If you are looking for a power backup in power outages, this might not be ideal for those purposes. However, it will be a good way to power your small devices when outdoor. For that price, it is a device worth looking in to.
A solar generator is a system that gathers sunlight through solar panels. This energy is in the form of direct current (DC). An inverter is then used to convert this power into alternating current (AC). It is then deposited into a battery bank and used through a standard plug-in outlet.
Solar generators are classified into two categories.
These generators are generally used as a power back up in homes in case of power outage. They are stationary and will typically sit outside the house ready to automatically go on when power is out.
Home generators have quite a high wattage capacity, and will usually feature more than one battery to increase power storage.
Portable solar generators as the name suggest allows moving and having the power of renewable electricity from one place to another. These generators are often lighter than home generators and are also easy to pack and store. They are useful for outdoor activities, camping, or even as smaller backup power sources.
Unlike home generators, portable solar generators have lower wattage capacity but are still able to power and recharge small items.
Each generator comes with various key elements that could greatly affect their effectiveness. We shall look at these elements for a better understanding of their importance and how they affect the overall performance.
Battery storage capacity is the first thing you want to put into consideration when choosing a solar generator. Battery storage provides power at night or when your energy needs are more than the solar input.
Knowing a solar generator’s usable watts (not total battery rating) helps determine how long specific applications can be run. It is recommended to look for 1000+ of usable watts-hours to have great usability and reliability. It is also advised to use only 70% of the full capacity of traditional lead-acid batteries for longevity and preservation.
That said, however, not all solar generators come with built-in batteries. If that is the case, you will need to buy separate batteries for your power storage.
A portable solar generator or one with separate PV panels will allow solar tracking. This is the ability to move your panels according to the sun’s arc to capture the best solar input continually.
Solar PV input is interconnected with the storage capacity of a solar generator. Meaning, if the solar generator is in use while recharging, the time taken to reach its full capacity will also increase.
Inverters perform the task of converting DC power from the panels into AC power for standard plug-in appliances. They also rate the actual wattage you can pull from the generator at any one time.
Lower inverter rating means you are not able to power devices and appliances that require higher wattage.
However, be watchful for big inverters but with little battery storage and those without inverter external charging capabilities. However, generators with inverter chargers can acquire battery power from other sources besides solar panels.
Having a solar generator either for off-grid usage or as an emergency backup means that it has to be reliable. In this case, it is important to know the component warranties and their projected life spans.
The quality of these components will in turn directly affect the durability of the generator.
It is also very important to look for a durable generator casing such as one made from metal. These will withstand stringent use as opposed to plastic that will quickly wear off in rugged situations or from sun exposure.
The wattage of a solar generator could range from as low as 4 watts to as high as 1,500 watts. A point to note is, the lower the wattage of a generator, the longer it will take to charge. Don’t purchase a low watt generator just because it is cheaper. The cost shouldn’t compromise on quality and the delivery of the power that you need.
The amount of time it takes for a generator to charge is something that shouldn’t be overlooked. Therefore, it would be good to compare the generators’ charging times when plugged into an outlet and when placed under direct sunlight.
Balanced system design is yet another important factor to consider. This refers to how well the key and components fit in together to give ratings that support end usability.
In other words, a balanced system design is pared by proper usable storage capacity, solid PV input, and appropriate inverter rating.
Integrating high-quality components and balancing the system design will give a reliable solar generator that works with various applications.
A solar generator’s weight, size, and shape will be dependent on where you intend to use it. For outdoor activities, a unit that is compact but not heavy might be idea
When it comes to the shape, solar generators come in various shapes. Some can be easily folded and stored while others come in heavier models and on wheels for easier transportation.
When searching for a solar generator, consider how and where the power is stored. You might need to purchase separate accessories such as USB plugs or wall sockets. Some generators might just need the basic alligator clips and an external battery.
We all love the idea of free electricity from the sun. Owning a generator that isn’t releasing dangerous emissions like gas generators will be a welcomed idea any day. As we have seen in the best solar generator review above, there are plenty of great generators to choose from.
In our reviewed list, however, our best pick has to be The Goal Zero Yeti 400 Solar Generator Kit. it is extremely quiet to operate in comparison to traditional gas-powered generators. We love that the Yeti 400 is very portable and the panels fold up nicely, protected inside a canvas sleeve.
Another impressive feature of this generator is the use of Lithium battery technology that triumphs over older battery backup systems. While it may seem pricey, the Yeti 400 is highly versatile and durable to last many years.
With this in-depth review, we hope you can now make an informed decision as you embark on your solar generator hunt. Please share your thoughts and experiences with us in the comments section.
