How Does a Solar Powered Generator Work?

Solar-powered generators are completely different from their predecessors such as gas generators. Their structure is different, their working principles are different, and in short, they are completely different from gas generators.

The main difference between a Solar generator and VS Gas Generator is their fuel. The earlier relies on pure green energy of solar power and the latter on fossil fuel which is a direct contributor to pollution of the environment. Therefore, we can see a major shift in the power as well as car industries heading towards solar power to cut emissions.

Here are the main working principles of a solar generator and solar power station.

How to charge a solar power station?

Most solar power stations can be charged with 3 common methods. Whereas, the gas generator can only operate via gas used as fuel. On the other hand, solar-powered generators can be charged via 4 options such as:

  1. Solar Panels
  2. Wall outlet AC
  3. 12V/24V car socket cigarette lighter

Other than the above-mentioned methods, several solar power stations provide the options of charging with dual wall outlet AC and with lead acid battery.

Fast recharging capability:

There are cheap and expensive solar generators that use different charging methods which also enhance or decrease their charging capability. A good solar power station is expected to use X-Stream, QUALCOMM Quick Charge 5, and MPPT charging technologies to significantly reduce the charging time.

All those charging technologies are fast, reliable, and time efficient. The most reliable and widely used technology that we noticed in our top 17 best 1000W solar generators was MPPT charging. MPPT not only doubles that charging current but also helps in better power supply to devices.

Working phenomena of a solar power station:

The working phenomena of a solar power station are simpler as compared to a gas generator.

  1. Batteries

A solar generator consists of batteries that get charged using advanced technology such as MPPT and Battery Management System (BMS) which helps them charge quickly within a few hours and discharge slowly. Whereas gas generators mainly consume gallons of fossil fuel, there a smart solar power station has efficient Lithium Iron Phosphate (LiFePO4) battery. With LiFePO4 the charge stays longer when on standby and discharges slowly as compared to traditional lead acid batteries.

In addition to this, LiFePO4 batteries ensure 100% cycles of a battery with enhanced protection, consumption, charging, and discharging. It’s a major difference in how a solar generator differs from a gas generator.

2. Use of advanced technology

A good solar generator uses MPPT pure sine wave technology that charges the batteries quicker and provides a stable current power as compared to the PWM-based power stations. It is always recommended to buy an MPPT-based solar generator to get better performance in the short and long term. You can check out the 10 best solar generators that are based on MPPT by clicking here.

3. Protection and Reliability

The world has advanced and quickly moving towards the adoption of more green energy and reducing carbon footprints. A simple gas generator is based on a dynamo and piston engine to produce and convert energy. The story is opposite on the side of a solar generator.

A solar generator uses multiple advanced technologies to protect all your devices and ensure safety. To name a few:

  1. Over Temperature Protection
  2. Short Circuit Protection
  3. Over Charge Protection
  4. Over Power Protection
  5. Over-Discharge Protection
  6. Over Voltage Protection

These are the few protections installed in a single piece of silicon chip processor to protect all your devices. If you want to buy a solar generator that included all these protections, please visit our best 500W solar generators page to pick up the best one.

A solar generator is a necessary component for not only camping but it can also be kept at home to counter blackouts and sudden electricity breaks down. Screen indicators are a standard feature of modern solar generators that help monitor power consumption and charging even via a mobile app. On the other hand, a gas generator is deprived of such features as standard. Indicators on the screen allow you to monitor live power consumption their amperes, charging speed, input watts, output watts, and the number of ports in use.

Do solar generators work at night?

Solar generators unlike traditional gas generators have battery backup. The backup may range from 100W to 5000W depending on the configuration of the power stations. Greater the Watt power greater the battery backup time at night. The solar generator gets charged in the daytime and stores current in its batteries for nighttime usage. The latest solar power stations consist of LiFeP04 batteries that provide longer backup than the traditional acid lead batteries even when they are on standby.

Mobile Power APP for Monitoring

However, we recommend that only operate after ensuring that the solar generators you have purchased have all the above-mentioned features. It can be seen in the manual book provided by the seller.

Is solar generator worth it?

Solar generators are comparatively a newly introduced product with almost a 5-year history. Therefore, buyers get worried before buying one. However, our work with solar generators, research, and customer reviews have drawn a line between solar generators vs traditional gas generators where the earlier stood as a winner. There are several valid reasons behind this:

  1. Solar Generators VS Gas Generators

A Solar generator does not have only environmental benefits, it also mitigates gas expenses to a significant level. There are the best solar generators installed in houses, RVs, vans, and people charging their devices at camping. Today solar generators have become the new normal and gradually reducing the place of gas generators in the market. This shift has clear reasons as gas generators require over-haul maintenance which is not only costly but also tiresome as well as unreliable. A single thing goes wrong while refueling or changing the oil and it can ruin your camping experience.

  1. Solar Generators VS Battery Bank

Here are other reasons that solar generators are completely worth it. A battery bank does not have any additional source such as an AC wall outlet while you are camping to get charged. Here come the solar generators that can be charged to their maximum peak from dawn to dusk. The advance system of Battery Management System and MPPT ensures that all your devices are not out of power all night long. Read a complete and thoughtful comparison between a solar generator and VS battery bank for a better understanding.

Battery banks do not have LiFePO4 batteries that support quick charging, long standby mode, and slow discharge of current. On the other hand, advanced and the best solar generators do have LiFePO4 batteries combined with Pure Sine Wave flow making it possible to use the battery juice with maximum efficiency.

Do solar generators work on cloudy days?

Solar generators do work on cloudy days. However, their efficiency decreases significantly from 100% to 40% on dark cloudy days. Fortunately, we do have advanced solar panels with mono-perk technology that can improve the performance of solar panels from 20% to 30%. Reflective solar panels’ dual light capturing from both sides of the panel can perform better on cloudy days.

How long will the solar generator run?

Solar generators have the potential to keep on running the whole day from dawn to dusk. Powerful LiFePO4 batteries with Battery Management System ensure smooth running of 8 to 10 hours all night long. Solar generators with LiFePO4 charging efficient technology can retain the charge for a longer period when on stand-by mode as compared to traditional acid lead batteries.

How to use the solar generator?

Solar generators are simple to operate, easy to use, and convenient for traveling. They can be charged with portable solar panels on the go which ensures all-day-long free-green solar power. At night LiFePO4 batteries with efficient MPPT Pure Sine Wave keep all devices powered up all night long. Solar generators are charged using 4 methods. Here is our guide (Jump-Section) to find out how a solar generator work and to extract the maximum out of your solar generator.

Where is the solar generator to be placed?

If the solar generator has been installed at a house and is being used as a UPS, then it is safe to place it in an isolated and cool place. Solar generators are made and designed by psychological experts to ensure maximum portability. Its compact design, lightweight, and comprehensive but useful onboard features allow it to be traveled along and used conveniently on the go.

How much can a solar generator power?

There is available a wide range of solar generators on the market. A solar generator can range from 100W to 12KWh/3600W. All the generators in this range are portable solar generators.
