What Type of Inverter Should You Choose for Your Solar Installation?
If you're thinking about installing solar power at home, then you may have assessed your roof space. You probably believe that you can introduce the right type of solar array to make it all worthwhile. You're lucky if your roof faces toward the north because you will have an unimpeded view of the sun and, consequently, there should be little to get in the way of the sun's rays. Next, you will need to determine how to install everything and what type of equipment you will need in order to take full advantage of this opportunity. As you decide, you will have to make a decision about the right type of solar inverter, so what do you need to know?
Conversion Time
If you are unfamiliar with the terminology, a solar inverter is, essentially, a tool that converts direct current (DC) into alternating current (AC). The solar panels on your roof will produce energy in DC, but before it can be used throughout your home by all of your hungry appliances, it will need to be converted by the inverter.
Solar String Inverter
Many people will choose to have the conventional string inverter, which is the simplest design and is based on the original technology. It is found in widespread use throughout Australia and is relatively easy to install, as well.
Battery Inverter
However, if you would like to take full advantage of your investment, then you may want to add a battery backup facility and, in this case, you should choose a battery inverter. This will allow you to use power at times of the day, even when the array may be shut down or disconnected. These can be connected to the national grid as well with certain safeguards, but they represent an uninterrupted power supply in most circumstances.
Best of All Worlds
There are also other forms of inverter that act as a hybrid and take into account the best of both solutions. These may also be known as "multimode" inverters, as they combine the best of the battery and string inverter into one single unit. It may be possible to retrofit a simple string inverter installation at some stage in the future should you wish. After all, these hybrid inverters may be a little more costly than you would like at the moment, and you may want to wait until they begin to come down in price.
Getting Advice
If you are unsure which solution to choose, then you should talk with your solar electrician first. They will be able to help you decide and weigh up the pros and cons of each option.
