Frequently Asked Questions

What size generator do I need for a 3-bedroom house?

−

For a typical 3-bedroom house in Nigeria, a 3KVA to 5KVA generator is recommended. This can power a refrigerator, ceiling fans, LED lights, TV, and a small split AC unit simultaneously.

What warranty does Sumec Firman offer?

All Sumec Firman products come with a 12-month manufacturer's warranty. Our shop provides warranty support directly — no need to visit a third-party service centre.

Do you deliver outside Lagos?

Yes, we deliver nationwide across Nigeria. Delivery to Lagos is same-day or next-day. Other states take 1 to 3 business days via GIG Logistics and DHL partners.

Can I return a generator if it has a fault?

Yes. We have a 7-day return policy for faulty or wrongly delivered items. Products must be in original packaging and unused. See our full Returns Policy page.
