Understanding Off-Grid Solar Systems

At Excel Power, we often service issues relating to complex, untidy, and borderline dangerous off-grid solar systems.

These systems are proof that investing in quality products provided and installed by certified tradespeople is the only way to ensure a safe, simple, and reliable off-grid system for your home, property, or business. People rely on these systems for their everyday work and lifestyle, so it is important that the system meets their needs, lasts, and is warranted and serviced for many years in the future.

To ensure you’re getting the most from your investment, there are several things to consider: 

  • What your desired installer can offer, especially beyond the point-of-purchase 
  • Your minimum capacity requirements 
  • Products and brands and how they differ from one another 

At Excel Power, we recognise that each customer has different needs and requirements and assess each client’s off-grid solar project individually.

Our team performs personalised consultations with our customers prior to purchase to ensure we recommend the right products for your power needs. We consider your power usage, system expandability, and solar panel layout considering times of day and seasons. During this consultation, we also provide expert knowledge and recommendations to help you maximise your system efficiency and save power consumption.

The Brands We Trust to Deliver Quality Solar


The Tesla Powerwall is a revolutionary home battery system that ensures you always have access to power. With easy installation and quick set-up speed, the Tesla Powerwall works with your solar panels to store excess solar energy that you can utilise later. Other benefits include:

  • a sleek, compact and simple wall-mountable design that improves your property value
  • Ability to expand up to 10 Powerwalls on one system
  • Weatherproof and touch-safe
  • 5kW continuous output per Powerwall
  • 24/7 mobile monitoring
  • 10-year warranty with unlimited cycles 

Unlike cheaper solar panels systems that utilise a string inverter setup, Excel Power’s Enphase micro-inverter setup increases your system’s overall effectiveness as each panel’s output doesn’t impact the system’s overall performance. There are numerous reasons as to why Enphase systems benefit off-grid users, including:

  • Enphase uses a high-quality no-string microinverter system to eliminate the chance of a single point of failure and reduces potential down time. 
  • The micro-inverters operate independently to ensure each panel performs to its maximum potential.
  • Enphase systems have the flexibility to enable easy expandablity. 
  • As opposed to string inverter setups that can only run in the same direction, our micro-inverters can be placed on panels anyway, almost anywhere. This allows us to utilise any available space to increase the effectiveness of your system. 
  • With live system monitoring, our Enphase systems come with top-of-the-line support and 10-year warranty. 

As award-winning Platinum Installers of Enphase products, we have proven reliability installing Enphase systems and receive top-priority product allocation, technical support, and executive access for our customers.
