Solar Generator Vs Inverter | Full Quick Comparison

Although there is a distinction between Solar Generator Vs Inverter, most people are unaware of them and think they are interchangeable. While inverters essentially convert DC to AC, generators produce electrical energy.

An inverter changes one electrical current into another, whereas a generator generates electricity. This is the key factor to consider when comparing generators and inverters. Electrical current comes in two forms: alternating (AC) and direct (DC).

Solar Generator Vs. Inverter 1

Inverters are used when equipment that runs on AC power must be operated in a vehicle or another location with only DC power. The two machines serve different purposes, even though certain inverter generators may perform both for increased energy efficiency.

When we contacted a representative from 2nd City Gas Plumbing and Heating, who specializes in boiler repair Redditch, he said that inverters operate differently from generators and have grown in popularity recently due to their ability to create silent AC electricity and lack of noise.

Inverters’ primary benefit is their incredibly high-quality, steady power output. Another rather evident drawback of inverters is their high price. On the other hand, generators must run continuously at a speed of roughly 3600 rpm to generate electricity. Although they are pricey, their biggest drawback is that they are incredibly noisy.

Generator vs Inverter


As its name suggests, a generator generates energy once it is turned on; it does not store electricity. Therefore, it must be initiated first for it to supply power. Once the utility supply fails, there will undoubtedly be a delay before receiving backup power. Direct current is the form of energy that a power inverter set stores in the batteries (DC).

Alternating current (AC) from the mains is first converted during charging and stored before being instantly converted back to AC to power your appliances. There is neither a timer nor a manual start.


An electricity generator produces it. It is a mechanical device that utilizes spinning components to transform the calorific value of diesel into electrical energy. An inverter solely stores and reconverts energy. An electrical signal with no variations converts DC power to AC electricity. It has the same qualities as the ideal alternating current when properly filtered.


Users must consider noise while weighing the pros and downsides of generators and inverters. Generators generate power by running their engines, which can be rather loud. The motor must run at 3600 revolutions per minute to produce power effectively.

It is challenging to quiet down the noise produced by this spin. Smart microprocessors used in inverters can significantly reduce internal noise. It assesses the connected output and modifies the amount of power generated, minimizing generator noise.


A DG set can be large and unwieldy, needing a metal frame and wheels unless your power backup requirement is minimal (just domestic lighting and home appliances). Although technically portable, they don’t offer the same level of convenience. An inverter itself is not a large, heavy object, but it can only function in conjunction with a group of connected batteries. These might be weighty and difficult to move about.

Operation: An inverter converts direct current into alternating current and vice versa using a combination of switches and rectifiers. It needs an electrical energy source to charge the batteries and turn them on as soon as the main supply is shut off. The output wave is smoothed out and given a stable current by passing it through a filter.

On the other hand, a generator transforms mechanical energy into electrical energy. Diesel, gasoline, or other combustible resources are used to power it. Burning the fuel causes a motor to rotate, creating alternating magnetic fields inside the generator, ultimately providing electricity. The output of the magnetic generator may change while it is running.


Diesel or gasoline is used by generators to generate energy. They need routine maintenance including oil changes, lubricant replacements, distilled water top-ups, and other tasks. They also make more noise. Maintenance is a good thing with inverters. They don’t need a lot of maintenance. Ensure the battery terminals are pure and adequate water is in the tank.

Cost: Despite making more noise and requiring more fuel to run, generators are less expensive to purchase than inverters. They are inexpensive to repair and simple to fix thanks to the accessibility of spare components.

Inverters cost more because of their smooth power flow, silent operation, small size, and other advantages. Even the most affordable inverters cost a little more than generators. However, the cost is reasonable.

Inverter Advantages

  • Electronic devices and other delicate equipment like PCs and personal printers are safer with an inverter. It generates a pure sine-wave output that is equivalent to the standard of the mains supply.
  • It offers continuous backup with no starting time or inconvenience—critical, for instance, for a doctor’s office.
  • generates hardly any noise.
  • Neither pollute nor harms the environment.
  • Greater operational efficiency results in lower operating costs.
  • The load has an inverse relationship with the backup time. The backup time increases as the load decreases.
  • The inverters of the future are made to work with solar energy. As a result, you can use solar energy to generate electricity, run devices, and even recharge batteries.

Inverter Cons

  • Batteries can be extremely pricey.
  • Battery replacement is highly expensive, especially if the inverter is only occasionally utilized (battery not cycled)
  • You’re left in the dark when batteries run out of electricity (voltage is too low to run an inverter).

Diesel-run Generator Advantages

  • Conventional generators are big and heavy for a reason. They can hold more fuel in them. A typical generator can be used for longer periods without running out of fuel if sufficient fuel is available.
  • The power output of an inverter and a generator differs significantly. Use a generator to generate 500 watts to 50,000 watts if you use larger equipment and require a lot of electricity. Therefore, a generator is preferable if your job requires a lot of electricity for an extended period.

Diesel-run Generator Disadvantages

  • Long-term higher maintenance costs as a result of the deterioration of moving parts
  • increased noise output
  • use of fossil fuels results in increased pollution
  • Lower efficiency and higher running costs as a result of rising diesel prices
  • fuel replenishment and storage inconvenience
  • Diesel storage poses a fire risk, necessitating installation far from the point of usage.
  • runs at the same 3600 RPM speed; thus, you may expect the same noise even if fewer appliances are connected. When load needs are lower, the price also increases.
  • Unable to work with solar panels.

Final Verdict

Despite being the two most widely used technologies in the power generation sector to lessen energy deregulation, Solar Generator Vs Inverter have different capacities and functions. Inverter generators, which employ the same technology described above, are very common these days.

Inverter generators create AC power first, convert it to DC, and then convert it back to AC power, which sets them apart from ordinary generators. This approach offers several benefits regarding power quality, fuel usage, noise output, and many other factors. Generators use mechanical energy from external sources, convert it into electrical energy, and then produce electrical power. They are complex, heavy-duty equipment with high capacities.

Frequently Asked Questions

What distinguishes a generator from an inverter generator?

Alternating current (AC) power is produced by conventional generators using a mechanical alternator. Inverter generators similarly use an alternator to generate AC power. Still, this electricity is first converted to direct current (or DC) before being inverted again into more dependable AC power by a microprocessor.

Which of the two, solar or generator, is better?

Appliances can be powered directly off of a generator without the need to charge the battery first. When used with power-hungry appliances like your air conditioner and coffee maker, they are superior to solar. Generators are not weather-dependent, which is probably their major advantage over solar power.

Is a solar generator nothing more than a battery and an inverter?

The four essential components of a solar generator are the inverter, solar panels, battery, and charge controller. Solar generators are essentially portable solar installations because of these four elements. Using a solar generator, you may efficiently house the essential elements in one practical system.

Is purchasing a solar generator worthwhile?

Compared to gasoline-powered generators, solar generators have no additional running costs after the initial cost of the equipment. They provide an infinite supply of energy produced by sunshine, so no gasoline is required. They also don’t have moving parts, so less maintenance is required.
