Plug-In Solar for Bushfire Resilience: What to Store and How

Australia's bushfire seasons stretched from October to April in the Black Summer of 2019-20 and have not shortened since. Rural and semi-rural residents across VIC, NSW, SA and WA are increasingly configuring portable solar + battery kits as bushfire resilience. This guide covers what actually keeps working when the grid drops for 3–7 days during a fire event.

What plug-in solar can and can't do

Can: run essential loads (fridge, lighting, phones, CB radio, medical devices, small fan) for days. Cannot: power air conditioning, hot water systems, electric ranges, or run a well pump without careful sizing.

For fire-active periods, essentials-only is the right frame.

The resilience setup

• 400W foldable or rigid solar panels (deploy after front passes, not during — burning ash destroys panels)
• 2 kWh LiFePO4 portable power station
• Solar MPPT input already built into modern power stations
• Pre-storm: fully charge the battery 48 hours ahead when smoke is visible on horizon

Typical daily draw during evacuation-ready mode

2 kWh battery sustains ~1 day; 400W solar recharges 1,800 Wh/day even through smoke-filtered light. Sustainable indefinitely as long as sun eventually penetrates.

Panel storage during the fire itself

Bring panels indoors or into a fire-proof shed during active fire threat — flying embers destroy exposed panels and can start secondary fires from panel-frame heating. Redeploy once immediate threat has passed.

What NOT to skip

• Battery indoors, not in garage — LiFePO4 handles heat OK but ash intake is bad for cooling vents
• Backup phone charger independent of the main battery — always keep one 20,000mAh USB battery charged separately
• Written evacuation plan — solar setup is Plan A; drive-out is Plan B
