1stess 6200W Solar Inverter Project Case
Residential solar backup for a home and office in Lagos
Client and project background
Daniel Okoro is a homeowner and building services consultant in Lekki, Lagos. He uses a dedicated home office for technical drawings, online meetings and project administration while sharing the property with his family. He wants a defined backup circuit, documented operating settings and a clear local service process.

1stess 6200W Solar Inverter for a Lagos Home and Office
A home office needs a clearly defined backup circuit when the same building also supplies everyday household appliances. This illustrative Lagos project shows how a 1stess 6200W 48V hybrid solar inverter can support that requirement through load separation, battery integration and a documented handover.
A customer with practical service requirements
Daniel Okoro, a homeowner and building services consultant in Lekki, works from a dedicated office and lives at the property with his family. In this scenario, interruptions to the incoming supply affect his workday. His priorities are lighting, internet access, computer equipment and selected household loads. He asks the local installation contractor for an understandable circuit schedule and a system that can be maintained without guessing how it was configured.
A defined system and a realistic load boundary
The example configuration pairs one 1stess EM6200T-48L with a 6.0kWp solar array and two 51.2V 100Ah LiFePO4 modules in parallel, providing 10.24kWh of nominal storage. Battery operating voltage, combined discharge capability and communication compatibility require confirmation for the selected modules. Nominal capacity does not specify usable energy or guaranteed backup hours.
The inverter provides pure sine wave output, a 48V battery platform and MPPT solar charging up to 120A. The contractor assigns the essential circuit to the main output and a separately identified discretionary circuit to the second output, checking operating behavior against the final manual and firmware. Both outputs share the inverter's 6.2kW total rating. High-demand appliances remain outside the essential backup circuit.
Commissioning and handover as part of delivery
Installation is complete before the project enters routine use. The commissioning record covers protective devices, earthing, cable identification, PV and battery checks, charge settings and output tests. The installer checks equipment transfer behavior and assesses any requirement for a separate UPS.
Daniel receives a circuit list, approved settings, a shutdown procedure and service contact details. A follow-up visit reviews ventilation, accessible connections, alarm history and the family's use of discretionary appliances. These records give the next technician a clear starting point for service.
Project value for installers and buyers
The project is presented at the operation and maintenance stage, with a defined backup scope, labelled distribution and an accessible service layout. These details help installers, importers and procurement teams evaluate the application. Savings, runtime and availability require evidence from a real installation before publication as results.
