Single Phase Solar Systems in NSW

1. SolarEdge Systems up to 5kW

All solar systems smaller than 5kW are installed with a single phase inverter, even if you have three phase power.

When your solar installation is completed your existing meter needs to be replaced with a new bi-directional solar meter (Solaray will typically organise this for you). If you have three phase power this meter will be a three phase digital meter, and it will replace your existing meter (or meters if you have three old analogue meters). Typically your new meter will be the Atlas EDMI polyphase meter or similar.

When this meter is programmed, it is done in such a way so that it records the consumption across all three phases before it sees any solar power as surplus. The meter reconciles the three phases and records your total usage as one total before recording any excess solar power. More information is available here:

 2. SolarEdge Systems from 5kW up to 6.5kW

The energy distributors in Sydney have a regulation that the largest inverter you can install on a house with single phase power is 5kW.

A SolarEdge system can be oversized by around 30%, which means that on a 5kW SolarEdge Inverter, we can install a panel array of up to around 6.5 kW.

By supersizing the panel array, the Solaray design team are able to maximise system efficiency, as the system reaches its maximum output sooner and then stays there for as longer. By adding additional solar panels to a SolarEdge inverter, your system will generate more power in the morning, reach maximum output sooner, work at maximum output for longer and produce more power later into the afternoon. The downside is that on the best days of the year, the system’s output will be slightly clipped for a short period of time. By adding panels to your SolarEdge System, we can significantly increase system output and distribute this output more evenly across the day.

In winter and on days when the weather is not ideal for solar, over-sizing the inverter will give you more power across the day as the output will typically not be clipped as illustrated below:

On the days where some clipping does occur, the loss is, for the most part, made up by the fact that you have more panels outputting more power in the morning and during the afternoon. Furthermore, the STC government rebate is based on the size of the panel array, not the inverter, so the price of the additional panels is significantly offset by the increased government rebate.

 1. SolarEdge Systems from 6.5kW up to 10kW

Revolutionary SolarEdge technology has completely changed the game for single phase houses in NSW. Up until recently, we could only install a 5kW system, however thanks to export limitation we are now able to use the SolarEdge 7.3kW single phase inverter and limit the amount of excess solar power that is sent out to the grid. This allows us to install up to a 10kW solar system, as the 7.3kW inverter can be oversized by up to 30%.

Limiting the amount of excess solar power does not have an impact on the amount of solar power fed into the home. This allows you to have the full benefit of a larger system, and then any solar power that you don’t use is limited to 5kWs. Most Solaray customers are now looking at battery storage to further increase the benefit of their system by storing any excess solar power to then use when needed, such as in the evening or on rainy days.

This functionality is a part of the SolarEdge consumption monitoring software, that offers households full oversight of their system’s performance, as well as how much energy is being used in the home.
