Stock Accuracy: Returns halved after a sizing panel

GF Commerce Desk · 22 Jan 2026 · 6 min read

Our returns desk keeps honest statistics, and they point at an uncomfortable truth: customers rarely return inverters because the hardware failed. They return them because the hardware was never going to fit their load.

Sizing to the surge, not the bill

A 3.5kVA inverter carries a home comfortably until the borehole pump starts. Motors draw multiples of rated power on start-up; size to survive the worst simultaneous start.

Our product pages publish surge ratings precisely so this arithmetic is possible before checkout.

The battery-voltage trap

Right inverter, wrong-voltage battery bank accounts for a quarter of category returns on its own. Above 3kW of sustained load, 48V stops being a preference and becomes physics.

Buy the audit before the inverter. Both are in the store.

What it means for your next decision

Read against NAFDAC where applicable, the practical takeaway is simple: the operators who win here are the ones who measure 214 stores supplied before they commit capital, not after. Greyfusion publishes the assumptions behind these numbers because confident analysis survives scrutiny.

If this maps to something you're planning, the eCommerce desk answers with a working model, not a brochure — talk to us before the decision, not after.
