Installing a 99kW Commercial Solar System with Enphase IQ8 Microinverters

Welcome to Richmond, New South Wales, where we’re upgrading an outdated solar system; a well-used 6.6kW string inverter solar system.  

In this article, we’ll get into the challenges, strategies, and technologies involved in installing a new 100kW (kilowatt) solar system with three Tesla Powerwall 2 batteries.  

Installation Challenges  

Removing the faulty 6.6 kW string system was where our team started.

The installation site posed numerous challenges. Additional days are always required by our team for roofs that have a pitch of 25° or greater. This roof was 38°!

The installation process slows down on steeper roofs. A steep roof requires careful planning and follow-through to make sure everyone on the team is safe. Our team works hard and efficiently, and safety is a key concern – for everyone.  

Fortunately, it was a tin roof. If you’re interested in learning more about how tin roofs are a little easier on our installation teams, you might want to check out the following article titled, How Does Your Roof Affect Your Installation?

Safety Measures   

Ensuring the safety of our team and the installation site is our top priority. In addition to edge protection and safety harnesses, our team undergoes rigorous training to handle the unique challenges of working on a steep tin roof. We adhere to strict safety protocols and procedures to protect our people and your home.  

The roof is unique in that it has 12 roof faces (we’ll get into that shortly). The pitch of each face is steep enough to require the team to use the rails as steps as they go about their work. They just step cautiously.

Why Enphase Microinverters 

Enphase microinverters play a crucial role in optimizing the performance and reliability of the solar system. Unlike traditional string inverters, which can suffer from shading issues and single point of failure, Enphase microinverters offer individual panel optimization, ensuring maximum energy production even in challenging conditions.  

As you can see in the video, there are some beautiful trees surrounding the buildings. Unfortunately, shading can be the kiss of death for solar systems. Solar only produces power when the sun can shine on the panels – unobstructed.

Because of this, our team planned the design with shading in mind. Which made it a good fit for one of our favourite pieces of solar technology: the Enphase IQ8AC microinverters. Microinverters make certain that energy production is maximised, and the customer can start saving on their electricity bills right away.

Panel Installation  

Installing a 100kW solar system across 12 roof faces was no small feat. Each roof face presented its own set of challenges. Some faces were smaller than others, requiring the staggered design you can see in the video.  

Access to each roof face is different as well, so the installation process changed each time and new safety considerations were evaluated and solutions were put into place.

Unique Site Features  

One of the most notable features of this installation site is its multiple buildings and solar-boosted hot water systems.  

Integrating solar panels across three buildings requires meticulous cable management to ensure efficient power distribution. Our team rises to the challenge, planning and executing cable routes with precision to minimize visual impact while maximizing performance.  

Additionally, the presence of solar-boosted hot water systems adds complexity to the design and installation process, requiring careful coordination to ensure seamless integration with the new solar system.

Switchboard and Battery Installation 

At the heart of the solar system lies the main switchboard, where power distribution and battery storage are managed. On this site, our team installed three Tesla Powerwall 2 solar batteries. Installing commercial-grade equipment, including the Tesla Gateway and Powerwall Stacker Kit, requires careful consideration of space and functionality.  

Our team leverages the Tesla Stacker Kit to optimize battery placement and streamline installation. The result is a seamless integration of battery storage with the solar system, providing our clients with reliable backup power and enhanced energy independence.
