It enables homeowners to become independent of the traditional electricity networks. While it also saves money on your electricity bills. Comprehensive off-grid solar systems come with batteries and all the necessary components to help you break away from the utility companies. Here is all you need to know about the off grid solar system packages with batteries. So, let’s quickly dig down to the topic!

What is meant by Off Grid?

So, what do you mean by Off Grid? The meaning of Off Grid is nothing but getting detached with utilities such as cables, pipes, wires, etc. You do not depend on gas or electricity to fulfil your home requirements. You produce your energy to run your home or office. Off Grid living is even getting encouraged with the rise of renewable energy such as wind and solar energy. But producing energy with such systems requires space, so it might be a little difficult in dense areas. Whereas, it is easy to produce renewable energy in suburban as well as rural areas.

Is It Possible to Go Off-grid with Solar Panels and Batteries?

Now, let’s understand if it is possible to go Off-Grid with solar panels and batteries. So, the answer is yes, it is possible, if you feel sure that you would be able to produce the needed electricity. During summer it is quite easy to produce electricity with solar panels and batteries, but it might be difficult during winter and rainy days. If the sun would not reflect enough heat, you would not be able to produce energy with it. In order to produce electricity during these days, you will need to add more solar panels.

How Many Batteries and Solar Do I Need to Go Off-Grid?

The number of batteries and solar needed to go off-grid depends on your power utilization. But do remember to own a solar panel larger than your need, if you are thinking of going off-grid. For example, if you are living in a 3 bedroom home, then you might need 10 solar panels. Let’s understand the number of solar panels required for different solar system with the help of a chart:

Solar panel system

Number of solar panels

5.25 kW

15

4.2 kW

12

3.5 kW

10

2.8 kW

8


This means that for preparing a 5.25 kW solar panel system, you will need 15 panels, respectively.

Meanwhile, you should choose a battery with enough capacity to store your remaining power. For example, in general, it is said that an 8kW storage battery is charged by a 3.5 kW solar panel in 1.1 days. But, if we talk about the reality, it takes almost 2 or more days.

Advantages of Off Grid Solar System

Now, we will understand some of the advantages of an off grid solar system with the help of some questions that people frequently ask about it.

1. Can you add batteries to an existing off-grid solar system?

The answer to "can you add batteries to an existing off grid solar system" is yes. There are chances that you might require some rewiring. You might also need to replace your inverter, in case it is not suitable.

2. How long will a 5kWh use battery power a house?

A 5kWh battery could power a house for approximately 10 hours, in case of using it for a few appliances including fridge, TV, etc. Further, if you use it for any heavy duty appliances then it might discharge very quickly.

3. How long do off-grid solar batteries last?

Off grid solar batteries last somewhere between 5 to 15 years. Among all the solar batteries, lithium ion batteries last for the longest and i.e. 15 years. Solar batteries life also gets affected with its maintenance, environment, cycle life, depth of discharge, installation, battery type, etc.

4. What happens when off-grid solar batteries are full?

When the off grid solar batteries are full, it could overcharge the system. When a solar system is overcharged, it can crucially damage the life of the battery. Whenever you find that the solar batteries are fully charged, the charge controller and inverter need to be put in to mitigate risks by handling excess power.

Final words

Firstly, it's important to know how this Off Grid Solar System works and why you need it. Off Grid System works as a stand alone power generation system. So, unlike the grid connected solar systems, it's totally independent of power grids and does not require any cabling. But before purchasing a solar system you should first make a complete study of your consumption requirements. You also need to know what loads you are going to run on solar energy.

We recommend purchasing BLUETTI solar batteries for your off grid convenience, as they are suitable and best in every manner.
