Optimised Inverters


Optimised inverters, when used with DC power optimisers, create a hybrid solar solution that combines the advantages of traditional string inverters and microinverters. Each optimiser is attached directly to a solar panel, enabling module-level Maximum Power Point Tracking (MPPT) and real-time performance monitoring. This allows every panel to operate independently, reducing the impact of shading, soiling, or panel mismatch on total system output—helping to maximise energy efficiency.

The optimised DC power from each panel is delivered to a central inverter, which converts it into usable AC electricity for homes or businesses. This consistent voltage input improves inverter efficiency, unlike traditional string inverters that must cope with fluctuating voltages.

These systems also offer advanced safety features, including rapid shutdown capability, which provides panel-level shutdown to support fire safety and meet UK compliance requirements. With internet connectivity, they support proactive maintenance—automatically notifying installers of any faults, allowing fast, remote diagnostics and timely resolution.
