When you decide a generator is the answer to load-shedding, the next fork is portable or standby. They're very different machines for very different budgets and needs. Here's how to choose.
Portable: cheaper, hands-on
A portable generator is wheeled out, started manually, and connected through a changeover switch when you need it. It's far cheaper and fine for backing up essentials — but it's noisy, needs fuel and manual starting, and only runs what you connect.
Standby: seamless, pricier
A standby (stationary) generator is permanently installed, often with an automatic transfer switch so it starts itself the moment the power drops and runs more of the house. It costs significantly more but is hands-off and seamless — suited to homes or businesses needing uninterrupted power.
Or skip the generator?
For everyday load-shedding, many Johannesburg homes prefer a silent, automatic inverter and battery (see generator sizing for the comparison). Generators win for heavy loads or very long outages; some homeowners run an inverter daily and keep a generator for extended ones.
Either way, connect it safely
Any generator must go through a proper changeover or automatic transfer switch installed by a registered electrician — never back-fed through a plug. We size and connect both safely. Get backup-power advice.
