More complex jobs like a main board replacement can range from R4,000 to over R15,000. Simple repairs like a fuse or fan replacement can cost between R800 and R2,000.

A Kandua professional diagnosis is the only way to be certain. A rapid drop in backup time usually points to the batteries, and this is especially relevant for Randburg residents. Error codes, strange noises, or a total failure to power on often indicate an inverter fault.

Standard lead-acid batteries typically last 2-5 years. Modern Lithium-ion (LiFePO4) batteries can last 8-15 years with proper care. Lifespan depends on the type and usage.

If the repair cost is more than 60% of the price of a new, comparable unit, it's usually more cost-effective to replace it. A new inverter will come with a full warranty and better efficiency. It's always worth getting a professional assessment for your specific needs.

Always replace all batteries in a bank at the same time. This is strongly discouraged. For homeowners in Randburg, old batteries will reduce the performance and shorten the lifespan of the new ones.
