Inverter or Fixed-Speed? Choosing ACs for Weak Grids

27 August 2026 · JML Market Team

The West African power reality

Across the region, mains voltage commonly swings between 150V and 260V, outages are frequent, and many shops and homes run on generators several hours a day. Any AC range you import has to survive these conditions — and your customers will ask exactly how many watts each unit draws on a generator.

Where inverters win

Inverter compressors soft-start without the 3–5× startup surge of fixed-speed units, so they run happily on smaller generators and unstable voltage. Once running, they modulate instead of cycling on/off, cutting electricity use by roughly 30–40% in real conditions — a decisive argument where power is expensive or comes from diesel. Inverter models also pair well with growing solar installations.

Where fixed-speed still makes sense

Fixed-speed units cost significantly less to buy, use simpler control boards that any local technician can repair, and remain the volume seller in entry-level retail. JML stocks both: fixed-speed R32 wall splits for price-driven retail, and inverter floor-standing and multi-split systems for commercial and premium buyers.
