Sungrow Solar Panel Optimisers


Sungrow’s solar optimisers are engineered to deliver high-efficiency output, enhanced safety, and long-term reliability — backed by one of the most trusted names in global solar technology. 
Designed for both residential and commercial PV systems, these optimisers help installers tackle challenges like shading, complex roof layouts, and retrofitting older arrays. Sungrow delivers the flexibility, reliability, and results installers need.

Sungrow optimisers are designed to work seamlessly with Sungrow inverters, forming a fully integrated solution that’s easy to design, scale, and install. The system supports advanced features like module-level monitoring, rapid shutdown, and intelligent fault detection—giving installers the tools they need to deliver safer, more efficient PV systems.

  • Increased Power Generation and Efficiency: Using Shade-Proof technology, Sungrow solar optimisers can increase system output by up to 30% in conditions where shading, mismatch, or multi-orientation layouts affect performance. Each module operates independently at its maximum power point, unlocking more usable energy, especially on UK rooftops where ideal conditions are rare.
  • Maximum Power Point Tracking (MPPT) at Module Level: Sungrow optimisers perform real-time MPPT on each individual panel, ensuring optimal energy harvest across your array. This technology can increase total system yield by up to 25% in installations affected by shading, orientation mismatch, or uneven module performance.
  • Safe and Reliable: Sungrow’s optimisers meet global safety standards, including NEC 2017/2020, for module-level rapid shutdown. This ensures enhanced safety for firefighters, maintenance teams, and emergency responders - a growing priority in commercial and hybrid solar systems.
  • Improved Safety: Sungrow optimisers feature rapid shutdown to 30V within 20 seconds, ensuring safety during maintenance and emergencies. They also have IP68 waterproofing and C5 anti-corrosion protection, ensuring reliable long-term performance in tough UK conditions — including coastal, industrial, and high-moisture environments.
  • Plug-and-Play Installation: Sungrow optimisers are designed with a plug-and-play structure for fast, error-free installation. They integrate seamlessly with Sungrow inverters and monitoring systems, reducing setup time and improving commissioning efficiency. Their flexible design suits a wide range of roof types, including multiple tilt angles and orientations, making them ideal for complex UK rooftops and commercial-scale installations.
  • Smart Monitoring & Diagnostics: Sungrow optimisers work seamlessly with iSolarCloud, enabling real-time, module-level performance tracking. Installers receive instant alerts for shading, faults, or performance issues, helping reduce O&M costs and ensuring systems run at peak efficiency.

Sungrow solar optimisers offer high-performance, scalable optimisation for UK installs of all sizes — from shaded residential roofs to commercial and utility-scale systems. They boost energy yield, enable advanced monitoring, and support safer, more efficient installations, making them ideal for both new projects and retrofits.

As an authorised UK distributor, we help professional installers source the latest Sungrow solar optimisers at competitive trade pricing. All units come with full manufacturer warranties and detailed technical datasheets to ensure accurate system design and easier installation.
