The Archai System combines power optimisers, a data gateway, and the SolarSync monitoring platform - engineered to improve solar system safety, efficiency, and visibility.


Archai Power is a UK-led solar technology company designing and managing optimisation systems for safer, more efficient solar installations.
Our systems are manufactured in South Korea under strict quality control, ensuring long-term reliability for installers, EPCs, and distributors.

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.

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

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

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

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.
