Battery Backup Power: Resilience When You Need It Most
Power outages can happen without warning—storms, equipment failures, or grid issues leave families without heating, refrigeration, or communication. A battery storage system with solar provides seamless backup power, keeping your home running 24/7.
The Growing Risk of Blackouts
Melbourne’s western suburbs experience occasional grid outages due to:
- Severe weather events and storm damage
- Aging grid infrastructure in growth areas
- Planned maintenance outages
- Vehicle accidents affecting power lines
A battery system protects your family and property. When the power goes down, your battery system automatically kicks in—no disruption, no stress.
How Backup Power Works
Hybrid Inverter Technology
Your hybrid inverter continuously monitors grid status. When the grid fails:
- Inverter detects the outage instantly (within milliseconds)
- Isolated circuits switch to battery power automatically
- Essential loads continue uninterrupted (lighting, refrigeration, communications)
- Solar panels recharge the battery during the day
- Normal operation resumes when the grid returns
No Manual Intervention Needed
The switchover happens automatically—no need to flip switches or start a generator. You’ll barely notice the outage.
What Stays On During a Blackout?
You have full control over which circuits stay powered during outages.
Essential Loads (Typical)
- 🧊 Refrigerator and freezer (food preservation)
- 💡 Lighting in key rooms
- 💧 Water pump (if applicable)
- 📱 Communications devices and internet modem
- 🌡️ HVAC systems (heating/cooling)
- ⚕️ Medical devices (if needed)
Non-Essential Loads (Typically Shed)
- 🍳 Electric oven and cooking appliances
- 🚿 Hot water systems
- 🧺 Laundry equipment
- ❄️ Air conditioning (unless critical)
Battery Capacity & Outage Duration
How Long Can You Actually Run?
Here’s what realistic backup times look like:
| System Size | With 2kW Load | Practical Runtime |
|---|---|---|
| 5 kWh battery | ~2.5 hours | ~2.5 hours backup |
| 10 kWh battery | ~5 hours | ~5 hours backup |
| 15 kWh battery | ~7.5 hours | ~7.5 hours backup |
With solar panels charging during the day, a typical system can run indefinitely during daylight hours and provide 8+ hours of evening/night backup.
Real-World Scenarios
Scenario 1: Storm & Outage ⛈️
8:00 AM: Storm damage causes blackout. Your system detects the fault and switches to battery instantly. Lights, refrigerator, and internet remain on all day as solar panels charge the battery.
6:00 PM: Power restored. Your family experiences no disruption—while others are in the dark.
Scenario 2: Extended Outage (24+ Hours) 🌙
Day 1: Full battery power plus solar charging. Night 1: Battery supports essential loads. Day 2: Solar charges again. Your system provides extended resilience while neighbors are without power.
Scenario 3: Peak Rate Periods 📊
Evening peak rates (5–9 PM) are expensive. Your battery discharges to power essential circuits, then recharges from solar the next day. Result: Reduced peak demand = Lower bills.
