How To Find The Best Solar Generator

When we first cleared the land to build our off grid home back in 2016, we started with one of those small 700 watt Moto Master Eliminator Power Box from Canadian Tire that we used to keep our cordless tools charged during the day. That’s about the limit of use for this sized device on a build site. The advanced and much more powerful solar generators of today just weren’t available quite yet and we didn’t own a gas generator… yet.

Next we bought a 3250 watt Champion generator that would run most of the day nonstop to power our compound miter saw, skill saw, charge up our cordless nail gun and recharge the cordless tools. You can check out our entire off grid tool list here. 

While we did indeed cut a lot of lumber using that gas generator, it would have been so much better to have a power delivery system that met certain criteria…

  1. Silent
  2. Draws power only when a tool trigger is pulled
  3. Continuously recharged by the sun while still operating
  4. Portable enough to bring home to recharge for the next day

Fast forward to today and a lot has changed in battery technology since then. Now we have solar generators that can serve as the electrical backbone for an entire build site for several consecutive days. Best of all, it can then be used to power the home afterwards. At last we have a reliable, portable, silent, fully rechargeable and ample power supply for every off grid enthusiast, homesteader, camper or cabin builder. 

Welcome to the world of Solar Generators!

Introduction To Solar Generators

If you’re interested in off grid living or perhaps building your own off grid home, you already know that one of the biggest challenges is finding a reliable and sustainable source of power during and after your build. You never want to depend on the grid, which can be unreliable, expensive, or just plain unavailable in remote areas. You also don’t want to rely on fossil fuel generators, which are harmful to the environment, require ongoing maintenance, costly fuel and generate excess heat/noise.

One of the best solutions is to use a portable solar generator. The concept of a portable solar generator is very similar to the gas generator we’re all familiar with.

However, they run on electricity instead of gas or propane. Think of a portable solar generator as a compact version of a full scale rooftop solar system all rolled into one or two components.

Typical full scale off grid solar systems consist of permanently mounted rooftop solar panels, a wall mounted charge controller, a wall mounted inverter, and a separate enclosure to store the batteries. All of these components are separate from one another and connected by several thick copper cable runs, fuses, disconnects and system monitoring components/computers. 

We currently have three solar panels installed on out roof and the battery bank, inverter and charge controller are all in the loft. These are the solar panels on the off grid cabin.

This is our charge controller, inverter, and battery bank.

A portable or semi-portable solar generator consists of only the main solar generator assembly and solar panels which are optional. 

So how exactly does a solar generator work? What are the different types and features of solar generators? And how do you choose the best solar generator for your off grid living needs?

In this article, we will answer these questions and more. We will also compare some of the top solar generators available on the market today and give you our recommendations. By the end of this article, you will have a better understanding of what a solar generator is, how it works, and which one to buy for your off grid living needs.

What is a Solar Generator and How Does it Work?

Unlike the larger permanent solar system the portable solar generator consists of just two components. The first is the main assembly which houses the battery bank, charge controller, inverter, the monitoring systems, all of the cabling and a display all in one.  This is the EcoFlow Delta Portable Power Station

The only other component required to make this a self sustaining energy system are solar panels that are used to recharge the solar generator.

The best part is that man of these systems like the EcoFlow are expandable by adding on

additional battery modules

to increase the systems overall energy storage capacity.

However, portable being the key word these solar generators can also be easily moved, and recharged by plugging into a typical wall socket. Meaning, you can load it into a vehicle to take it back home (or wherever) at the end of a build day or camping to recharge it, and bring it back the next day fully charged. 

Here’s a quick refresher of the components that make up the solar generator. 

The solar generator works like a solar system by following these steps:

  1. The solar panels capture sunlight and convert it into DC electricity or the solar generator can be recharged using AC power from a wall socket.
  2. The DC electricity flows from the solar panel(s) to the battery through a charge controller, where it is stored and continuously monitored/regulated.
  3. The stored energy in the battery can then send the DC electricity to an inverter, where it is converted from DC into AC electricity.
  4. The AC electricity flows to the appliances and devices, where it is used to power them.

What are the Benefits of Using a Solar Generator for Off Grid Living?

Using a solar generator for off grid living has many benefits from convenience, flexibility, low maintenance, and cost-effectiveness. The solar generators of today can easily provide enough power to sustain a small off grid home for several days. And unlike a full sized roof mounted solar system, a solar generator does not require installation, wiring, and little to no maintenance. It’s small, lightweight, and easy to relocate making it perfect for build sites as well as weekend camping getaways.  

Here are some additional benefits of a solar generator for off grid living:

Clean and renewable energy

Low maintenance and easy to use

Cost-effective in the long run

Reliable and versatile

What are the Different Types and Features of Solar Generators?

There are two main types of solar generators and it really only comes down to size/portability.

Portable Solar Generators

Portable solar generators are small, lightweight, and easy to carry and set up. They can be used anywhere and anytime you need power, such as in off grid cabins, tiny homes, RVs, or camping sites. They can power a few appliances and devices for a short time, such as laptops, phones, lights, or fans. They do not require any installation, wiring, or maintenance, but they depend on sunlight and have a limited capacity and performance. Some examples of portable solar generators are the

EGO Power+ PST3042 Nexus Portable Power Station, J

ackery Explorer 1000, the Goal Zero Yeti 1500X, and the EcoFlow River Pro.

Stationary Solar Generators

Stationary solar generators are larger, heavy, and more difficult to move. They are usually installed and wired directly to an electrical panel. They can power many appliances and devices for a long time, such as refrigerators, air conditioners, or circular saws. They require some installation, wiring, and maintenance, but they are more reliable, consistent, and powerful than portable solar generators. Some examples of stationary solar generators are the Point Zero Energy Titan Solar Generator, the Inergy Apex Solar Generator, the Humless Home Power 6.5K Solar Generator, and the
