An off-the-grid solar system is an alternative to the grid-tied solar system. Off-grid solar power systems are designed to serve the power needs of mid-to-large houses in remote areas.

It has no connection to the utility grid and must generate all the electricity necessary for your home. It is also known as a stand-alone power system(SAPS).

The term off-the-grid means living sufficiently without public utilities. The electrical grid is a utility, it is designed for areas with little access to electricity due to a distant population.

Because an off-the-grid system is not connected to the electricity grid, it needs battery storage. Also, an off-the-grid solar system must be designed to generate enough power throughout the year. It must also be designed to meet the home’s requirement, even when there is no adequate sunlight.

Due to the high cost of batteries and inverters, off-grid systems are more expensive than on-grid systems. There are usually only needed in remote areas.

However, batteries are getting cheaper and there is a growing market for off-grid solar systems in cities and towns.

Once all your appliances have gotten enough power, any excess power will be sent to your battery bank.

Your appliances will draw power from your battery bank when your solar system is not working.

There are days in the year when there is low sunlight and the batteries are low on charge. For those times, you will need a backup power source, like a backup generator.

The size of the backup generator should be able to power your appliances and charge the batteries at the same time.

Equipment Needed for an Off-The Grid Solar Systems

  • Solar charge controller 
  • DC disconnect 
  • Off-grid inverter 
  • Battery bank 
  • Backup power source(optional) Advantages of Off-Grid Solar Systems 
  • If you live in an area that is prone to blackouts or without access to electricity, the off-the-grid system gives you the security of constant power. Even if something goes wrong with the grid, your electricity will still function.
  • No electric bill. Because you do not use electricity from the grid, you won’t be charged the usual monthly electricity bill. 
  • Off-the-grid solar systems are easier to install, as opposed to the traditional grid systems Before you purchase an off-the-grid solar system, there are certain things you need to know to pick the best one for your home. Installing the wrong system will lead to serious consequences. The electric output may not match what your appliances need. In getting an off-the-grid you must know how much power you want to create and store. You can determine this using a load list calculator. You need the time to evaluate your power, so you can ensure you install a solar system that meets your needs now and in the future.
