What is Off Grid
An off-grid solar system relies on energy from the sun to run homes, off-grid builds, or even recreational vehicles. Unlike grid-tied solar systems, batteries store any solar energy collected from panels in order to run some of, or your entire home. Off-grid solar system setups give you the freedom to live comfortably, and the option to run almost any appliance, rain or shine, morning or night.
How Does Off Grid
Solar System Work?
Solar panels capture solar energy using high-converting solar cells.
The charge controller regulates batteries to prevent overcharging and damage.
Energy is stored in solar batteries until it is needed.
An inverter ‘transforms’ DC current into usable AC output to power almost any appliance.

What’s in Off Grid
All off-grid solar systems include 4 major components: solar panels, a charge controller, a battery, and an inverter.
Solar panels come in all sizes and watts for portability or permanent mounting. Find the best panel for a home, off-grid living, or even camping.
MPPT charge controllers monitor solar panels, selecting the optimal voltage for the current scenario, or maximum power point tracking (MPPT). Charge controllers maximize system efficiency by optimizing operating voltages between the panels and batteries.
Without an inverter, solar energy is pretty useless. It turns DC current from solar energy or a battery into the more accessible 120/240v to run all your AC appliances.
Solar batteries store power collected from your solar panels. Often described as deep cycle batteries as they’re designed to charge and recharge or ‘cycle’ many times.
Connect solar panels to a portable power station to collect clean, renewable energy anywhere you go. With panels ranging from 110W-400W and power station capacities of up to 3.6kWh, solar generators are a portable alternative to off-grid solar systems offering a temporary solution for home backup, lowering your bills, or even for your off-grid adventures.

Benefits of Off Grid
The main benefit of off-grid solar systems is having complete energy independence for cabins and RVs. Plus, there’s also an opportunity to substantially reduce your carbon footprint.
An off-grid solar system can ensure your cabin has power that’s completely independent of the grid. In remote locations, solar energy is a reliable way to stay powered no matter what.
Freedom to Boondock
With an off-grid system like Power Kits, you’re free to travel and camp pretty much anywhere. You no longer have to rely on campsites for power and can top-up using solar from anywhere!
Lower Carbon Emissions
Burning fossil fuels releases carbon dioxide into the atmosphere, damaging the environment. Powering our homes, no matter how small, with renewable energies, such as solar, reduces the continuing damage caused by global warming, improving our environment for the future.

What Is the Difference Between Off-Grid and On-Grid Solar Systems?
An off-grid system is not connected to the utility grid. An on-grid — or tied — system is. With an on-grid system, your solar system diverts any excess power you generate to the utility grid. You may receive energy credits for this excess energy through a net metering program, but you don’t get to store off-grid energy in reserve. An off-grid system lets you use the energy you have generated, with any excess stored in your solar generator or portable power station.
How Do You Build an Off-Grid Solar System?
By assembling all the required components! You will need a power station/generator, PV solar panels, and a way to balance the system. EcoFlow provides a wide range of solar generators, portable, rigid, and flexible solar panels, and Power Kits. You can even build a customized smart home ecosystem to meet your energy independence needs. Whether you’re just starting with solar power or going for complete off-grid energy independence, EcoFlow can help.
How Many Solar Panels Do You Need to Run a House Off-Grid?
How many solar panels you will need depends on how much power you consume on average and the panels’ rated wattage. The average American household uses 886kWh per month, which amounts to around 30kWh per day. If you used a 400W solar panel and received 6 hours of direct sunlight per day, you’d generate approximately 2.4kWh per panel per day. You’d need around 13 PV panels to run a house off-grid.
How Much Does an Off-Grid Solar System Cost?
The cost can range from $4,500 to $50,000, depending on your equipment, required capacity, and labor costs. A solar system is more than panels—it requires a balance of systems, and every component adds to the price. Your energy consumption also matters, with the cost typically increasing in proportion to the capacity. Finally, any labor required for installation adds to the system cost. You can reduce costs by installing a Power Kits system, which has all the components needed for off-grid solar and allows for easy DIY installation.
How Many Batteries Do You Need for an Off-Grid Solar System?
Solar panels need to store the energy they create somewhere. Storage takes place in solar batteries or a portable power station. A single battery should suffice if you want a backup for personal devices and essential appliances when the grid goes down. However, if you want to go off-grid entirely, you could need as many as twelve solar batteries (or more, depending on capacity) to ensure you have enough power to keep you going. The right number ultimately depends on your energy consumption needs and the capacity of the batteries.
Which Is Better? An Off-Grid or an On-Grid Solar System?
Whether an on-grid or off-grid solar system is the best choice for you depends on your personal needs and where you live. Rural areas could benefit more from off-grid than on-grid, for instance, as their power supply tends to be less reliable or nonexistent. The biggest downfall of on-grid systems is that they can't protect you from grid power outages. But they are a handy way to offset electricity costs and provide electricity when your solar power generation falls short of your needs.
How Big Should My Off-Grid System Be?
As big as you need it to be. There is no one-size-fits-all approach. To answer this accurately, you need to calculate your total energy consumption by checking the wattage of all the devices and appliances you know you'll need, multiplying by the estimated run times, and adding the total for each item. The PV solar panels, power station, and Smart Extra Batteries that comprise your off-grid system should have enough power to meet your energy needs.
What Are the Advantages and Disadvantages of an Off-Grid Solar System?
The most significant advantage of an off-grid solar system is energy independence. You don't need to worry about relying on the aging electrical grid or vulnerable power lines. You have your very own electricity supply right at home! The downside is that you must stay on top of energy generation and storage. EcoFlow makes monitoring your usage and storage from anywhere easy with the EcoFlow smartphone app. Your solar system will need to be more expensive than an on-grid system to keep your household reliably powered.
Where's the Best Place to Install an Off-Grid Solar System?
The best place for your solar panels is where they will receive the most peak hours of sunlight, which tends to be facing south. You can set up the rest of the solar system, such as your solar generator or portable power station, as close as it needs to be to the solar panels. However, solar panels don't require direct sunlight to generate energy; options like bifacial solar panels can still provide electricity by making the most of ambient lighting.
