What Is An Off Grid Inverter And Who This Is For
If you are thinking of installing solar power into your home, there are terms and ways with which you need to familiarize yourself, and one of the terms that you will often hear is a power inverter for solar.
There are many ways on how a solar panel convert’s solar energy into electricity, for machines and other equipment, direct current of DC is needed to replace the power stored in the battery.
But if you want to use solar energy at home to replace the traditional electricity coming from the grid, you need an AC or alternating current. The only way for you to be able to change direct current to an alternating current is by using an inverter.
There are different kinds of inverters, and even though they all convert DC to AC, and they produce the same outcome, they still work in different ways.
An off-grid inverter involves both battery storage and solar panel so that you can get electricity in your home from these two sources.
Typically, the off-grid inverter gets power from the solar panel to sustain your home electricity in the morning while it uses the battery at night.
Off-grid inverters control the energy flow, and it controls both powers, DC and AC, which is then used to replace the traditional electricity in your own home.
This type of inverter is perfect for those who want to use solar energy to power up their homes. We all have different kinds of appliances, such as TV, kitchen appliances, washing machines, and the lights that we use all around our house.
That alone takes a lot of energy to be able to light it up, especially if you want it on 24/7. This is why an off-grid inverter transforms and stores energy that you can use day and night, to make sure that you have all the appliances working without spiking up your electricity bill.
How Does It Work
Solar inverters can convert direct current or DC electricity into alternating current or AC, depending on what you need to use in order to light up your home or keep a machine working.
Inverters are components of solar electric systems because solar panels create DC electricity, and most appliances that are used in offices or homes run through AC voltage.
The solar energy is converted to electrical energy by using photovoltaic cells, and depending on its size, a photovoltaic system could have either a single or multiple inverter.
The energy is stored in the battery during the daytime, and they are used at night or on demand. This system is made to use solar energy for home and office by using an inverter.
An inverter, like an off grid pure sine wave inverter, converts direct current or DC output of a solar panel into alternating current or AC output, which is known as a utility frequency because it is the voltage that appliances use. It can be used in a commercial electrical grid or by an off-line electrical one.
There are two types of systems, a grid-tied, one connected to the grid, and an off-grid, one disconnected.
Even though the inverter function is the same, which is converting direct current into alternating current, off-grids and grid-ties use different kinds of inverters.
If you are planning to use solar energy for your home, you will need an off-grid converter as it produces the voltage that is needed to keep your equipment working and to light up your home, plus it can store energy in a battery, and it can also convert energy directly to replace the traditional electricity.
What Are The Different Types Of Off Grid Power Inverters
There are two types of off grid solar inverters: Pure Sine Wave and Modified Sine Wave that usually vary in three aspects, to wit: quality output power, compatibility and price.
Dealing with the quality of the power output by these off grid inverter, power quality coming from pure sine wave is cleaner.
As these two types are said to be the measurement of AC output power quality, it is said that the output power quality of pure sine wave is potentially better than or as good as that of power grid.
With this, it is presumed that pure sine wave offers higher quality output than the modified one.
It is said that the type of off grid inverter that has higher quality output is more recommendable even if it is relatively more expensive.
Aside from that rationale, almost all appliances will work with this type of inverter.
Another reason why the modified sine wave is cheaper than the other is that it causes certain damages and issues to certain appliances.
The pumps and motors in a refrigerator, for an instance, tend to burn out quicker and compressors run hotter causing damage to the appliance.
Aside from appliances, modified sine wave may also cause damage to sensitive electronic devices.
The usual result of this type of inverter to televisions are lines in the screen and buzzing sounds thereby resulting to reduced quality of video and audio. Some devices won’t work totally with this inverter.
However, you can still choose modified sine wave over pure sine wave because it is less expensive provided that you are sure that this will work with device or appliance.
Aside from these types of inverter, you can also install a pre-wired power center that includes an inverter, charger, remote control and circuit breakers together with Battery monitor and suppressors.
Advantages And Disadvantages Of Off Grid Inverters
The basic advantage of an off grid inverter is the independence in energy. Other benefits from this technology is the stable power supply through power outrages as well as reduced electricity bills even in most remote areas while conserving the environment making it cleaner and greener.
At times of calamities, communities connected to main utility grid run out of power supply. This power shortage or outrage may cause damages in appliances.
It may also result to loss of income if your business primarily relies to use of electricity.

