this is a simple formula:

Inverter Capacity = 2 * Regular Power Consumption

For instance, in the case above mentioned,

Inverter capacity = 2*5590 = 11,180W or 11.1kW (approximately)

Step 3: Battery Selection

The final step in the selection process of an inverter battery would be the selection of a battery. Now, the battery voltage depends on the inverter’s capacity. For instance, your requirements will be of following:

Inverter capacity of 700VA = 12V Battery.

Inverter capacity of 1kW = 24V Battery

Inverter capacity of 2kW = 24V/48V Battery

Inverter capacity of 3kW = 48V Battery

Inverter capacity of 5kW = 48V Battery

Inverter capacity of 7.5kW = 96V Battery

Inverter capacity of 10kW = 120V Battery

Conclusion

You must have by now know what capacity inverter battery you would be require for your home if you have done the calculations right. But, if you still have any doubt, you may contact Loom Solar and the company would happy to be of any help to you!

Now a days we rely on coal for electricity but now we emphasized on solar panel, lithium battery for electricity.
