Residential Solar PV with Archai Optimisers

Project Details

System Design

System Size: 7.2 kWp (2 x 3kW Solis inverters)
Panel Types: JA Solar Bi-facial 450W & DAS N-Type 450W
Mounting System: K2 Dome 6
Optimisation: Archai Power optimisers fitted on shaded strings to maximise yield
Expected Annual Yield: 5,188 kWh

Technical Setup

Compliance: Fully certified under BS7671 (IET Wiring Regulations) and Building Regulations 2010
DNO Approval: Connection approved under ENA G99 Type A by Electricity North West (ENWL)
Isolation & Protection: Lockable AC/DC isolators installed for safe operation and maintenance
Monitoring: PV generation meters fitted for both inverters, enabling precise performance tracking
Certification: Full NICEIC and MCS certification issued on completion

This robust design ensured the system met regulatory requirements while giving the homeowner confidence in safety and long-term reliability.

Results & Impact

Shading Mitigation
By installing optimisers, mismatch losses from shaded panels were eliminated. Each panel could operate independently, preventing underperformance across the array.

Performance Gains
Post-installation testing confirmed a consistent 10–15% uplift on shaded strings compared with baseline performance, securing more energy for the homeowner throughout the year.

Reliability
Commissioning tests confirmed seamless integration with the DNO network. The system was proven to operate in parallel with grid supply without disturbance.

Safety & Compliance
All commissioning checks were passed, including isolation, synchronisation, and protection settings. Certificates included:

G99 Commissioning Certificate – signed off by ENWL and the installer
NICEIC Compliance Certificate – ensuring electrical standards compliance
PV Handover Certificate – detailed inverter serials, panel test results, and measured parameters
As-Built Schematic – clear layout of system design, isolation points, and consumer unit connection

Industry Recognition
This installation formed part of Archai Power’s Official Solis Certification process, strengthening confidence in both the optimisers and the SolarSync monitoring platform as reliable, scalable solutions.

Conclusion

This Stockport installation shows how Archai optimisers unlock additional generation potential even on partially shaded rooftops — a common challenge in UK residential projects. By delivering higher yield, full compliance, and long-term safety, the system ensures the homeowner benefits from maximum return on investment, peace of mind, and future-ready integration with the grid.
