A solar inverter is a device that converts the direct current (DC) electricity generated by solar panels into alternating current (AC) electricity, which is used by most home appliances and the electrical grid.

The main types of solar inverters are:

• String inverters: Connect multiple solar panels in series.
• Microinverters: Attach to individual solar panels, optimising performance.
• Power optimizers: Used with string inverters to improve efficiency at the panel level.
• Hybrid inverters: Integrate battery storage capabilities, allowing energy use during outages.

The cost of a solar inverter can vary widely based on the type and brand and additional factors like the system size and installation complexity can also affect the overall price.

The best solar inverter for your system depends on system size, shade conditions, battery storage and budget.

Most solar inverters have a lifespan of 5 to 15 years, although some high-quality models may last longer. It’s important to check warranties, which typically range from 5 to 25 years.

Standard solar inverters without battery backup will shut down during a power outage to protect utility workers. Hybrid or battery-based inverters can continue to supply power if equipped with battery storage.

Solar inverters generally require minimal maintenance. However, regular inspections for dust buildup and cooling fan functionality are recommended, especially in dusty or hot environments.

The efficiency of a solar inverter is important because it determines how much of the DC power generated by the solar panels is converted to usable AC power. Higher efficiency translates to more energy produced and saved on electricity bills.

Solar batteries capture surplus energy generated by your solar panels for future use. They provide power to your home when the sun isn’t shining, such as during the night or on cloudy days. Essentially, they are large batteries specifically designed to complement solar energy systems.

Solar batteries store energy when your panels produce a surplus. This stored energy is utilised when your panels aren’t generating sufficient electricity, decreasing your dependence on the grid.

AC-coupled batteries store energy that has already passed through an inverter, making them perfect for existing solar setups. In contrast, DC-coupled batteries, such as the Powerwall 3, connect before the inverter, offering greater efficiency for new installations.

Battery degradation is influenced by factors such as temperature, usage patterns, and depth of discharge. High-quality batteries tend to degrade more slowly, allowing them to maintain their capacity for many years.

Most solar batteries have a lifespan of 10 to 15 years, depending on their quality and usage. Warranties typically cover performance and degradation for this duration.

Integrating a solar battery allows you to store excess energy generated by your solar panels for later use, enhancing your energy independence. It can help you reduce reliance on the grid during peak hours or power outages, optimise self-consumption of generated energy, and provide backup power when needed. However, it may require an inverter that can handle battery storage, and there may be additional installation costs.

Yes, in most cases, you can expand your energy storage capacity by adding more batteries to your existing solar system. This may involve upgrading the inverter and ensuring the system is compatible with the new batteries
