Prices can vary based on the brands chosen and installation complexity. A complete 5kW hybrid inverter system with a 5kWh lithium-ion battery, including professional installation and a CoC, typically costs between R65,000 and R90,000 in the Randburg area.

A modern lithium-ion (LiFePO4) battery can last over 10 years and handle thousands of charge cycles. A lead acid battery will likely need replacement within 2 to 3 years, making lithium far more cost effective in the long run. Yes, absolutely.

It is required by law and essential for your home insurance. A CoC is a legal document issued by a registered electrician certifying that your installation is safe and complies with South African electrical regulations (SANS 10142-1).

Any system that connects directly to your home's wiring must be installed by a qualified electrician to be safe and legal in South Africa. A DIY installation will void your home insurance and your equipment warranties. No.

This is one of the most common questions we get. For essential loads (lights, TV, router, a few plugs), a 3kW or 5kW inverter is usually sufficient. For homeowners in Randburg, to run heavier appliances like a kettle or microwave, you would need a larger 8kW+ system and a substantial battery bank.
