Best 3000 Watt Solar Generator Buying Guide

In order to make an informed choice on what generator to purchase it's important to understand how they work and what to look for.

We won't bore you with too much about the technology behind solar generators but generally, they are user-friendly and simple machines. Simply put, a solar generator converts energy from the sun to provide power to any devices that need electricity. 

Most of the time solar generators use the sun as their source and many people choose solar panels as a lifestyle choice to embrace environmentally friendly living. However, it's useful to bear in mind that a solar generator doesn't always need solar input to generate energy. 

Some solar generators can be plugged into an outlet on the wall, such as an ac wall charger or a charging port in the car to charge up their batteries. 

When the battery system is charged, electric devices can then be powered by the solar generator. Although models vary, most solar generators are able to charge multiple electronics that would usually need a normal AC plug, a DC plug, or a USB port.

When you hear the term 'shelf life' when referring to a solar generator this refers to the time it takes to fully charge the battery and how long it will remain charged and ready for use.

Solar Generator Components 

Batteries

The solar generator battery is one of the most important parts of your solar generator. Batteries come in various types such as lead-acid, lithium-ion etc and have capacities of 3000 Wh, 1000Wh etc.

The most common is a lithium battery which offers enough storage for most requirements of the solar generator. Some solar generators offer extra storage that can be added in a battery bank so if this is something you might need make sure your specific purchase offers this.

Charge Controllers 

It's easy to overcharge batteries and they can easily become damaged so to minimise the risk of this most solar generators come equipped with a solar charge controller to help regulate the input and output voltage from the panels.

This component is a vital addition and helps maximise the life, efficiency and quality of your solar generator.

When searching products look out for the most common types of controllers which are MPPT & PWM. MPPT charge controllers have proven to be the most efficient. 

Inputs and Outputs 

A solar generator gets its power through a charged battery. Solar generators will generally have a port that enables you to charge the battery using the solar panels and an additional port for charging the unit through a normal AC outlet.

Many solar generators also include an extra port for DC charging in a vehicle but often it needs to be purchased separately.

When your solar generator is ready for use you can plug electronics into the outputs on the exterior of the unit.  Most solar generators will have several AC, DC, and USB plugs to power whatever is needed.

Display

Most high-quality solar generators have a display, quite often an LED screen that uses information about what's happening in the system. 

Displays are important to help you understand the rate at which electricity is going through your solar generator as well as how much power you have left.

Size

If you opt for a portable generator you need to ensure the portable solar generator will provide your entire power needs. . There are ways to identify what generator will best suit you so let's have a look at a few.

Running Watts 

Running watts show the electricity the generator can provide on a continuous basis. 

Once you have this information you can tally the wattage required on your devices which are often detailed on the device itself. Then ensure the running wattage is greater than the total.

Watt Hours 

Watt-hours refers to the capacity of the generator. It shows how long it can power devices. It allows you to see how much consistent power the generator can provide for 60 minutes when the battery has a full charge.

It also helps you figure out how much power the generator can provide before it needs to be recharged.

A 600-Wh generator could power a 50-watt light for 12 hours or several 100-watt devices for three hours before the battery capacity is compromised.

It's important to bear in mind that there are lots of variables. For example, the temperature can affect the battery. And the capacity of the battery can be affected by multiple devices charging at the same time.

So be sure to multiply the total wattage of all devices you will need to charge by the time that's needed to run them. You’ll need to purchase a generator that offers an hour-watt capacity that is greater than the result.

Peak power

The peak power of a solar generator shows the power that a generator can provide just before it starts the running output. The measurement should be higher than the running watts.

This brief run of extra power is required to start the motors on devices such as mini-fridges or fans. So if you're planning on powering motorised devices figure out the starting wattage to ensure the peak power output is adequate.

Recharge Time

Recharge time is the length of time it takes to charge a fully flat solar generator to full charge.

You should read the documentation that comes with your purchase. This should give you an idea or estimate of the charge time needed and the speed of the specific generator you are purchasing.

It's useful to remember that the speed time has been based on getting maximum input of solar power which, given the nature of weather, may not always be at optimum levels.

If you think you will be relying on your solar generator to power lights, TV and mobile devices over the course of a few days then you must make sure the charge and capacity rate will give you enough power.

Although you are able to supply power whilst simultaneously charging it's best avoided as it will take longer to charge your devices and use power faster.

Frequently Asked Questions 

What inverter type do I need? 

If you are looking for an economical inverter then the sine inverter is a good option and works well with several devices. However, it's not the best option for all generators so it's important to research as much as possible beforehand.

Some modified sine inverters cause an annoying noise in the audio and can disrupt the functionality of other devices. If possible invest in a pure sine wave inverter, although more expensive, they are a better option especially for sensitive electrical equipment.

What battery type should I choose?

A solar generator uses a lithium battery, lithium-ion or lead-acid to store its energy. Solar generators that use lead batteries are generally less expensive than lithium-ion but will be less effective and not last as long.

Lithium-ion is the better option and they are much lighter meaning portable solar panel generators will be easier to transport.

So, there we have it a guide on buying a 3000-watt solar generator, let the search commence!
