What to Consider When Choosing Solar Inverters

SMA solar inverters

In the modern day and age, solar power is increasing in use and application by the day. In this context, solar inverters play a hidden but significant role.

With the task of “inverting” the direct current (DC) generated through solar energy into alternating current (AC), which can be used to power up our homes and offices, these devices are crucial to the functioning of your solar system. It is crucial, therefore, that when it comes to selecting panels, that a system with a powerful inverter is chosen.

How is this done? Which factors need to be considered?

Our blog this week answers these questions, giving you all you need to know about picking the best solar inverter for your property.

Picking the right kind of inverter

On the market, users will generally find that there are three primary types of solar inverters.

These include:

Grid-tie inverters: Beyond converting DC to AC, these inverters come with the ability to synchronize with a utility line. This device is meant to transmit unused electricity into the grid and does not possess a battery.

Off-grid (stand-alone) inverters: Here, DC converts to AC from a storage battery. These inverters are typically used for residential and commercial projects, with low-watt models used to generate energy for the many appliances within a given property.

Hybrid inverter: What differentiates these inverters from the others is that they can be used in both grid-tie PV systems and off-grid PV systems.

Capability and efficiency

When it comes to picking solar inverters, choosing one that is highly energy-efficient is key. Gold standard inverters generally boast a conversion efficiency of over 98%, with the highest micro inverter efficiency recorded at around 96.5%.

It is important to note, however, that not every kind of high-efficiency inverter is suitable for your property. In certain solar inverters, the high current carried in cables that interconnect the modules and feed the output result in high cable loss due to electrical resistance. Thus, efficiency needs to always be considered in tandem with other factors such as this.

Therefore, before making a final decision, make sure you speak to an expert about these matters.

Supplier’s reputation

When it comes to picking solar inverters, it’s important that your service provider is reputed and recognizable.

In this regard, it’s important that you take steps to validate their experience and quality of work through a little research. This can be done by going through customer reviews of their service. Further, looking into whether they have a physical office as well as taking a peek into their social media channels can also provide an indication of what kind of customer experience you can expect.

This way, ensure that you choose a company that will provide you with quality products and service that you can trust.

Warranties for solar inverters

Looking into the warranties offered by your chosen service provider is another important factor to be considered.

Given that these devices don’t last as long as solar panels, it’s likely that you will replace your inverter at least once during the lifetime of your system. Material warranties for solar inverters generally range between 5-10 years, with certain companies offering warranties for as long 12-25 years.

The information you may receive about warranties for solar inverters online may be rather generic and over-simplified. It is, therefore, important to flesh these details out with your service provider before making a final decision.

Weather protective features

Given that your inverter will be placed outside your home or commercial property, it is important for the device to be sturdy and possesses weather-protective features.

When determining this, check your solar inverters for a hard shell or any kind of casing or technology that ensures that it is weather adaptive. Given that you’re bound to be subject to bouts of extreme weather from time to time, it is crucial that your device is able to withstand these.

In this regard, check the voltage of your PV system. This has an important effect on the inverter, given that temperature can raise and lower voltage dramatically. IP65 tech is a kind of technology that ensures solar inverters aren’t too affected by terrible weather conditions. Make sure that whichever system you opt for has the same or similar features.

Key Takeaways

Solar inverters are one of the most important parts of any solar power system. Given their function of converting direct current from the sun into energy that is useable, ensuring that your inverter is a top-notch product has to be high on your list of priorities.
