There is so much information around the internet about 3 phase inverter for solar, so much so that it actually is confusing and you don’t really know what to believe. This is why it is important to do your research as the first step, but also get in contact with professionals who will take the time to explain things to you in a way you will understand.
Solar panels are very popular these days; there are a number of government incentives as well as reducing your power costs and using a renewable energy source. There are different ways that getting solar to work on your property and one of them is if your house has a 3-phase supply.
It is possible for this to be connected and you actually have a couple of options of how to do this, and it’s up to you and the company you choose to get your solar set up from to finalise the best option. The 3 options you can choose from include:
- You can connect your solar system to all 3 of the phases by using 3 different single-phase solar inverters.
- You can also connect your solar system to one of your supply phases using a single-phase solar inverter.
- Finally, you can connect your solar system to all 3 phases of supply with one single 3-phase solar inverter.
An expert will be able to provide more clarity on the best option for you to move forward with. But there are a few factors that come into play that will help you shape your decision. Have a read on below at some of these factors you should consider:
3-Phase Load Balancing
It is important to note that sometimes the demand between the different phases will not be completely balanced. This means there could be additional load on one compared to the others, or even on two compared to the final one.
Looking from a financial perspective, if you are getting solar financial payback, then you don’t really need to worry. This is because your billing will be summed up in total. In saying that, you still do want to get more of a balance from a technical perspective, because this is a good sign that things are working well and you are getting good power quality.
If you have solar panels on your property, you obviously want them to work, and if the power isn’t balanced between the 3 phase inverters then it could cause them to trip out and remain unstable and unreliable.
A lot of people choose to move onto solar because of the discounted pricing attached to this renewable energy source. When you generate solar energy on your property, you want to be the one that is using it. Here, it is important to note that if you have a 3-phase inverter, through any of the different options listed above you will not lose out.
It should be that all 3-phase meters taken into consideration the total of all the electricity being used on your property through all the different phases, then you subtract that by the quantity of total solar energy that has been able to be generated to finalise the total billing cost.
Things can get a bit tricky here and some companies can set it up incorrectly, so you end up having to pay more. So, that is why it is really important you continue to do your research and talk to a number of different companies to see their process of dealing with a 3-phase inverter.
