Choosing the Right Battery for Your 850VA Inverter

Choosing the Right Battery for Your 850VA Inverter: Most homes use simple appliances like 3-4 fans, 4-6 LED lights, a TV, which you can easily run on an 850Va inverter. But how long you can run this load will depend on the battery. That is why it is very important for you to choose the right battery for an 850Va inverter.

If you buy a small battery like 80Ah, 100Ah, then you may not get much battery backup. If you buy a bigger battery like 250Ah, 300Ah, then the inverter may not be able to charge it fully. That is why only by installing a right battery with an 850Va inverter, you will get the right battery backup and your battery will also be charged properly.

Choosing the Right Battery for Your 850VA Inverter

The 850Va inverter comes in 12V, hence you should install only one battery on this inverter, whether it is 100Ah or 150Ah.

How much Ah should the battery be?

How much Ah battery you need will depend on your requirement. For example, if you want to run a 250W load for about 4 hours, then a 150Ah battery can run this load very easily. But in many places, power cuts last for 6-7 hours, so you will have to install a 250Ah battery to run a 250W load for 6-7 hours.

Inverters of some companies support batteries up to 250Ah. But an 850VA inverter can run a load of up to 400W, so if someone wants to run a 400W load for 5 hours, he has to install 1 battery of 300Ah.

You will find 300Ah batteries of many brands in the market, but this battery takes about 15 hours to charge. That is why if there is electricity in your house for 15 hours, then you can use this battery. If there is electricity for less than 15 hours, then you will have to charge these batteries by installing solar panels.

How many solar panels are needed for the battery

To charge a 150Ah battery with a solar panel, you need a 300W solar panel. If you want to run a load with the solar panel during the day, then install a solar panel with 25% more capacity than the load you want to run. For example, to run a 400W load, install a 500W solar panel and another 300W solar panel to charge the battery. In this way, you will have to install 800W solar panels.

Which battery to choose?

Currently, all 850VA inverters in India support only tubular batteries and you should use this battery. But if you want to install a good battery, then you can use a lithium battery, which can be charged very quickly. You can use a 12V 150Ah lithium battery instead of a 300Ah tubular battery.

You can also get 12V 200Ah lithium battery in the market. If someone wants to run a 400 watt load for about 6 hours, then this lithium battery will be the best for him.

Lithium battery can be fully charged in about 3-4 hours. But you should buy lithium battery from the same company whose inverter you buy, only then it will work better. Apart from this, inverters with inbuilt lithium battery are available in the market right now, you can use that too.

How to connect 2 batteries in one inverter

Many people want to install two batteries on the same inverter to get more battery backup. If you also want to install two batteries on one inverter, then you will have to install a solar charge controller to charge both those batteries. Only then can you get good battery backup by installing two batteries on one inverter.

In the diagram above you can see how you can install two batteries on a single battery inverter. It is very easy to install. First you have to connect the negative terminals of both the batteries together, then connect the positive terminals of both the batteries together.

After connecting the batteries, the positive wire coming from the inverter has to be put on the positive terminal of one battery. Then the other negative wire of the inverter has to be put on the negative terminal of the battery. In this way, you can put two batteries on one inverter. But by putting the batteries in this way, the life of the battery can be reduced and there may also be a problem in charging both the batteries properly.

conclusion

You can get good battery backup by installing the right battery as per your requirement on the 850Va inverter. If you need a longer battery backup, then you should use lithium battery. Also, before buying tubular battery or lithium battery of any brand, find out about its brand thoroughly whether that brand provides good service in your area or not. Only then buy the battery of that brand, so that you can use the battery for a long time without any problem.
