Off-Grid Solar Cabin Kit – Everything You Need to Know


As our world grows more eco-conscious, we find ourselves searching for ways to decrease our environmental impact and move towards more sustainable living. An off-grid solar cabin kit allows us to do just that in a remote, natural setting.

Whether you’re looking to reduce your carbon footprint, cut energy costs, or enjoy the independence of generating your own power, this guide will provide you with everything you need to know about off-grid solar cabin kits.

What Is an Off-Grid Cabin?

An off-grid cabin is a self-sufficient dwelling not connected to the electrical grid. One that’s connected to the electric grid would be an on-grid home.

So, how does an off-grid cabin stay powered up? There are several ways cabins can generate their own power, but solar is one of the most common and straightforward to set up. Since cabins (especially off-grid cabins) are generally small, there’s a smaller electricity need that makes it easier and cheaper to supply power than it would be to power a large home.

How Do Off-Grid Solar Cabin Kits Work?

Off-grid solar cabin kits utilize photovoltaic (PV) panels to convert sunlight into electricity, which is then used to power the cabin. These panels are typically mounted on the roof of the house or may be mounted on the ground. The power the panels generate gets sent to a battery bank where the energy gets stored for use, immediately or later. 

Solar panels generate electricity in the form of DC (direct current). An inverter can convert this electricity to AC (alternating current), which is used by most household appliances. Other times, appliances may be able to run using 12V electricity, in which case the solar power generated and stored in the battery bank can flow directly to the appliances without needing to be inverted first.

Having appliances that run on 12V electricity is helpful in this case because some energy is lost by needing an inverter running all the time. These special energy-efficient appliances can help your solar power go further.

Solar panels generate power when the sun is shining in the sky. Fortunately, with proper preparation, they can still perform well during the winter months. However, relying on sunlight, they won’t generate power at night and may only generate a small amount when cloud cover is heavy. 

It’s necessary to store electricity in the batteries for use at night and on dreary days to prepare for times when your solar panels aren’t producing as much energy, 

What Do Off-Grid Solar Cabin Kits Include?

Off-grid solar cabin kits typically contain everything you need to get your cabin up and running. This includes PV panels, a battery bank, a charge controller, an inverter (if required), a battery management system, and all the necessary wiring and mounting equipment.

It’s important to ensure you have all the necessary components for your specific energy requirements, so make sure to review what you’re purchasing carefully and ensure that all of your equipment is compatible.

PV Panels

PV solar panels aren’t necessarily included in a balance of system, but they’re an essential part of an off-grid solar cabin kit. These panels are typically mounted on the cabin’s roof to get the most access to the sun’s energy for capturing, storing, and use.

Solar Battery Bank

The solar battery bank is where all the energy generated by the PV panels gets stored for later use. The size and type of batteries included in the kit will depend on your specific energy needs. The EcoFlow DELTA Series Solar Generators have impressive off-grid electricity storage options that range from smaller cabins to larger, more energy-intensive homes – and they include a solar panel (or solar panels).

Charge Controller

A charge controller is necessary to regulate the energy traveling from the solar panels to the battery bank. If your solar array feeds a battery bank, you’ll want one to prevent electrical surges that can damage your battery and shorten its lifespan.


You’ll likely need an inverter to convert the DC power from the panels into AC power, which is used by most household appliances. If your setup doesn’t include one, you may need to purchase a separate inverter suitable for your needs.

Battery Management System

A battery management system performs essential functions such as keeping the batteries from overcharging and undercharging. It also helps optimize efficiency and performance.


Other accessories needed to complete your kit may include cabling, wires, fuses, switches, outlets or breakers, a grounding rod, mounting hardware for your solar panels, or anything else you might need for your specific setup.

What Are the Benefits of Installing an Off-Grid Solar Cabin Kit?

When you install an entirely off-grid solar cabin kit, you gain several advantages that allow you to create and live off your own self-produced solar energy. Let’s delve into some of the benefits that this provides.

Energy Independence

One of the main benefits of installing an off-grid solar cabin kit is energy independence. You’re no longer reliant on external sources of power, which gives you the freedom and flexibility to live in remote locations without sacrificing modern conveniences.

Reduces Energy Costs

By generating your own electricity, you can save money on your electricity bills, which is especially beneficial for those living in areas with high electricity rates. Remote locations where cabins are often found can be challenging to connect to traditional electricity.

Lower Carbon Footprint

An off-grid solar cabin kit also helps reduce your carbon footprint, as solar energy is a renewable power source that doesn’t produce greenhouse gases or air pollution during operation. By using PV panels instead of traditional electricity, you’re choosing a more environmentally friendly option.


Solar energy is a renewable resource, unlike fossil fuels such as oil or gas. It’s a sustainable solution for powering your off-grid cabin in the long term. It won’t deplete finite natural resources for future generations.

Low Maintenance

Another benefit of a solar off-grid power system is that it requires minimal maintenance. Once the system is installed, there are few ongoing costs or minimal annual maintenance needs.

What to Consider When Choosing an Off-Grid Solar Solution for Your Cabin

Before purchasing an off-grid solar cabin kit, there are a few factors to consider to ensure you choose the right solution for your specific needs. Here are a few things to keep in mind:

Cabin Size

The size of your cabin will determine how much energy you need to power it. A smaller cabin may only require a smaller system, while a larger cabin with more appliances and electronics to power will require a more extensive system. 

For a smaller cabin size, you might opt for something like the EcoFlow DELTA 2 + 220W Solar Panel or EcoFlow DELTA 2 Max + 160W Solar Panel. If you have a larger cabin, you might opt for EcoFlow DELTA Pro + 400W Solar Panel, which even has an expandable capacity all the way up to 25kWh.

Sunlight Exposure

The amount of sunlight your cabin receives will also play a role in how much electricity your system is able to generate. If your cabin is heavily shaded, this could impact your electricity generation. If your cabin gets many hours of direct sunlight daily, this is great news for your electricity generation capabilities.

Energy Requirements

Consider what appliances and electronics you plan to power with your off-grid solar system. Doing so will help determine the size of the solar power system and the different components needed for your specific energy requirements. It’s also essential to consider any future needs or potential expansions when choosing a system.

For example, a “tiny home”-style cabin with only a couple of appliances won’t need much solar power behind it, but a larger build might need a lot more power to keep it running, depending on what you plan to power. 

You’ll need to consider things like AC output, storage capacity, and more when choosing your ideal system. Make sure that you have the appropriate space and solar generation capabilities to accommodate your needs, as well as ensure that your gear is up to the task.
