Maximizing Solar Energy Efficiency with the Right Inverter

When it comes to solar energy, solar inverter system efficiency is a key factor in determining system longevity and performance. An important component of this efficiency is the control of electrical current. Demand for solar inverters has surged in the last few years in Botswana. This is a result of people realizing the benefits of converting to solar energy for residential and commercial use. Even better, those who install solar power systems on their houses and businesses can receive cash incentives from them. Apex Mart is trusted name for buying Solar Inverters in Botswana.

Importance of inverters in the conversion of solar power

  • The inverter's performance determines a solar panel system's efficiency since inverters change Direct Current (DC), generated by the solar panels, into Alternating Current (AC), utilized by the electrical grid.
  • Many are left wondering how the total efficiency of the system will be affected by the over-sizing or under-sizing of an inverter.
  • The inverter of a solar system operates best within a set operating "window," typically specified in the inverter's specs.
  • The inverter's capacity to effectively convert DC electricity to AC electricity varies with the power input from the system's solar panels.
  • The inverter is said to perform at its best if the input from the panels is contained within the window's viewing area.

Difference between Standard Inverters and Solar Inverters 

Solar Inverters are an essential component of the solar energy production system, which are synchronized with batteries, charge controllers, blocking diodes, switching circuits, and solar panels. It takes the DC electricity produced by the solar panels, transforms it into AC power, and synchronizes it with the remaining solar power system. This system may or may not be connected to the grid, and it may even be connected to a backup battery bank. Batteries are not necessary for solar inverters to operate.

Normal inverters employ switching, transformers, and control circuits to convert DC to AC, just like solar inverters do. A typical inverter and inverter battery are connected to the property's main power connection; conventional inverters rely on energy from the grid. A conventional inverter requires grid power to charge its battery, and without a battery, it cannot function.

Types of Solar Inverter

There are five varieties of solar inverters, and each has benefits of its own:

Inverters with batteries

A battery inverter is the best option if you need to retrofit a battery into your solar system or if you want to keep your battery isolated from your solar panels and powered by a different inverter. Whenever possible, instead of using grid power, a battery inverter transforms the power from your batteries into 230V AC to feed into your switchboard.

Center-Based Inverters

Large devices like central inverters are utilized in systems that need hundreds of kilowatts or even megawatts of power. These aren't meant for household usage; they resemble enormous metal cabinets and can each manage 500kW of power. They are usually used for utility-scale solar farms or large-scale installations in the commercial sector.

Hybrid Inverters

Hybrid inverters sometimes referred to as multi-mode inverters, are rather unusual in Australia and let you add batteries to your solar system. Through a process known as "DC coupling," which uses an inverter to power both the solar panels and the batteries while using a DC charger to charge the batteries, it is connected to the attached batteries. The microelectronics in it regulate the charging and discharging of the battery.


As its name suggests, micro-inverters are incredibly tiny (roughly the size of a book)! The micro-inverter to solar panel ratio is one-to-one. The benefit of a micro-inverter is that it maximizes the output of each solar panel independently, producing more energy (particularly in shaded situations).

Strings Inverters

Last but certainly not least are string inverters. A single-string inverter is normally included in every solar installation, as these are the most popular inverters for residential use. Because they are attached to a series of solar panels, they are known as string inverters.

Efficiency of Solar Inverter

Higher-quality solar power inverters are more efficient, converting more electricity with fewer losses throughout the exchange process. Energy damage is negligible because most maximum high-quality inverters are between 97 and 99 percent efficient, though growth performance varies by brand. Your photovoltaic inverter can help you minimize the losses caused by shading and other factors that can lower your energy system's efficiency.

Important Considerations When Buying Solar Inverters

Capacity - The maximum load that the inverter can handle. For example, if the inverter's capacity is 1MW, it can accommodate a maximum load of 1MW.

Battery - When there is a power outage, the battery determines how much a solar inverter can unload and what loads can be supported.

Considerations for Surge Power - Surge Power is the greatest power that the inverter can deliver, usually for a short period. It is utilized for some appliances that require high power but then run on standard power.

MPPT (Maximum Power Point Tracking) - This technique is utilized by grid-tied inverters to optimize solar panels for maximum power output. Maximum power point technology refers to the best conditions in which Solar Panels produce the maximum power. It varies, however, depending on temperature, shading, irradiance levels, and other things.

Programmable Controls for Regulation and Monitoring - The output of a solar panel is determined by several elements, including temperature, irradiance, heat, shade, and others. To track the amount of energy produced by the solar panels, programmable controllers in the shape of display panels should also be installed.
