How to Buy the Best Solar Generator: A Comprehensive Guide

Solar generators can be a fantastic investment for anyone who wants to have emergency backup power or to enjoy outdoor activities without relying on electricity from the grid. However, choosing the right solar generator can be tricky, especially if you’re not familiar with the different features and specifications. To help you make an informed decision, here are eight things to consider when buying the best solar generator.

8 Things to Consider When Buying the Best Solar Generator

Power output

The power output is one of the most crucial aspects to consider when buying a solar generator. You have to choose a generator that can provide enough power to meet your energy needs. If you intend to use it for powering your home, you’ll need a generator with a higher power output than one you would use for camping or outdoor activities. Look for the total wattage or output of the generator to be sure that it can satisfy your energy requirements.

Battery capacity and charging time

The battery capacity determines how much power you can store and use without relying on the sun. A higher capacity battery means you can use more appliances and devices, and it can last longer even without sunlight. The charging time is also important since it determines how long you’ll have to wait for the generator to be ready to use. Look for a solar generator with a fast charging time and an adequate battery capacity to meet your energy needs.

Weight and portability

If you’re planning to use your solar generator for camping or outdoor adventures, portability is a crucial feature to consider. Look for a generator that is lightweight and compact to carry easily. You can choose a foldable or modular design that can be disassembled for easy storage. Conversely, you may want to consider a larger generator with wheels and a handle if you plan to use it primarily for home backup power.

Durability and weather resistance

Solar generators can be expensive, and you need to choose one that can last for a long time. Choose a generator that is made of high-quality materials, and that can withstand harsh weather conditions. Make sure that it is waterproof and can resist rust and corrosion to ensure that it can survive rain, snow, and other outdoor elements.

Inverter type

The inverter is responsible for converting the DC power generated by the solar panels to AC power that you can use to power your devices and appliances. Look for a generator with a pure sine wave inverter that will provide a high-quality, clean output, free from any power surges. Modified sine wave inverters are cheaper but produce a lower-quality AC output, which can be harmful to sensitive electronics.


Another important factor to consider when buying a solar generator is its expandability. You might want to add more solar panels or batteries to your generator in the future, and therefore, you need to ensure that the generator you choose can be easily expanded. Look for one that features modular designs where extra panels and batteries can be attached.

Noise level

Solar generators can be much quieter than gas-powered generators, but they still produce some noise during operation. Look for a model that produces the lowest possible decibel level, especially if you plan to use it in residential areas or camping sites. Additionally, look for models with silent modes that switch off any fans or alarms to make it quieter.


Finally, you want to consider the features that the solar generator offers. These can include an LED light, USB ports, AC outlets, DC outlets, and safety features such as overload protection. Look for the features that are most important to you and ensure that the generator you choose meets those needs.


In conclusion, choosing the best solar generator can be easy if you know what features to look for. Consider the power output, battery capacity and charging time, weight and portability, durability and weather resistance, inverter type, expandability, noise level, and features when shopping for a solar generator. By considering all these factors, you can choose a solar generator that suits your energy needs, budget, and lifestyle.
