Warranty on consumer electronics is primarily administered by the original manufacturer or their authorised Nigerian service centres. Gramowatt acts as your point of purchase and will assist in initiating and processing manufacturer warranty claims on your behalf.

• Defects must be reported within the product's stated warranty window
• The product must be returned in its original or safe packaging
• Proof of purchase from Gramowatt Technologies Ltd is required
• Products with physical damage or evidence of tampering will not qualify
• Gramowatt does not directly repair electronics unless we hold a service agreement with the brand

Electrical accessories such as cables, sockets, switches, circuit breakers, and conduits are covered under a 3–6 month replacement warranty from the date of purchase, for verified manufacturing faults.

• Item must not have been subjected to improper use or overloading
• Defective items are replaced — no cash refunds unless the item is out of stock
• Batch faults affecting multiple items are handled on a case-by-case basis
• Items installed by a third party (not Gramowatt) are the responsibility of that installing party

• Batteries must be operated within the specified voltage and current range
• Deep discharge below the manufacturer-specified minimum level voids the warranty
• Batteries stored or operated in excessive heat (above 45°C) are not covered
• Warranty covers capacity loss beyond normal degradation as defined by the manufacturer
• Physical swelling or casing rupture from overcharging is reviewed on a case-by-case basis

Panels carry the manufacturer's performance and product warranty. Gramowatt facilitates claims on your behalf but is not the primary warranty provider for panels. Customers are encouraged to register their panels directly with the manufacturer where applicable.

Inverter or controller faults must be reported promptly. Our technicians will diagnose whether the fault is installation-related (covered by us) or a hardware defect (covered by the manufacturer). Gramowatt will manage the repair or replacement process with the supplier on your behalf throughout the warranty period.

• Damage resulting from acts of God — flooding, lightning, earthquake, or fire
• Power surge or voltage spike damage, including from NEPA/PHCN grid instability
• Repairs, modifications, or tampering by persons not authorised by Gramowatt
• Failure to follow product care or usage instructions provided at point of sale
• Use of incompatible accessories or components not recommended by Gramowatt
• Cosmetic damage (scratches, dents, discolouration) that does not affect functionality
• Products with removed, defaced, or altered serial numbers or warranty stickers
• Normal wear and tear or consumable parts (fuses, light bulbs, filters)
• Damage from improper transportation or handling by the customer after delivery
• Loss of data or software configurations in smart devices or inverters
• Issues arising from use of non-genuine replacement parts
• Products purchased from third parties and not directly from Gramowatt Technologies Ltd

• Annual inspection of wiring, sockets, and circuit breakers
• Testing of RCDs (Residual Current Devices) and safety switches
• Load balancing and distribution board review
• Identification and remediation of electrical fault risks

• Read and follow all product user manuals and care instructions provided at purchase
• Retain proof of purchase for the full duration of the warranty period
• Avoid tampering with, disassembling, or modifying installed systems
• Keep installation areas clean, accessible, and properly ventilated
• Report unusual behaviour — strange sounds, smells, error codes, or performance drops — to Gramowatt promptly
• Not connect appliances or loads beyond the designed capacity of the installed system
• Ensure that only Gramowatt-authorised technicians perform maintenance or repairs during the warranty period
• Notify Gramowatt before relocating any installed equipment
• Protect outdoor installations from unnecessary exposure where feasible

For critical system failures — such as complete solar system shutdown, electrical faults, or safety hazards — contact us immediately on 08035848943. Emergency response is subject to technician availability and your location within Nigeria.

Products or installations outside their warranty period can still be serviced by our technical team under the following terms:

• A diagnostic or call-out fee applies for on-site visits
• A full cost estimate is provided and agreed upon before any repair work begins
• Spare parts are sourced from our approved suppliers
• A 3-month workmanship guarantee applies to all out-of-warranty repairs carried out by Gramowatt
• Gramowatt reserves the right to decline repair of unsafe or severely compromised systems
