Lithium Battery Backup Systems for Sandton & Midrand Homes

Lithium iron phosphate (LFP) batteries have replaced lead-acid for almost every home backup application — they are smaller, lighter, last 3–4x longer, and discharge to 90% without damage. Apple Plumbing & Electrical installs Hubble, Freedom Won and Dyness LFP battery systems from 5kWh to 30kWh across Sandton, Midrand and Northern Johannesburg, paired with hybrid inverters for full automatic load-shedding backup.

What we do

We size your battery bank to either ride out a standard 4–6 hour load-shedding window (5–10 kWh) or to run essentials all night (15kWh+). Installation includes a battery rack or wall-mount, fused DC isolators, fire-rated location assessment, BMS communication wiring to the inverter, and commissioning of charge-discharge profiles.

Signs you need this service

• Old lead-acid battery bank dying or smelling
• Existing inverter has no battery yet
• Need silent, fume-free backup (vs generator)
• Want all-night backup, not just 4 hours
