5kW All-in-One ESS Helps Homeowners Reduce Electricity Costs by 72%

Project Overview

With rising electricity prices and increasing grid instability, residential customers in Australia are looking for smarter ways to maximize solar energy utilization and reduce household electricity bills.

A local solar installation company in Australia contacted Zelinco Energy to source a reliable All-in-One Energy Storage System for residential applications. Their customers needed a simple, integrated solution that could replace traditional battery + inverter systems, reducing installation complexity and after-sales maintenance costs.

Compared with conventional separated systems, the customer wanted a solution that could provide:

• Easy installation for local installers
• Automatic backup power during grid outages
• Higher solar self-consumption rate
• Flexible battery expansion capability

Customer Challenges

1. Complex installation of traditional battery systems

Traditional residential storage solutions require separate installation of:

• Hybrid inverter
• Lithium battery modules
• Communication systems
• Additional wiring and protection devices

This increased installation time and required professional technicians.

2. Frequent power outages affected daily life

Severe weather conditions occasionally caused grid interruptions, affecting:

• Household lighting
• Refrigerators
• Air conditioning
• Home appliances

3. Low solar energy utilization

During daytime, excess solar power was exported to the grid at low feed-in tariffs, reducing the economic benefits of rooftop solar systems.

Customized Energy Storage Solution

Based on the customer’s residential application requirements, Zelinco Energy provided a complete Residential Energy Storage Solution based on the XPF series All-in-One Energy Storage System.

The system integrates battery storage, hybrid inverter and intelligent BMS management into one compact unit, providing a plug-and-play energy solution for residential users.

• Lighting
• Refrigerator
• Internet equipment
• Essential household appliances

for more than 12 hours.

3. Higher solar self-consumption

Solar self-consumption rate increased from:

45% → 91%

Monthly electricity costs reduced from:

AUD 320 → AUD 89

4. Flexible capacity expansion

For larger residential applications, customers can expand capacity through:
