Client: Residential User – Perth, Australia
Application: Whole-house off-grid backup and peak shaving
Product: 51.2V 200Ah Stackable LiFePO₄ Battery System
System Capacity: 10.24 kWh per unit (expandable up to 40.96 kWh)
Date Installed: March 2025
Project Overview
The client, a homeowner in Perth, sought a robust, scalable, and space-efficient solution to store energy from a rooftop solar system and reduce reliance on the grid. Frequent power fluctuations and rising electricity prices prompted the switch to a stackable energy storage solution.
The Solution
We provided a modular stackable LiFePO₄ battery system, each unit rated at 51.2V 200Ah (10.24 kWh). The system was configured with:
-
3 stacked units = 30.72 kWh total capacity
-
Hybrid inverter: 8 kW single-phase
-
PV input: 10 kW rooftop solar array
-
BMS & CAN/RS485 communication: Ensures safe and smart battery operation
Features Delivered
-
Modular stacking: No extra rack or cabinet needed, saving space
-
LiFePO₄ chemistry: Stable, safe, and long-lasting (>6000 cycles @ 80% DOD)
-
Expandable anytime: Future-proof design supports plug-and-play expansion
-
User-friendly display: LCD + app monitoring for energy tracking
-
Seamless solar + grid integration: Works with most inverters
Results
-
100% solar self-consumption during the day
-
Nighttime backup for essential loads (fridge, lighting, security, Wi-Fi)
-
Reduced power bills by 70% within 3 months
-
Zero downtime during grid outages
Client Feedback
“The stackable battery system was a perfect fit for our home. It looks great, saves space, and keeps our power on when the grid fails. We plan to add a fourth unit next summer.”