Choosing the right inverter for you is easy. To start, you need to estimate the power that you need. You can do a simple calculation to know which off-grid inverter is needed.
If you do not have a grid connection, and you rely on your own off-grid system, the pieces of equipment that are needed for it to run are two fans (around 80 watts each), two tube lights (60 watts each), one CFL (15 watts) and one television (120 watts).
You can calculate the power that you need through this formula [(2 X 60) + (2 X 80) + (1 X 120) + (1 X 15)] = 415 Watt. Then you will have an idea about the off-grid inverter that you need to test.
It is also important to know your off-grid inverter capacity. The total power that you need should be the capacity of the inverter. So, if you need 415 watts of power, then you need an off-grid inverter that can supply that.
Inverters come in VA power, so you also need to determine the VA power that you need by converting watts into VA.
You also need to check which inverter will fit your needs. There are two types of off-grid inverter, and they have modified sine waveform inverter and pure sine waveform inverter.
As tested by experts, it is best to use pure sine waveform inverter because it has many advantages.
Pure sine wave inverter can run all of the home appliances effectively and efficiently. They are also known to be durable, plus they can keep your appliances safe.

To test and determine which off-grid system is most suitable for your home, you can calculate your usage patterns and your electrical loads.
By assessing your needs, you can pick the right system carefully and honestly, you can also choose the correct size, and it will function without failure.
The size of the inverter that you are going to get should be based on your overall requirements. You will need to use your load calculation because reducing it can result in savings.
Plus, you also need to know how long your generator needs to run to be able to power up your home.
Another factor that was tested to see which off-grid inverter is best is inverter efficiency.
Inverters are efficient when they are used at or near their peak output, and they are usually at nighttime when all the lights are on at home.
Even in the daytime, when it is not the peak of the inverter’s usage, an off-grid inverter should have high efficiency.
Other things that you need to consider is the system’s input voltage and an output voltage that matches the loads.
It is also important to note that many inverters come with monitoring systems. If your inverter detects any issue with the system, the installer will be notified about it, and you can call maintenance to have it checked.
As years pass by, the technology linked to inverters improves, so there are more and more features that are included.
Choosing an inverter for your home is easy, but it raises some questions, and there are things that you need to test to know which ones to get.

Not only will they be able to help you get the right inverter, but they may also be able to help you get the right panel that will match your inverter. After getting the right inverter, you can enjoy your solar energy powered home.
Frequently Asked Questions
What size inverter do I need for off-grid?
Experts say a 3000W solar inverter with battery units is sufficient for off-grid living. The device can run common household appliances, including a 1-horsepower air conditioner, TV, medium-sized refrigerator, LED lights, and oscillating fans.
You can also calculate the appropriate battery solar inverter size for your off-grid home. The process is as straightforward as adding the peak wattage of all electric appliances, gadgets, and devices in your cabin.
For example, suppose you have a 10W clock radio, a 1,500W dishwasher, a 1,000W coffee maker, two 75W electric fans, a 30W desktop computer, a 120W 32-inch TV, and a 700Wrefrigerator. In that case, your off-grid electrical requirement is 3,7700W, making a 4,000W inverter suitable.
How many batteries do I need for a 2,000-watt inverter?
A 2,000-watt off grid micro inverter requires two batteries to store power sufficient for a family living off the grid. However, this figure is only an estimate because batteries have varying capacities and voltage ratings. You must be ready to do the math to know how many batteries of a certain type are enough for a 2,000-watt inverter.
Determine how many watt-hours you will need per day by adding appliances’ wattage ratings and multiplying them by the hours they need to run each day. Let us say you have an average electric consumption of 1,500 watt-hours.
Then, think of how many days you need the battery to store solar energy (about two to five days).
Multiply the daily consumption (1,500 Wh) by two days to get 3,000 Wh. Ideally, the battery’s maximum capacity should be twice this much. Hence, we must multiply it by two to get 6,000Wh or 6kWh.
Proceed to divide the 6kWh by the battery voltage. Suppose you have 24 volts. In that case, 6000Wh ÷ 24 volts is 250 ampere-hours (Ah).
Divide 250Ah by the battery’s amperage rating to get the number of batteries needed for the 2,000-watt inverter system for home units. Let’s say your solar battery’s electrical current is 125Ah, then 250÷ 125A is two batteries.
Is a 48V inverter better than 12V?
A 48V off grid inverter is more efficient than a power converter with a lower voltage rating (i.e., 12 volts and 24 volts). It can run power-hungry appliances, gadgets, machines, and devices without fail.
Experts recommend 48V solar batteries and inverters for households and businesses with at least 3,000-watt power consumption. On the other hand, a 24-volt system is sufficient for those that require 1,000 to 5,000 watts, while a tiny home, camper van, or Class B RV can benefit from a 12-volt inverter.
