What Is a Solar Inverter?

After solar panels create DC electricity, it must be transformed into alternating current (AC) before it can be used in your home. This is the job of a solar inverter.

The inverter takes the variable direct current output from your solar panel array and changes it to 120V/240V alternate current power for your household appliances. Smart inverters do many other tasks as well, including monitoring your system.

Reliable Power Generation

During the day, your solar panel array produces DC power from the sun that SOLAR INVERTER is sent to your inverter. Your inverter then converts that DC power into usable AC electricity for your household. It also monitors and reports data on the performance of your system. This information allows your installer to identify issues or faults and respond accordingly.

While some people install a single inverter that transforms all of the solar panels’ DC power into usable AC energy, more reliable solar systems use microinverters. These small inverters are attached to each solar panel and independently convert the DC power from each solar panel into AC power for your home. This prevents shading and orientation issues from impacting your power production. It also offers panel-level monitoring and makes it easier to expand your solar system in the future.

The failure rate of grid-connected PV inverters is four times higher than any other component. The main cause of this is the increase in operating temperature, which reduces the lifespan of key components such as metal-oxide-semiconductor field-effect transistor (MOSFET), insulated gate bipolar transistor (IGBT) and bus capacitors. The existing reliability evaluation models fail to consider the thermal characteristics of these components, which reduces their accuracy.

Some inverters can also work with home storage solutions like batteries to provide backup power during grid outages or at night. They can even communicate with the utility grid, synchronizing their frequency and voltage to meet the standards set by the grid.

Reduced Energy Bills

Solar energy reduces a home’s electricity bills by offsetting expensive utility prices and by generating clean power that is free of pollution. The reduced costs, coupled with governmental incentive programs, make going solar a sensible and sustainable investment for homeowners.

A solar inverter converts direct current (DC) from solar panels to alternating current (AC). This allows the power to flow both ways, so your lights and appliances can receive it. It also gives the power grid a steady, high-quality output that won’t damage electrical equipment.

Inverters accomplish this DC-to-AC conversion by switching the direction of electricity back and forth extremely quickly. The result is a fluctuating voltage that creates a sine wave, which can be injected into the grid without damaging its electronics.

The two main types of solar inverters are string inverters and microinverters. String inverters are larger devices that accept DC input from many solar panels and transform it all into AC. They work well in applications with no shading or complex roof lines, where keeping installation costs low is important.

Microinverters are small electronic devices installed on each individual solar panel to maximize their performance and power yield. They are recommended when shading or complicated roof lines exist, where a more cost-effective solution is required. Alternatively, they can be used in conjunction with a battery storage unit to enable customers to participate in utility-backed demand response programs.

Increased Home Value

Many homeowners choose solar because they want to reduce their reliance on fossil fuels, but it’s also a great way to increase the resale value of their home. Multiple studies have shown that homes with solar panels sell for more than comparable homes without a system. A large-scale study by Berkeley Lab found that homebuyers are willing to pay a premium of about $4 per watt for a home with solar. This equates to about $15,000 for a typical solar energy system.

Solar is especially valuable in areas where electricity rates are high, as buyers will see significant savings on their monthly bills over time. This added value also helps to offset the upfront cost of solar, making it an affordable and desirable investment for new homeowners.

The type of inverter you install will also play a role in the overall cost and performance of your solar system. For example, a hybrid inverter allows you to connect batteries to your solar system, providing additional flexibility for power generation and storage. Hybrid inverters are also more efficient than non-hybrid inverters, which are limited to using DC coupling between the solar panels and battery.

Peace of Mind

Peace of mind is a state of being that’s closely linked to your mental health and general well-being. When you feel calm and clear-headed, it’s easier to be more purposeful in your life and find fulfillment.

Many people struggle to achieve peace of mind, especially when they are weighed down by stress or anxiety. One way to get there is by learning healthy coping mechanisms for dealing with challenges that come your way, like meditation or other mindfulness-based practices. But it’s also important to look within yourself for the source of your stress. The phrase peace of mind has been used in written form as early as the 1600s and is an evolution of earlier constructions such as peace of conscience and peace of soul.

A solar inverter is a component that’s subjected to significant strain for long periods of time, so it’s important to buy quality products that will stand the test of time. That’s why it’s important to choose a company with a reputation for reliability, like Sungrow, which is backed by the Top Brand PV seal in Germany and Australia and is a TUV Rheinland All Quality Matters award winner. They offer a wide range of inverters including the 5 to 10kW Goodwe MS series with up to four independent MPPTs and the 3 to 5kW Goodwe X-hybrid inverter that’s battery ready.
