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 Benoni area.

This is one of the most common questions we get. For homeowners in Benoni, yes, absolutely. 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.

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) in the Benoni area.

A DIY installation will void your home insurance and your equipment warranties. No. This is worth noting for Benoni homeowners. 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.

To run heavier appliances like a kettle or microwave, you would need a larger 8kW+ system and a substantial battery bank. For homeowners in Benoni, for essential loads (lights, TV, router, a few plugs), a 3kW or 5kW inverter is usually sufficient.
