Power inverters: prices and what to check in South Africa
A power inverter in South Africa costs from about R 195 for a small 75 W unit that plugs into a car socket, to about R 7,750 for a 5 kW hybrid unit for a home battery system. A 1,500 W portable model sits between R 599 and R 2,200. For a price that matches your load, describe what you need on BlaBlaPrice and sellers will reply with their own offers.

Certification and warranty to check
If a solar system feeds into the grid, SSEG registration requires inverters that meet South African National Standard (SANS) requirements. Look for SABS approval or compliance with IEC 62109 for safety in the product documents, and ask the seller to show them. Some brands in the listings offer five-year warranties, but a warranty may cover the replacement unit and not the labour to remove and ship it. Poor ventilation can also void a warranty, so ask for the warranty terms in writing before you buy.
Summer heat and winter nights
South Africa's summer runs from December to February and winter from June to August, so October is a good month to buy before the hot season. Inverters give off heat under load, and a closed cupboard with no airflow is a poor place for one in summer. In winter the same unit may run lights, a fridge and a router through long evenings during a power cut, so size it for that evening peak, not for an average day.
How inverters are bought here
Listings show power in watts (W) or volt-amperes (VA), and battery input as 12 V, 24 V or 48 V. A 2000 VA unit is not the same as 2000 W, so compare the wattage on the label before you pay. Name your city (Johannesburg, Cape Town, Durban, Pretoria or Gqeberha) and ask sellers to quote delivery to it. Check whether the price includes battery cables, since some listings include them and others leave them out.
What to put in your request
Tell sellers what you want to connect, such as a fridge, router and lights, and add up their wattage. Give the battery voltage, say whether you need a pure sine wave unit for sensitive electronics, and say whether a used unit is acceptable. Add your budget and city. A photo of the existing battery and its label helps sellers match the input voltage and power correctly.
