PV Systems are generally installed in scenarios where they can convert the largest amount of sunlight into electric power. However, it is not always possible to prevent dormer windows, chimneys, trees and other obstructions from casting shadows on PV modules. This reduces energy yield and lengthens a system owner’s payback period.
This is why SMA has developed a superior optimisation technique for every situation – SMA ShadeFix. And the best thing about this solution is that SMA ShadeFix optimisation is integrated into SMA inverters* at no extra cost.
Greater energy production
in most situations and over the entire lifetime of the system. Even in shading.
due to fewer components. This keeps the risk of failure to a minimum.
Improved quality & service life
thanks to field proven SMA products and automatic inverter monitoring.
through long-lasting solutions and high recyclability.
More reliability due to fewer components.
Why do we use integrated solutions at SMA? Because as the number of components in the entire system increases, so does the failure rate of the PV system. This is why you should never install more devices than necessary.
The benefits are clear:
- Less work involved in installation and planning
- No additional electronics on the roof
- No unnecessary risk of fires and accidents
- Faster service thanks to SMA Smart Connected
Highly sustainable due to first-class complete solutions
There are, of course, many more reasons for an efficient system design: effective material use, low transportation costs, fewer service calls required – these are only a few examples. As an innovative company, we are always thinking one step ahead in order to combine long-term business success with environmental protection and social responsibility.
- High material efficiency and durable products
- High recyclability as fewer components are used
- CO2 savings thanks to the efficient solution

Why and How SMA ShadeFix achieves the highest energy production
For all PV installers or solar system owners, our whitepaper unveils the results of the results of a study conducted by the University of Southern Denmark that compares SMA’s advanced PV optimisation technology relative to other forms of optimisation under a variety of unshaded and shaded conditions.
You’ll read key findings about:
Lifetime energy harvest
Reliability and maintenance
Fire and installer safety
Safety and code compliance in Europe and US
Here you can find answers to frequently asked questions
SMA ShadeFix is our software-based shade management system. Commonly this feature is used in systems with light to medium shading. Your energy yield is optimised without adding any further components to the system or PV modules. SMA ShadeFix is already integrated into SMA SUNNY BOY and SUNNY TRIPOWER inverters and activated automatically during commissioning. There are no additional costs because SMA ShadeFix is an integral part of the operation management of SMA SUNNY BOY and SUNNY TRIPOWER inverters.
SMA ShadeFix uses an intelligent and proven MPP tracking system for many years to determine the operating point with the highest output during shading conditions. With SMA ShadeFix, SMA solar inverters use the best possible energy supply from the PV modules at all times to increase yield in shaded systems.
SMA ShadeFix optimises the energy yield in systems during standard shading conditions. This makes SMA ShadeFix the ideal solution in most shading situations to make the best use of the available power of the PV modules. SMA ShadeFix is a software-based solution and is already integrated into SMA SUNNY BOY and SUNNY TRIPOWER inverters. As with conventional power optimisers, additional installation efforts are not required. The advantage of this is a minimised risk of failure of the entire system. The costs for system planning and assembly are kept low. SMA ShadeFix is an integral part of the inverter operation management, included in the acquired scope of services of SMA SUNNY BOY and SUNNY TRIPOWER inverters. Further acquisition costs, as with other power optimisers, are no longer necessary and the amortisation period of the system is not unnecessarily extended.
SMA ShadeFix is based on shade management system OptiTrac Global Peak. In the future, SMA will place an even stronger focus on this feature and the ongoing technical development of this solution for shade management. For this reason, we have decided to reposition the feature in the market and give it the attention it deserves.
SMA ShadeFix is available in SMA SUNNY BOY and SUNNY TRIPOWER inverters (see inverter manual or technical datasheet). The parameter name may not yet be shown in the user interface. However, the feature is fully available since SMA ShadeFix is activated by default.
From September 2019, all updatable SMA solar inverters with OptiTrac Global Peak will successively receive a firmware update The feature is updated automatically. The status of the feature remains the same and no further settings are required.
The feature is activated by default in current SMA solar inverters If necessary, the time interval at which the inverter determines the optimum operating point can be adjusted via the user interface (see inverter manual). No further settings are necessary.
A superior model for power optimisation.
