Three Phase or Single Phase Connections?

Dominic O'Leary Residential Solar, Solar Systems

Single-phase solar systems are relatively straight forward in terms of equipment and installation.

Your panels are mounted on the room and cable is run from the panels to your inverter. The inverter is connected to your switchboard and power is sent from your panels, through your inverter and into your household. 

However, for three-phase connections, this is not quite so simple. Whilst there are plenty of three-phase inverter solutions for residential premises, they are typically not battery compatible and can be much more expensive than their single-phase counterparts. This is because a three-phase inverter has to supply electricity to all three supply lines which feed power throughout your house.

If a single-phase inverter is connected to a three-phase supply without any additional technology, power is typically only supplied to one of those lines, meaning the other two supply lines still draw electricity from the grid and your system is only 1/3 as efficient as it could be. 

At P4B Solar & Energy Solutions we engage a superior technological solution called Net-Metering which allows for a single-phase inverter to spread electricity across all three phases to ensure you are getting the most out of your Residential Solar System.

In addition to better use of power on-site, this allows us to design a battery compatible system for you to ensure that you can implement a battery storage system whenever you decide you would like it.

Whether it is right now or in two years time, you won’t need to replace an inverter or add a second inverter to connect a battery to your solar system.
