3.3kW / 4.995kWp Solar Inverter Installation – Lekki, Lagos State (november 2025)
Bravestone Energy Solutions installed a 3.3kW / 4.995kWp solar power system for a frozen food outlet in Lekki, Lagos State. The system powers all lighting points and three deep freezers, ensuring uninterrupted operation for the business.
Our 3.3kw design included ample PV for daytime offset, lithium storage to smooth transitions and cover shift changes, and an AVR layer to keep sensitive control electronics within safe voltage bands. We produced a clear method statement and safety plan, then coordinated installation hours around production so the factory stayed productive.
