Tigo TS4-A-O 700W – Smart anti-shading solar optimiser
Maximize energy production from your solar panels with Tigo TS4-A-O: flexible optimization, module monitoring, NEC compliance.
Optimise Your Solar Power Output with Tigo TS4-A-O: Performance and Savings
Discover how the Tigo TS4-A-O is revolutionising the optimisation of your solar installations. This innovative solution offers unrivalled flexibility and targeted optimisation, ensuring maximum energy output whilst reducing costs.
Key Features
Flexible and Targeted Optimisation
Every solar installation is unique. With the Tigo TS4-A-O, you can equip only those panels that require optimisation, thereby saving on costs. Ideal for partially shaded installations or those with complex configurations.
How It Works
Power optimisers are installed on each panel to maximise the output of each panel by controlling the direct current before it reaches the central inverter.
Scenarios to Avoid
- In installations where all panels are uniformly oriented and exposed, power optimisers may not offer any significant benefit.
- For simple installations without shading or varying exposure conditions, the benefits of optimisers may be minimal.
Typical User Profile
- Users with installations where panels may be partially shaded or where sunlight exposure conditions vary.
- Installations with panels oriented differently or at varying angles.
Key Benefits
- Module-level monitoring
- Rapid shutdown compliant with NEC 2014, 2017 and 2020 standards
- Production optimisation: Improves panel efficiency by optimising output at the panel level, even if some panels are shaded.
- Lower Cost: Less expensive than micro-inverters as the central inverter is still used for DC/AC conversion.
- Less Frequent Maintenance: The centralised inverter reduces the need for on-roof maintenance.

Configuration and Installation
Easy and Flexible Configuration
The Tigo TS4-A-O is designed for use with one module (panel) per unit. This allows for flexible installation tailored to the specific requirements of your photovoltaic system.
Detailed Product Description
Description
Optimisation is a Flex MLPE feature available as an add-on unit (TS4-A-O). Design your system using unequal string lengths, mixed orientations or mismatched areas. Install in shaded areas with a reduced derating ratio. In addition to optimisation, the TS4-A-O enables module-level monitoring and rapid shutdown in accordance with NEC 2014, 2017 and 2020 standards.
Applications and Uses
The Tigo TS4-A-O is ideal for a variety of installations, including residential, commercial and industrial systems. Whether your installation is partially shaded or features complex configurations, this device ensures optimal performance.

CURRENT DC OPTIMISERS

- All solar panels must be fitted with an optimiser, whether or not it is necessary
- Quickly leads to high, unnecessary costs
THE SMA AND TIGO SOLUTION

- Only the panels affected (e.g. by partial shading) need to be fitted with an optimiser
- Reduced investment costs
- Lower installation costs
Why install a Tigo TS4-A-O solar optimiser?
In a conventional photovoltaic system, solar panels are usually connected in series. When a single panel is affected by shading, dirt build-up or a drop in performance, the output of the entire string can be reduced.
The Tigo TS4-A-O solar optimiser allows the affected panels to be optimised individually, thereby minimising production losses and improving the system’s overall efficiency.
- Reducing losses caused by partial shading
- Panel-by-panel optimisation
- Compatible with most string inverters
- Individual monitoring of photovoltaic modules
- Safety function and rapid shutdown (depending on configuration)
- 25-year manufacturer’s warranty
Who is this product recommended for?
The Tigo TS4-A-O is particularly suitable in the following situations:
- Where trees cast shadows on the roof.
- A chimney, aerial or other obstacle creating shaded areas.
- Panels facing different directions (south, east, west).
- Differences in performance between certain modules.
- Projects to renovate or upgrade an existing installation.
- Need to monitor panel output individually.
Practical example of use
A 12-panel photovoltaic installation has a chimney that casts a shadow over three panels in the late afternoon. Without optimisation, the output of the entire string may be affected.
By installing Tigo TS4-A-O optimisers only on the affected panels, losses are minimised and the system’s overall efficiency is improved whilst keeping costs under control.
