But is an inverter replacement or upgrade right for you?

Many homeowners have benefited from upgrading their PV system inverter. 

There are a number of different reasons to take that step. 

To help you decide, we want to be able to offer you the very best service and advice. Often it is difficult to speak to people at 'parts shops' so we have made it our business to be available to you. 


Reasons to upgrade


Inverter or Solar PV System Failure

If your Solar PV system is suffering from underperformance and is out of warranty, it could be the right time to consider an upgrade. 
If that is the case, have someone check the entire installation for physical or other types of damage. The inverter's uptime and warranty can be checked and its software can be used to isolate any problems. 

Expanding PV System Functionality

An upgrade to a new inverter gives you the opportunity to expand the functionality of your PV system in-line with new innovations brought about by any one of our brands.  

Increase Efficiency (and FiT revenue)

We are experts at solar installation and design. We use multiple software applications to design systems for home and business. 

Using this, we can work with you to ensure you have exactly what you need for your home system.

Charge Your EV

SolarEdge have created the world's first EV Solar Inverter. 

Use excess solar energy to charge your electric vehicle up to 2.5 times faster than a standard EV charger through an innovative solar boost mode that utilises grid and PV charging simultaneously. 

By installing the EV charging inverter, you’ll benefit from the reduced hassle of installing separately a standalone EV charger and a PV inverter, as well as integration with the SolarEdge monitoring platform
