50kVA Solar Inverter & Rooftop PV Manufacturing Workshop, Ibadan
For the workshop, the pain points were production stoppages and equipment stress from voltage dips. We began with an industrial audit: logging machine start currents, compressor cycles, and office IT loads over a typical week. We identified circuits to prioritize during outages and proposed sequencing high-inrush loads to avoid nuisance trips.
Our 50kVA 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.

On the roof, we built robust sub-arrays with correct spacing for heat dissipation and access. DC cabling was run in UV-stable trunking with safe drip loops, and all junctions were labelled. Inside, we installed the inverter, battery stacks, protection panels, and a dedicated maintenance clearance zone. We reworked earthing to reduce impedance and implemented surge protection at strategic points in the system.
Commissioning involved line-by-line checks: DC strings, AC boards, breaker discrimination, and staged load tests. We also programmed delayed starts for the biggest machines so the system could ramp without stress. Supervisors received training on the monitoring dashboard and a simple “what-to-do” guide for shift leads.
Results were immediate: fewer brownouts, smoother machine starts, and a noticeable reduction in fuel runs. The client enrolled in quarterly preventive maintenance—thermal scans on boards, torque checks on terminals, firmware updates, and dust management for panels and power rooms—protecting output over the long term.
