7 Best Solar Generators for Off-Grid Living in 2024 Reviewed

With an ageing power network and increasingly unpredictable weather events, coping with life off-grid is becoming a matter of necessity rather than choice. Add to that the skyrocketing costs of fossil fuels, and you’ve got the circumstances for a perfect storm. 

Sourcing the right solar generator can keep your life working in a power outage and provide a more affordable way to power your home.

Solar generators supply vital energy for camping trips, backup for medical devices, and even home appliances in remote areas for truly off-grid living.

But not all solar generators are suitable for all circumstances. The power needs of a solo camper going off-grid in the woods for a week will be different from a family of four that needs a reliable emergency power supply. 

Here are the seven best solar generators for off-grid living, whatever your reason is for doing it.

How to Choose the Best Solar Generator for Off-Grid Living

In 2020, the average person experienced eight hours of power disruptions. It may not seem consequential until you consider that number will only go up given the country’s ageing infrastructure and other disruptive events like natural disasters. The grid can’t supply a reliable, unfailing source of power. A solar generator can help when off-grid living becomes more than a novelty but a necessity. 

Here’s how to choose the right one. 

Appliance Energy Use

Capacity is crucial in making the right choice of generator. If your solar generator is just for power outages and your household needs are modest, then a small unit will do. 

If you want to keep a large family home functioning in a severe weather event that could last several days, you will require a much more powerful solar generator.

Check out how many watts will be required to power your appliances, as they vary. Look at the capacity of each generator for the appliances you want to support and the run time. Some appliances like fridges or air conditioning systems are much heavier on power than others.


Ease of charge and speed of charge are two essential considerations. 

Emergencies call for a rapid recharge time. Some solar generators are impressive, often recharging in just over one hour, but this is from a wall outlet that is no good during a power outage or camping trip.

A slower charge from a couple of solar panels might suit your needs if you are on an outdoor vacation or taking a van trip. If your generator is designed for the great outdoors, check whether it will charge with a 12V car adaptor.

Ease of Assembly and Usage

Most off-grid solar generator systems require additional accessories to get everything up and running to your satisfaction. At Ecoflow, we’ve always made ease of assembly and usage a priority — but now we’ve made it even easier! 

If you’re the kind of person who wants a solution that works right out of the box and doesn’t want to fully customise your off-grid solar system, check out our new Power Kits! They make off-grid living a breeze — at a highly competitive bundled price.


Planning to take a van trip, go camping or enjoy an off-grid holiday? Portability is a crucial dRiver in your purchasing decision, plus the ability to add extra capacity if needed.

Many people only think about portability when it comes to van trips or camping. However, portability can be critical in the home if you want to move the generator around the property during different times of the day and night.

You might want to power kitchen appliances during the day and then move the generator upstairs to support a medical device overnight. More powerful units will be heavier and not always suitable for some people to lift easily.

A portable and compact unit is also easier to store discreetly when not in use.

Additional Power

You can boost some solar generators with an additional battery pack which can double the system’s power but is detachable to ensure that the unit remains lightweight and portable.

Adding an extra battery is also a cost-effective way to boost power while retaining flexibility.

UPS stands for Uninterrupted Power Supply. This feature is crucial if you are using a solar generator for backup for a medical device. Some units do not offer UPS. Even though the drop may be just milliseconds, this can be enough to upset a sensitive appliance or disrupt medical equipment.


When it comes to solar generators, the old mantra of ‘you get what you pay for’ certainly does ring true. However, there is no point in spending money on unnecessary output if you don’t need it.

Generally, the higher the wattage, the higher the price. However, some exceptional budget-friendly solar generators on the market still offer plenty of power and durability for a competitive price tag.


Solar generators are a popular choice compared to fossil-fuel-driven equivalents as they offer a quiet, fume-free green alternative both inside the home and at off-grid outdoor locations.Solar generators offer flexible and sustainable power choices if you want seamless power during an outage or are heading into the great outdoors on a wild adventure.
