10kVA Hybrid Solar Inverter & Rooftop PV Gwarinpa, Abuja
The estate brief was clear: “Less noise, fewer fuel runs, and stable power for pumps and appliances.” We started with a load audit, logging peak demand, pump start currents, and typical evening consumption. The roof survey identified two usable faces; we modelled panel placement to avoid self-shading and left clear walk paths for future cleaning.
Our design paired a 10kVA hybrid inverter with a larger PV array for strong daytime self-consumption and reliable battery charging. We sized lithium storage for 8–10 hours of mixed-load backup and added energy monitoring so the homeowner could see “where the power goes” in real time. The proposal outlined scope, timelines, and warranties; once approved, we staged deliveries to minimize disruption inside the home.

Services: Survey, Engineering Design, PV & Battery Installation, Hybrid Inverter Setup, Monitoring & Scheduled Maintenance
Installation took three days. Day one: mounting structure, panel placement, DC cabling, and weather-sealed penetrations. Day two: inverter and battery wall, AC protection boards, and surge/earthing upgrades in line with best practice. Day three: tidy-up, labelling, and thorough testing—string voltages, breaker function, safe disconnection, and controlled load ramp-up to confirm stability during switchover.
We configured smart settings—prioritizing solar during the day, enabling quiet battery operation for evenings, and reserving a small battery buffer to ride through late-night blips. The handover session covered the app/dashboard, simple maintenance (panel rinsing schedule, keeping vents clear), and who to call if anything looks unusual.
Post-installation, the estate reported dramatically fewer generator hours, cooler and quieter nights, and better appliance protection thanks to stable voltage. We scheduled quarterly remote checks and left a short maintenance checklist with the facility team.
