CASE STUDY

Spotted on a footy jersey, now keeping a Tamworth family warm

How Kerri's family went from first email to installed battery in about a month, and stopped worrying about winter nights.

Problem to Solve

Kerri lives in Tamworth, New South Wales, with her husband and three children. The household had solar panels installed a couple of years prior but was not yet getting the full benefit from them. Electricity prices kept rising, and the bills were not reflecting the solar they were generating. With a young family and the cost of living rising, Kerri and her husband decided it was time to add a battery.

Their two priorities were clear: save money and have backup power. When a government incentive offering a discount for batteries installed before the end of July came up, it gave them the push to move forward.

Why VoltX Energy

Kerri and her husband looked at other companies before deciding. The moment that made up their mind came during a football game, when they spotted VoltX Energy on the Manly Warringah Sea Eagles jerseys. Her husband said on the spot: we're going with them. They followed up on that instinct and were not disappointed.

Experience with the VoltX Energy Team

Kerri made an initial enquiry via email and received a response within ten minutes. The team, including a consultant named CJ, walked her through how many batteries would suit her household, worked out a deal within her budget, and gave a clear rundown of the process from start to finish.

A deposit was placed within the week. About three and a half weeks later, Kerri received confirmation of the installation date. The following week, the team called to say they were ahead of schedule and offered to bring the date forward. Installation was completed about a month after first contact.

On the day, the team required Kerri and her husband to simply be at the property. The power was off for less than half an hour. The installers arrived with plenty of notice, completed the job efficiently, and walked them through the app before leaving. Kerri described them as fantastic, lovely to work with, and said they exceeded all expectations.

Day-to-Day Change

The change for Kerri's family has been immediate and practical. In Tamworth, winter is cold. Before the battery, running heaters, electric blankets, and high-draw appliances at night were something the household had to think carefully about. Now the washing machine, clothes dryer, and heaters run whenever needed, day or night, without concern about cost.

Kerri described it as the kids being able to stay warm, electric blankets running all night, and lights and TVs on without anyone worrying. Her summary: "We have our batteries; we're winning."

The App

Kerri and her husband check the app regularly. She uses it to see how much power is being drawn during the day versus the evening, and to understand when high-draw appliances like the oven, clothes dryer, and washing machine have the most impact. The installation team walked her husband through the app on the day, and he was able to explain it back to Kerri. She noted that the explanation was clear enough that even someone who is not tech savvy could follow it.

The System

BATTERY VoltX Energy 25 kWh Battery
INSTALL DATE August 2026
INVERTER 5 kW Hybrid Single phase
SUPPLIER VoltX Energy
LOCATION Tamworth, NSW

The Results

At the time of the interview, the batteries had been installed for approximately three weeks, and a full monthly bill had not yet arrived. Based on what Kerri could see in the app, the household was drawing around 3,000 watt-hours per day from the battery and only around 6 kWh from the grid in the evening. During the day, grid usage was close to zero.

Kerri anticipated a significant reduction in her next bill based on what the app was showing.

Spreading the Word

Kerri's confidence in VoltX Energy has led her to recommend the company to many of her work colleagues without being asked. She described the full experience from first inquiry to installation as a breeze, with clear communication throughout and no need to chase anyone up.

In her words: from the beginning to the end, to the installation, to the colour of the batteries, I would recommend VoltX Energy to anyone.
