Want to run fans, lights, TV and a laptop overnight without a generator. Realistic budget?

Rough installed prices seen in Lagos and Abuja quotes in 2025:

A 1.5 to 2.5 kVA inverter with a 2.5 to 5 kWh lithium battery and four to eight panels: 1.2 million to 3 million naira.
Lead-acid batteries are cheaper up front but last two to three years instead of seven to ten.
Air conditioning needs a much bigger system; budget from 4 million and upwards.

Get at least three written quotes that name the inverter brand, the battery cell type and the panel wattage, and ask for the warranty in writing. Fake lithium batteries with fewer cells than claimed are a common complaint. Add a change-over switch so NEPA and solar do not clash.
