Why is a Solar Generator is Beneficial for Off-Grid Living?

Before we offer our top three picks for the best solar generators for off-grid living, we are going to explain why a solar generator can be so useful in the first place.

What is a Solar Generator?

As mentioned previously, a solar generator is a self-contained piece of solar equipment that can act as a complete solar power system when it is paired with one or more solar panels.

Essentially, these compact pieces of equipment offer many of the same benefits that you would get with a gasoline-powered generator, but they do not need to burn fuel or emit noxious fumes. Since they do not have any moving parts, they also generate very little noise, which is another reason why they can be used indoors, as well as outdoors.

A solar generator will feature a rechargeable, deep-cycle battery that can store power that is generated by solar panels. They also feature a built-in inverter, which means you can use that stored solar electricity to supply power to your portable electronic devices, as well as electrical appliances. Depending on the specific model, they also tend to have a wide range of built-in output ports, which means you can plug your electronics directly into the solar generator.

Why Are Solar Generators Helpful for Off-Grid Living?

Given that solar generators allow you to supply power to various appliances and electrical devices, they are extremely useful for anyone that does not have access to a traditional electrical grid. The fact that solar generators are also designed for portability is really important, as it means you can take power with you wherever it is required.

Even if you were running a traditional solar power system to satisfy most of your power requirements, adding a solar generator would give you more flexibility. You could bring power with you wherever you needed it around your property. For example, if you needed lights and the ability to run power tools in your workshop, you could use your solar generator as a source of power.

Solar generators are so portable that many RV enthusiasts and campers will take a solar generator with them on their off-grid adventures. Not only are they portable, a solar generator can act as your emergency power source in the event that your primary power source fails.

Solar Generator Alternatives for Off-Grid Living

If you do not value portability and are just looking for a way to satisfy some of your electricity needs with solar power, you may want to consider a more fixed solution. Fortunately, there are many alternatives to a solar generator that allow you to store and use electricity sourced from sunlight.

One of the best ways to outfit your off-grid home or cabin with a reliable solar power system is to invest in a Complete HBK Off-Grid Solar Kit.

These simple kits contain everything you need to build your own solar power system, including a massive deep-cycle battery bank, a powerful inverter, an efficient charge controller, multiple solar panels, and all of the cables and connectors required to wire everything together.  

In most cases, your money will go further with a HBK Off-Grid Solar Kit because the components do not have to be contained within a single unit. This means they are easier to manufacture, as they are not restricted by size.

For example, take this OGK-10 Complete Off-Grid Solar Kit, which features 6x 200W solar panels, a 6,000W 120/240V inverter, and 15.8kWh of storage capacity!

You simply could not fit components this large or this powerful into a solar generator. If you were living off-grid full time, it might be a better option for you to run an off-grid solar power system, as well as a solar generator; however, expandable solar generators, like the EcoFlow Delta PRO can operate as both.

Basically, the choice is yours. Consider your own budget, preferences, power needs, and how reliant you will be on solar power to determine which option is the best for you!
