What is a 3 phase solar inverter?

3 phase solar inverter start at about 5kW so if you want an inverter smaller than 5kW you are looking at single-phase. If you want a system with an inverter larger than 5kW then your local Electricity Network may insist that you use more than one phase. The best way to do this is to use a 3 phase inverter.

How do I connect my solar system to a 3 phase inverter?

Your 3 options are: 1) connect your solar system to only one of your supply phases with a single-phase solar inverter. 2) connect your system into all 3 phases of your supply with a single, 3-phase solar inverter 3) connect your system into all 3 phases with 3 separate single-phase inverters.

Should I buy a 3 phase inverter?

So if you have an issue with voltage drop – a 3 phase inverter is a good solution. Otherwise, if you are installing a system and have the choice of one single-phase meter, or one 3 phase meter, the choice is yours. The advantage of a 3 phase meter is that it is a more robust system (lower voltage drops, phases balanced).

How do I install a solar inverter?

1) connect your solar system to only one of your supply phases with a single-phase solar inverter. 2) connect your system into all 3 phases of your supply with a single, 3-phase solar inverter 3) connect your system into all 3 phases with 3 separate single-phase inverters. Here’s what you need to consider in deciding which option to go for:
