How to Choose the Best Solar Inverters in Perth for Your Home?

May 10, 2023

If you are planning to install a solar power system in your home or business, you will need the best solar inverters to convert the direct current (DC) electricity produced by the solar panels into alternating current (AC) electricity that can be used by your appliances and devices. But how do you choose the best solar inverter for your needs? Here are some tips to help you make an informed decision.

Tips to Choose the Best Solar Inverters

Here are some tips to find the top solar inverters.

1. Know the types of solar inverters

There are three main types of solar inverters: string inverters, microinverters, and power optimizers. String inverters are the most common and affordable option. They connect multiple solar panels in a series and convert the DC electricity into AC electricity at a central location. Microinverters are small devices that attach to each solar panel and convert the DC electricity into AC electricity at the panel level. Power optimizers are similar to microinverters, but they only optimize the DC electricity at the panel level and send it to a central inverter for conversion. Expert solar companies provide suitable type of top solar inverters in Perth for you.

2. Consider the size and capacity of the solar inverter

The size and capacity of the solar inverter should match the size and output of your solar panel system. If the inverter is too small, it will not be able to handle the power generated by the panels and may overload or shut down. If the inverter is too large, it will waste energy and money. The size and capacity of the inverter are measured in watts (W) or kilowatts (kW). To find the right size and capacity for your system, you can use this formula: Inverter size (kW) = Solar panel system size (kW) x 0.8. For example, if you have a 5 kW solar panel system, you will need a 4 kW inverter.

3. Compare the features and specifications of different solar inverters

Different solar inverters have different features and specifications that affect their performance and functionality. Some of the features and specifications to look for are:

Efficiency: This is the ratio of AC output power to DC input power. The higher the efficiency, the more power the inverter can deliver to your home or business. The average efficiency of solar inverters ranges from 90% to 98%.

Maximum power point tracking (MPPT): This is a feature that allows the inverter to adjust the voltage and current of the DC electricity to maximize the power output of the solar panels. MPPT can increase the efficiency of the system by up to 30%.

Warranty: This is the period of time that the manufacturer guarantees the quality and performance of the inverter. The warranty can vary from 5 to 25 years, depending on the brand and model of the inverter. A longer warranty can give you more peace of mind and protection.

Monitoring: This is a feature that allows you to track and monitor the performance and status of your solar panel system and inverter. Some inverters have built-in monitoring systems that can be accessed through an app or a web portal. Some inverters require additional devices or software to enable monitoring.

4. Choose a reputable and reliable brand and installer

The quality and reliability of your solar inverter depend largely on the brand and installer you choose. You should do some research and compare different brands and installers based on their reputation, experience, reviews, certifications, and customer service. You should also check if they offer after-sales support, maintenance, and repair services for your solar inverter.
