10kW Solar Energy Solution – Idimu, Lagos State (July 2025)
In July 2025, we deployed a 10kW SRNE hybrid inverter paired with one SRNE 16kWh lithium battery and 20 units of 550W JA Solar bifacial panels for a 4-bedroom apartment in Idimu, Lagos State. The system delivers stable and efficient power for all lighting points, freezers, three fans, two air conditioners, a refrigerator, and other critical appliances.

- Reliable energy storage for day and night use
Reduced reliance on grid power and generators
Lithium battery bank installed to provide reliable backup during outages and nighttime hours
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.

Results & Impact
Production stability: Sequenced starts and voltage regulation reduce brownouts and stoppages.
Fuel/OPEX drop: ~50–65% reduction in generator runtime and associated costs.
Equipment protection: AVR layer and surge protection safeguard control electronics.
Workplace efficiency: Smoother restarts after grid events; better shift transitions.
Estimated solar yield: ~144–180 kWh/day (seasonal).
CO₂ avoided: ~12 t/year (indicative).
Operator empowerment: Supervisors trained on dashboards and simple response playbooks.
Service plan: Quarterly PM (thermal scans, torque checks, cleaning, firmware updates).
