One Connected System for Safer, Smarter Solar

The Archai System combines three key elements - the optimiser, the data gateway, and the SolarSync monitoring platform. These components work together to deliver consistent energy generation, faster fault detection, and enhanced safety at every panel.

Panel-Level Control with Maximum Power Point Tracking

Each solar panel operates independently, continuously adjusting to deliver its best possible power output under real conditions.

Built-In Rapid Shutdown Safety

In the event of maintenance or an emergency, the system can safely reduce voltage at the panel level within seconds, protecting people and property.

Power Line Communication

The optimisers send data through existing electrical cabling, avoiding the reliability issues that can occur with wireless systems.

Scalable System Design

One Data Gateway can manage up to 30 optimisers, making the system suitable for small residential rooftops and large commercial arrays.

The Risks of a Non-Optimised System

With Optimisers

Without Optimisers

Panel-level control and safety isolation
High voltage runs through full array
Consistent output even with shading or dirt
One shaded panel can lower output for all
Faultsvisible via monitoring platform
No visibility of underperforming panels
Faster, targeted maintenance
Manual inspection and testing
Higher energy yield and better ROI
Energy losses accumulate over time

Proven in the field - Case Studies

In a recent projects, Archai optimisers have delivered a 10–15% improvement in energy generation on shaded arrays, meeting full UK compliance standards under BS7671 and ENA G99.

Residential Solar PV with Archai Optimisers

A homeowner in Stockport wanted to cut energy bills, improve independence from the grid, and ensure their solar system performed at maximum efficiency. The chosen setup combined 16 high-efficiency 450W panels, two Solis 3kW inverters, and Archai Power optimisers fitted on shaded strings to overcome roof layout challenges. The result was a 7.2 kWp system that not only met all UK compliance requirements but also achieved a 10–15% uplift in generation on shaded arrays.
