Over the last several years great strides have been made in off-grid and portable power generation. Solar panel tech has advanced to the point where you can easily and affordably power your essential electronics when camping or in a survival situation. The real problem is taking the power from solar panels and making it usable. A solar powered generator is the solution. Today we’re covering the best solar powered generators to help you pick out the one that provides the best mix of features and quality for your needs.
What is a Solar Powered Generator?
Solar generators are interesting in that they don’t generate power on their own. They’re basically battery storage devices designed to process the sometimes inconsistent power from a solar panel and make it more useful.
They’re made up of three core devices:
- Charge Controller
The charge controller protects the battery from the changes in voltage and amperage produced by solar panels. It allows you to charge your battery up steadily and ensures the greatest longevity for the battery.
Once the power is stored in the battery the inverter changes it from DC power to AC power. This allows you to charge devices the same as you would from your home.

Buyer’s Guide to Buying the Best Portable Solar Generator
Solar powered generators are actually a little misnamed. They don’t actually generate power on their own, instead they take the power generated by solar panels and make it more usable.
Picking out the best solar generator comes down to a few key features, with capacity, charging capability, and battery type some of the most important.

We’re not going to sugarcoat it, solar powered generators are expensive. Entry priced models start around $200, with high capacity ones running as high as $2,000+.
There’s a clear connection between battery capacity and price. As the inverter and battery improves it becomes much more expensive.
The majority of solar generators offer multiple charging options. Solar panels are of course one of the options available, though you should check the type of panels they accept.
Some manufacturers have proprietary ports that only allow you to use their solar panels to charge their solar generators. Smaller solar generators often charge only using a USB type plug from solar panels less than 50 watts.
For larger solar generators the most important solar specific plug is the MC4 connector. This is rapidly becoming the standard for small scale and portable solar panels.
You can also charge your solar generator from a standard wall outlet or a car cigarette lighter port. Some generators come with an adaptor for this but you may have to purchase one separately.
Small solar generators usually have one to two ports for charging other devices. Most often this is a standard USB style port that allows you to charge most small devices.
As they go up in size and capacity more ports become available. Common ones include standard household 110 V AC, cigarette style DC, and some specialized DC ports for outdoor and survival equipment.
Really advanced solar powered generators even offer ports to connect with other batteries. This allows you to use the inverter and charge controller of the solar generator to charge up and use the capacity of the other batteries.
There are two battery types that power the vast majority of solar generators. These are absorbent glass mat (AGM) lead acid batteries and lithium batteries.
AGM batteries rely on a similar chemistry to the lead acid batteries in your car. They’re designed to be maintenance free and to function well over at least several hundred charge cycles.
AGM batteries aren’t as flexible as lithium batteries. They shouldn’t be drained below about 30-40% for maximum battery life and they’re heavier than lithium batteries.
Lithium batteries are basically larger versions of the batteries in your phone and other devices. They offer excellent energy density, can be drained fully, and provide close to a thousand charge cycles. The only real downside to lithium batteries is their price.
Lithium solar generators are consistently more expensive than AGM and similar batteries.
Charge time for solar generators is affected by the battery capacity and the type of charging. Solar charging generally takes the longest because of how inconsistent it can be. The sun only shines for so many hours a day after all.
Smaller generators can charge up in as few as 4 to 5 hours but larger ones can take over 24 hours. Wall outlet charging is consistently the fastest method available.
If you’re purchasing a solar powered generator for outdoor or emergency use we recommend you keep it plugged into the wall. This allows the charge controller to maintain the optimum charging pattern on the battery and makes sure it’s ready to go when you need it.
For those looking for a dedicated off-grid power source it’s important to monitor your incoming and outgoing power. You don’t want to draw the solar generator down to zero if you’re depending on the power.
Run Time – Storage Capacity
The capacity of a solar generator is determined by the size of its battery storage. This is measured in either watt hours or amp hours. Smaller generators may even be measured in milliamp hours.
There’s no one size fits all capacity for solar generators. Figure out what you want to power and how long you need to power it for. That will help you determine how much battery capacity you’ll need.
Generator with MPPT – Charge Controllers
One of the most important technical considerations when comparing solar generators is the type of charge controller. At this point you should only consider an MPPT charge controller.
That stands for Maximum Power Point Tracking and refers to the method of converting inconsistent solar power into stored power. It captures 93% to 97% of the power produced by the solar panels.
Older PWM charge controllers have much lower efficiency. They cut into the amount of power your solar generator can capture from solar panels.
Surge Power Capacity
Something to consider with any solar generator is the surge capacity it offers. Most generators have two different capacity numbers, their operating watts and surge watts.
Many appliances and devices make an initial watt draw higher than what they need to operate. Surge capacity allows your solar generator to start up these devices.
It’s important to remember the difference between surge capacity and operating capacity. Most generators can maintain surge capacity for a very short length of time only. Check that any product you’re planning to power falls within the operating capacity of your solar generator.
Different solar generators are designed with different uses in mind. Some are just large enough to power a few small devices like your smartphone or laptop. They’re designed to act as larger than normal charging banks that can be powered by a solar panel.
The next level of solar powered generators are capable of powering small appliances like fans, microwaves, and small refrigerators. These have much greater storage capacity and higher surge capacities.
This size of generator is great for one to two day long camping trips where you want some of the comforts of home. They can also be used as an emergency backup in case of power outages or disasters.
The largest solar generators can be used to run substantial appliances like full size refrigerators, freezers, or multiple smaller appliances. These are very large, quite heavy, and offer substantial surge and operating capacity as well as storage.
These are great for fully off-grid cabins and longer duration trips where you need to power equipment. They’re frequently used by activists in developing nations and for disaster preparedness.
Portability – Size and Weight
Solar generators range in size from hand held all the way up to wheeled carts. Entry level ones are designed to work with small solar panels and provide enough power to charge your phone or other small electronic.
These weight just a few pounds and often only have one or two charging ports. From there they rapidly increase in size and weight.
General purpose solar generators have sturdy handles to hold them by and usually weigh at least 15 to 20 lbs. They can be difficult for kids or smaller adults to move around. They’re definitely not something you want to cart in on a backcountry camping trip.
The largest solar powered generators can weigh over 100 lbs and are almost always mounted to some kind of cart. They often have telescoping handles that allow you to roll them like a rolling suitcase.
The smallest solar generators will have an indicator that shows battery level but not much else. As you move up the capacity ladder more detailed displays start to become standard.
Medium to large generators can show you breakdowns of power levels, input/output information, and battery voltage. Some even offer the ability to turn on and off different output sections as needed.
Picking out the best solar powered generator requires you to know how much power you need and what you’re willing to spend.
You have to balance out performance and capacity with your budget. As long as you know the basic power requirements you have a good starting point for picking out the perfect solar generator for your needs.
