A solar generator can effectively power an electric fence, tapping into renewable energy for a dependable, eco-friendly power solution. With a system that can both generate and store energy, this system ensures your electric fence is continuously charged, even off-grid. Solar generators, such as those from the EcoFlow DELTA series, are ideal for remote fencing needs, allowing placement in areas without traditional power.

These generators are not only portable but also uphold your commitment to sustainability by diminishing the need for fossil fuels. They’re designed to provide long-lasting power, ensuring that your electric fence remains operational.

While the upfront cost is notable, the investment is balanced by significant energy savings over time. Integrating a solar generator with your electric fence setup promises both environmental benefits and steadfast security.

Solar-Powered Electric Fences vs. Using a Solar Generator for an Electric Fence

Choosing between a solar-powered electric fence and a solar generator to power your electric fence hinges on your specific energy requirements and operational convenience. The solar-powered electric fence is streamlined for ease of use, whereas solar generators cater to higher energy demands and offer greater flexibility.

Solar Powered Electric Fences

Wondering if a solar-powered electric fence is right for you? Below, we break down what you might expect from one.


  • Cost-Effectiveness: A solar-powered electric fence that operates directly from solar panels without a generator is a more affordable option. The energy from the sun reduces operational costs to nearly zero after installation.
  • Minimal Maintenance: Solar-powered electric fences require little maintenance. They’re also easy to install, making them a great option for those who don’t want to worry about frequent maintenance and inspections. 


  • Requires Adequate Sunlight: The fence’s power output is contingent on real-time sunlight, which can vary throughout the day and by season. This can also be impacted by weather conditions.
  • Unreliable Effectiveness: If your solar-powered fence isn’t getting the necessary electricity to function properly, its effectiveness could be compromised. If continuous functionality is essential to you, this is something to consider.
  • No Energy Storage: Without a generator or battery, there’s no way to store solar energy for use during the night or overcast conditions. This limitation means the fence will only operate when there’s sufficient sunlight, potentially leaving gaps in containment or protection. However, some systems do include a battery to store electricity.

Using a Solar Generator for an Electric Fence

Thinking a solar generator for an electric fence might be more your speed? Here, we cover what you could experience if you go this route.


  • Reliable Power Supply: With a solar generator, your electric fence can function independently of the weather, thanks to energy storage capabilities. The generator stores excess power generated during sunny periods, and with the right setup, you can ensure the fence remains operational during the night or on overcast days.
  • Multifunctional Use: Besides powering the fence, a solar generator can serve as a power source for other needs, such as charging tools and mobile devices, and even supporting some home appliances during power outages. As a result, solar generators are a very versatile option.
  • Eco-Friendly: Using a solar generator is a green solution that decreases dependence on non-renewable energy sources. This method contributes to reducing the overall carbon footprint and aligns with sustainable living practices. Because you can use a generator for other purposes in addition to powering your electric fence, this option has the potential to reduce your carbon footprint more than a solar-powered electric fence would.
  • Scalability: If your power needs increase, solar generators can often be scaled up by adding more panels or batteries, providing a flexible system that grows with your demands. Just make sure all of your gear is compatible! 


  • Higher Initial Investment: The upfront cost of a solar generator setup is typically higher than a solar-powered electric fence. However, as it can provide more electricity for other uses, this may be a worthwhile cost depending on your needs.
  • Maintenance Requirements: While not excessive, solar generators do require some maintenance. Batteries need to be checked and replaced over time, and the system components must be kept clean and in good repair to ensure efficient operation.

How Much Energy Does a Solar-Powered Electric Fence Use?

The energy consumption of a solar-powered electric fence can vary widely based on several factors, such as the length of the fence, the type of animal being contained or deterred, and the amount of vegetation touching the fence. Typically, most electric fences will consume 2 to 25 watts, but large fences can consume over 100 watts. How much electricity your specific fence consumes will vary. 

Let’s say your fence requires around 10 kWh per month. That’s relatively low when you consider that the average American household consumes about 889 kWh monthly. However, for larger farms or areas with higher containment needs, the energy usage can be significantly higher.

What Size Solar Generator Do I Need to Power an Electric Fence?

When selecting a solar generator to power an electric fence, it’s crucial to consider your specific energy needs. The generator must match the power consumption of the fence and accommodate operational duration, considering daily sunlight availability and battery storage capacity.

For example, if your fence consumes 5 watts per hour, you’d need a system capable of sustaining this load. Let’s use the following equation to calculate daily usage: 

Watts x Hours / 1000 = kWh

5 watts x 24 hours / 1000 = 0.12

This means you’ll use .12 kWh per day, assuming you power your fence around the clock. Multiply that by 30 to get 3.6kWh per month of use.

In this case, when choosing your solar generator, keep in mind that you need it to produce .12kWh per day and have sufficient storage to keep your electric fence operational when the sun isn’t shining.

Different solar generators will generate different amounts of electricity. The number of hours of peak sunlight you receive per day and the solar panel’s rated power give you an estimate of how much electricity it will produce. The capacity of your solar battery indicates how much electricity you can store. 

To determine the size of the solar generator you need, determine how much electricity your electric fence consumes. Then, ensure your generator can produce enough electricity daily to maintain that and that your battery has enough storage capacity to keep the system powered when the sun isn’t shining.

An option like the EcoFlow DELTA Pro + 400W Solar Panel suits larger setups. It’s part of an expansive ecosystem that includes the Whole Home Generator bundle, providing comprehensive energy solutions with considerable storage and solar charging capabilities.

When planning for an electric fence, a balanced approach between daily energy production and storage capacity ensures efficiency. With the right size generator, like those offered by EcoFlow, you can maintain your electric fence’s operation with reliability and peace of mind.
