There is no single honest price for every 5kVA solar system in Nigeria. A quotation with a small battery and no panels can be called 5kVA, and so can a complete hybrid system with a large lithium bank, a properly sized PV array and full protection. The inverter label is only one part of the system.
What a 5kVA inverter can tell you
The inverter rating indicates how much load it can supply at once, subject to the model's real-power rating and surge capability. It does not say how many hours the system will run. Runtime comes from usable battery energy and the appliances drawing power.
The five lines every quotation needs
- Inverter: brand, exact model, continuous output, surge rating and hybrid/off-grid type.
- Battery: chemistry, nominal and usable kWh, voltage, BMS compatibility and warranty.
- Panels: quantity, watts per panel, total array size and string arrangement.
- Protection: DC/AC breakers, isolators, surge protection, earthing and correctly sized cable.
- Scope: mounting, transport, installation, commissioning and after-sales support.
A better way to request a 5kVA quote
List the appliances that may run together, their approximate watts and how many hours each should operate during an outage. Separate essential loads from optional heavy loads such as air conditioners, pumps, kettles and electric cookers. That lets the designer protect the budget without undersizing the system.
Do not compare two 5kVA quotations until the battery kWh, panel kW and installation scope are on the same page.
