    For a small business, load-shedding is not an inconvenience — it is lost sales, spoiled stock and frustrated customers. The good news: keeping the lights (and the till) on is very achievable with the right system. Here is how to think about it.

    Start with your must-run loads

    Backup is about what has to keep working. List it:

    • Office — points, Wi-Fi, lighting, maybe a server. A mid-size inverter and battery cover it.
    • Shop — point-of-sale, lighting, refrigeration. More capacity, often with solar.
    • Restaurant — cold storage and prep are critical; size generously.

    Why solar makes commercial sense

    Businesses use most of their power in daylight — exactly when solar produces. That makes the offset against expensive grid power strong, and paired with a battery it also rides out load-shedding. The daytime usage pattern is why commercial solar payback is often attractive.

    Compliance is not optional

    Commercial inverter, battery and solar installs tie into your supply and need an Electrical COC from a registered electrician; grid-tied systems also need SSEG registration. Compliance protects your lease and insurance.

    Frequently Asked Questions

    It depends on what must keep running. An office needs points, Wi-Fi, lighting and maybe a server — a mid-size inverter and battery suffice. A shop with point-of-sale and refrigeration, or a restaurant with cold storage, needs more capacity and often solar to keep running cost down. The first step is listing your essential, must-run loads.
