What is covered
Manufacturing defects, premature component failure under normal use, and faults that were present at delivery.
What voids the warranty
- Installation by anyone other than a qualified electrician / technician. Keep the installer's receipt.
- Damage from voltage spikes, lightning, or grid surges where no protection device was installed.
- Missed scheduled services (particularly the generator 250-hour first service).
- Use of non-genuine consumables (fake oil, wrong-grade fuel, non-approved batteries).
- Physical damage, water ingress on non-IP-rated equipment, transport damage after delivery is accepted.
- Attempts to open, modify, or repair the unit outside our workshop.
- Wear-and-tear items: filters, spark plugs, oil, brushes, belts, hoses, fuses, cables.
How to make a claim
- Locate your invoice or order reference (format
MPB-ORD-XXXXXXorINV-YYYY-####). - WhatsApp us with the invoice number, a short description, and 2–3 photos or a 30-second video of the fault: open WhatsApp.
- We reply within 24 working hours with an RMA number and next steps (workshop bench-test, on-site visit, or direct replacement).
- If a workshop inspection confirms the fault, repair or replacement is at no cost to you. If the fault is outside warranty (see above), we send a written quote first.
Extended warranty
Extended cover is available on selected generators and inverters at time of purchase. Ask for a written quote before payment; it cannot be added after the sale.
