Off-grid vs powered sites: what actually matters

As of April 2026

The debate comes up in every caravan club forum eventually. Powered site or off-grid? The strong opinions are mostly noise. What actually matters depends on your setup, your trip length, and how much you care about hot coffee before sunrise.

Here's a practical breakdown.

What "powered" actually means on SA sites

A powered site (listed as "electricity point" or "power peg" on most SA park websites) gives you a 15-amp outdoor socket - standard three-prong round-pin plug. You plug in, run an extension lead, and you have mains power at your unit.

That's it. Not a hotel. You still need your own leads, adapters, and surge protection. Parks vary on supply reliability - load-shedding was a real problem through 2022 to 2024, though it's eased since. If continuity matters, ask the park directly whether they have backup power before you book.

Powered sites cost more. Usually R50 to R150 extra per night at the same park.

When you actually need power

A 12V compressor fridge running off a 100Ah lithium battery will manage roughly 36 to 48 hours in mild weather before needing a recharge. If you're staying 4+ nights without driving daily, you'll drain it. Mains power solves that cleanly.

Caravan ACs are 220V units drawing 600 to 900W continuously. There's no realistic off-grid fix for that unless you're hauling serious solar and battery capacity. If you need AC, book a powered site.

CPAP machines and medical devices: always book powered. No debate there.

Longer stays with kids add up fast - devices, lights, a fan, the kettle. Powered removes the mental load of tracking consumption. If you're working remotely from a campsite (and plenty of people do), same answer.

When off-grid makes more sense

Two nights on a fully charged battery with a decent cooler box? You'll be fine. Off-grid sites are often the better spots anyway - tucked into bossie, away from the main thoroughfare, more private. They're not second-tier sites.

If your bakkie or trailer carries 200W+ of solar and a LiFePO4 battery, you're energy-independent in most SA conditions. Powered becomes optional. Some people specifically choose off-grid to avoid the noise cluster that forms around the power peg row at busy parks in December.

Summer in the Cape is off-grid camping at its easiest. Long days, strong sun, a modest panel charges fast. No load-shedding schedule to worry about, no shared sockets.

And if you want to camp outside developed parks - a private game reserve, a boplaas, a quieter Ezemvelo KZN Wildlife spot - off-grid capability isn't optional. It's just the entry requirement. Browse off-grid and wild camping options in the directory if that's where you're headed.

The kit that makes the difference

Battery capacity shapes everything. 100Ah AGM is adequate for a short weekend. 100Ah lithium is better - full usable capacity, longer-lived. 200Ah+ lithium gives you real room to breathe on longer stays.

Solar: a 160W flexible panel or a foldable 120W portable unit is enough for most setups in clear SA weather. Cloudy Cape winters and Berg mornings are the exception. Plan for those days separately.

A well-insulated hard-sided cooler box (Dometic, ARB, or similar) holds ice for 3 to 4 days if packed properly - pre-chill everything, ice on top, and don't open it for snacks every half hour. It draws zero amps and gives you cold storage without touching your battery at all.

A 300 to 600W pure sine wave inverter handles 220V devices from your battery bank. Not the AC - nothing fixes the AC off-grid except a proper solar setup. But it runs a laptop, charges phones, and handles a CPAP without complaint.

So which should you book?

If you're new to this and staying three nights or more, book the powered site. The R100-odd premium is cheap compared to managing battery anxiety on a trip that's supposed to be a break.

Do a few trips. Figure out what your setup actually consumes. After that, you'll have the information to decide confidently. Until then: book the power peg, and spend that mental energy on the braai instead.

If you're looking for parks with powered sites near you, the Kampreneur campsite and caravan park directory is a good place to start.
