The Guide to Finding the Right Size Inverter for Your Solar Panels

When choosing solar power inverters for your residential solar panels, the first thing that you need to consider is the power output that will be generated by the solar panels themselves. You also need to consider how much power the inverter itself is able to output. By understanding the relationship and ratio of these two considerations, you will have a more thorough and comprehensive idea of which inverter is best to suit the needs of your residential solar panels. This article from Solar Power Direct will discuss a number of things to take into account before purchasing the right inverter or your home, in the hopes it will help guide you to make the right decision.

The Right Inverter for Your Solar Panels South Australia

Inverters convert Direct Current, or DC, into Alternating Current, or AC. This means that they convert the energy that the solar panels create into power that is used by the electric grid. As long as the output of energy from the panels falls within the window of the inverter’s capacity, it is considered optimal. Therefore, under sizing your inverter will mean that no matter what the output of your panels may be, your window may be cut short. This is why Solar Power Direct, like many in the industry, chooses to oversize our inverters. Oversizing inverters means that with a 5KW inverter, you can install 6.6KW of panels. Oversizing is a good idea if you think you may expand your panelling in the future. This can also save you money in the long run, as it also increases your energy production. You can overclock your inverter by 133% and still receive the solar rebate, covering up to half the cost of your solar system.

Equaling Wattage of Your Residential Solar Panels

Something else important to look into is how much continuous wattage your inverter can support. Although your residential solar panels are not going to produce a continuous and equal output of energy all day, due to the change in exposure to sunlight, it is still necessary to purchase an inverter with the capacity to handle full power output from your panels. If the full power output of your solar panels is 2000 watts, you need an inverter that can handle a continuous supply of 2000 watts, preferably more.

The Golden Rule of Thumb

The golden rule to stick to when purchasing your inverter is maintaining a 1:1 ratio of DC output to AC conversion. If your home solar system produces 3000 watts, purchase an inverter that can output 3000 watts itself. Ideally, you would want to purchase one that can handle slightly more than 3000 watts that is oversized up to 133%.

Solar Power Direct stocks a wide variety of inverters that are suitable for a range of different sized homes with different power supply requirements.
