17 kW Dual-Zone Hybrid Solar Installation – Zamfara

Two Independent FIRMAN Hybrid Systems • 17 kW Combined Inverter Capacity • 16.74 kWp JinkoSolar PV • 20 kWh Felicity Battery Storage

This office solar installation in Zamfara was engineered as two independent hybrid power systems, each dedicated to a separate section of the office building. The design provides clear load segregation, independent operation and improved fault isolation across the facility.

System 1 – Office Zone A

• Hybrid Inverter: 1 × FIRMAN FH6K011 6 kW Smart Hybrid Inverter
• Solar PV: 9 × JinkoSolar 620 W modules — 5.58 kWp installed PV capacity
• Battery Storage: 1 × Felicity Solar 10 kWh lithium battery
• Application: Dedicated supply to one section of the office building

System 2 – Office Zone B

• Hybrid Inverter: 1 × FIRMAN FH11K0110 11 kW Hybrid Inverter
• Solar PV: 18 × JinkoSolar 620 W modules — 11.16 kWp installed PV capacity
• Battery Storage: 1 × Felicity Solar 10 kWh lithium battery
• Application: Dedicated supply to a separate section of the office building

Overall Installed Capacity

• Total Inverter Capacity: 17 kW across two independent hybrid systems
• Total Solar PV: 27 × 620 W JinkoSolar modules — 16.74 kWp
• Total Battery Storage: 20 kWh nominal lithium storage
• Protection: Complete required AC and DC protection installed and intact for both systems
• Scope: PV installation, inverter and battery integration, load segregation, electrical protection, system configuration, testing and commissioning

Engineering Approach

The two inverter systems were deliberately configured to operate independently rather than in parallel. Each system has its own PV array and battery bank and supplies a different section of the office building. This architecture simplifies load management, reduces interdependence between office zones and allows one section to remain operational independently of the other.

Project Outcome

The completed installation provides the office with 17 kW of combined hybrid inverter capacity, 16.74 kWp of solar generation and 20 kWh of lithium battery storage, distributed across two independently operated power zones with complete electrical protection.
