Do I need a solar inverter?
For most home and portable PV systems, you will only need one inverter if you are using either a string inverter or power optimizers for the solar array; if you use micro-inverters, you won’t require a standalone inverter all as they convert DC to AC at the panel.
What size solar inverter do I Need?
However, oversizing the array is a common practice for maximum efficiency, and a 6.6kW solar PV system typically comes with a 5kW inverter. The typical climate and sunlight available throughout the day will impact the ideal inverter capacity. The positioning of your solar PV system will also affect the solar inverter size you need to purchase.
Are solar inverters the same size?
No, solar inverters are not the same size, as the size you need will depend on the generation capacity of your solar array. There is no one-size-fits-all inverter, as the size affects the unit’s efficiency and larger inverters are more expensive. The easiest way to calculate the solar inverter size you need is to check the DC rating.
What does a solar inverter do?
Solar inverters are one of the most important components of a solar panel system. They're responsible for converting direct current (DC) electricity from your solar panels to alternating current (AC) electricity to power your appliances.
Can You oversize a solar inverter?
You can oversize your solar array up to a ratio of 1.33, or 33% larger than the inverter size. For instance, a 5kW inverter can be used for a solar PV system up to 6.6kW in capacity. This regulation is set by Australia’s Clean Energy Council to ensure all solar installations can effectively offset current and future carbon emissions.
How do I choose a solar inverter?
The first step in inverter sizing is to determine the total DC wattage of all the solar panels in your system. This information is typically provided by the manufacturer and can be found on the panel’s datasheet. Expected Energy Consumption Consider your household’s daily and peak energy consumption to ensure that the inverter can handle the load.

They also contribute to reducing the reliance on the main power grid and have a positive impact on the environment.
Micro Inverters
Micro inverters offer a unique advantage in solar power systems. Unlike traditional string inverters, each micro inverter is connected to a single solar panel, allowing for individual panel optimization. This means that even if one panel is shaded or has a lower performance due to some reason, it won't affect the overall output of the entire system. They are easy to install, highly efficient in converting DC to AC power, and provide better flexibility in system design, making them suitable for both residential and small commercial solar installations.
Roof - Integrated Photovoltaic Power Stations
Roof - integrated photovoltaic power stations combine the functionality of solar power generation with the aesthetics of building design. These stations are custom-designed to fit directly onto rooftops, replacing traditional roofing materials in part or in whole. They not only generate clean energy but also enhance the overall look of the building. With advanced installation techniques and durable materials, they can withstand the elements while providing a long-term and reliable source of electricity, making them an ideal choice for both new construction and retrofit projects.
Sizing the DC Disconnect for Solar PV Systems
A solar PV system typically has two safety disconnects. The first is the PV disconnect (or Array DC Disconnect). The PV disconnect allows the DC current between the modules (source) to be interrupted before reaching the inverter. The second disconnect is the AC Disconnect. The AC Disconnect is used to separate the inverter from the electrical grid.
