Understanding Blackout Protection in Perth

While Perth's electricity grid is generally reliable, power outages can occur due to storms, heatwaves causing network overload, or maintenance work. A battery with backup capability provides security during these events.

Not all batteries offer backup: Many batteries are grid-tied only and will not work during an outage. Look for batteries with "backup" or "off-grid" capability.

Partial vs whole-home backup: Most systems provide backup to a protected loads panel (selected circuits) rather than the entire home. This extends backup duration.

Essential Loads to Prioritize

Critical (Always Include)

Refrigerator/freezer (preserve food)
Medical equipment (if required)
Security system and garage door
Internet router and phones
1-2 lights per room

Optional (If Capacity Allows)

TV and entertainment
Computer and office equipment
Microwave and kettle
Fans or small heater
Hot water system (heat pump)

Maximizing Backup Duration

Start with a full battery: Set your system to charge to 100% before forecast severe weather
Reduce non-essential loads: Turn off computers, TVs, and appliances you don't need immediately
Use high-draw appliances strategically: Avoid running ovens, clothes dryers, or air conditioners during backup
Consider solar recharging: With a hybrid inverter, your battery can recharge from solar during the day even during an outage
Size appropriately: If backup is critical, choose a larger battery (16kWh+) or consider a second unit
