When You Might Miss Mains Power
We often don't realise how much we take mains power for granted until it's suddenly unavailable. There are a few situations where this hits hardest:
- When you're camping or spending any length of time in a remote area without reliable mains power
- When you need to keep essential electronics running during a blackout - your desktop computer, for instance
- When you need your surveillance system to keep functioning during a power outage
Once you've identified what worries you most about losing access to mains power, you can prepare for any contingency.
Your Power Alternatives
There's no single right answer - the best solution depends on how much power you need, how long for, and where you are. Here's how the main options stack up:
- Petrol generator: For maximum output with minimum hassle, this is usually the best option. It can push power for as long as you keep topping up the fuel. The downsides are noise, smell, and environmental impact.
- Solar with battery and inverter: A solar array paired with a battery and inverter is a clean, quiet option well suited to outdoor adventures or the garden shed. It needs sunlight and time to charge, but runs silently with zero fuel costs.
- Wind turbine: A capable option in the right location - wind turbines can produce up to 2000W at 48V in strong winds. Limited to areas with a steady breeze.
Keeping Security Running During a Blackout
If your greatest concern is burglars taking advantage of a blackout, an uninterruptible power supply (UPS) is the perfect way to keep your surveillance system running. A UPS kicks in instantly when mains power drops - there's no delay and no gap in coverage.
