Yield optimisation directly from the inverter

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.

Improved quality & service life
thanks to field proven SMA products and automatic inverter monitoring.

Greater sustainability with SMA ShadeFix

Greater sustainability
through long-lasting solutions and high recyclability.

SMA ShadeFix produces more power than alternatives

SMA ShadeFix is a software solution integrated into the inverter that comprehensively optimises energy yield in PV systems and in most cases is more effective than module optimisation hardware solutions.  This was proven by a scientific study entitled “The Impact of Optimisers for PV Modules” carried out by the University of Southern Denmark in May 2019.

SMA ShadeFix optimiser - No shading

No shading
The ideal PV system is not shaded and achieves maximum energy production with SMA ShadeFix optimisation. Why? Lower conversion losses and electricity demand of the module optimisers.

SMA ShadeFix optimiser - Light shading

Light shading
Sometimes a chimney or roof vent causes mild shading. SMA ShadeFix optimisation achieves greater energy production than traditional module optimisers in these situations, too. How? Optimisers require additional power to operate, sapping system production.

SMA ShadeFix optimiser - Medium shading

Medium shading
Moderate shading may occur from nearby trees but even that is no match for ShadeFix optimisation. SMA’s cutting-edge technology still outperforms traditional optimisers by finding the optimal operating point without consuming unnecessary power or adding superfluous hardware to the system.

SMA ShadeFix optimiser - Heavy shading

Heavy shading
Traditional module optimisers only yield additional energy gains vs ShadeFix optimisation in heavily shaded systems. A system design with selective deployment of module optimisers can be useful here.

SMA ShadeFix
Fewer components, enhanced safety and a longer service life. Maximum sustainability.

How SMA ShadeFix works

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.
