Power Optimisers
Our range of high-performance solar panel optimisers for commercial and residential installations across the UK features advanced solutions from leading manufacturers, including Sungrow. The power optimisers are designed to maximise energy yield, enhance system flexibility, and reduce performance losses caused by shading or solar panel mismatch.
A solar optimiser - also known as a power optimiser for solar panels - is a module-level power electronic (MLPE) device that sits between traditional string inverters and microinverters. Attached to each panel, these DC-DC converters perform maximum power point tracking (MPPT) at the module level and convert its optimal DC output to match system-wide performance. This allows each panel to operate independently while still feeding into a single central solar inverter, maximising energy harvest even in systems affected by shading, roof angle variation, or debris, and helping to reduce performance degradation and maintain long-term efficiency.
- Enhanced energy yield: Each PV panel optimiser independently maximises its module’s output even under shading or uneven conditions.
- Design flexibility: Accommodates uneven rooftops, multiple orientations, or partially shaded arrays. Optimisers allow for more flexible design and installation of photovoltaic systems.
- Rapid shutdown compliance: Meets safety standards for maintenance and emergency situations. By reducing the risk of underperformance or damage, optimisers contribute to the safety of solar installations.
- Real-time monitoring: Panel-level data enables real-time performance insights, fault detection, and proactive maintenance.
- Improved long-term performance: Reduces losses from shading, mismatch, and dirt accumulation. By preventing underperformance or damage to individual panels, optimisers contribute to the overall longevity of the PV system.
- Compatible with Central Inverters: Allows module-level optimisation while using a single solar inverter—balancing performance with cost efficiency.
As an authorised UK distributor, Alternergy supplies high-quality solar DC optimisers from Sungrow and Sungo. They are fully compatible with their respective inverter and monitoring platforms, ensuring seamless system integration and maximum energy efficiency.
