Floating PV systems are perfect when it comes to finding new locations for PV plants despite today's scarcity of space. Water surfaces are particularly suitable for PV plants because of the low shading and the cooling effect of the water. However, the ambient conditions place high demands on the combiner boxes.
Our PV DC floating combiner boxes are designed for use in floating PV systems on freshwater surfaces more than 1 km from the sea and equipped with central inverters. They comply with IEC-61439 (Edition 2) and can withstand high humidity, a corrosive atmosphere and exposure to strong sunlight. We offer a wide range of plug&play variants with 8 to 24 inputs – along with comprehensive protection and appropriate covering solutions.

In floating photovoltaic plants, combiner boxes need to withstand the demanding conditions caused by high humidity and direct sunlight. Our combiner boxes for floating PV are the perfect solution for long-term efficiency.
Floating solar plants are on trend in the industry. However, if you're considering setting up a floating PV plant, you'll have a range of obstacles to overcome. On water surfaces in particular, it can be hard to maintain and service combiner boxes for PV plants. This results in high costs. When a solution fails, no power will be generated. This causes increasing electricity production costs (levelised costs of electricity/LCOE), and the entire investment in the floating PV plant can become unprofitable. As a project planner for large PV plants or a technical adviser, we're sure that you'll already be aware of these problems. Our combiner boxes for floating PV offer a range of advantages which allow you to counter the usual challenges.
Our combiner boxes for floating PV can be used even in environments with high humidity as per IEC-61439 Edition 2.
The combiner boxes for floating PV can be operated without additional shade, even in direct sunlight.
Our combiner boxes for floating PV have a PMMA cover to improve the reflection of sunlight and increase thermal performance.
The plug&play solution ensures the quick, easy and flexible installation of our combiner boxes for floating PV.
The high quality of our combiner boxes for floating PV has allowed us to increase the warranty term to 5 years.
Thanks to innovation and new ideas, our combiner boxes for floating PV are able to address typical concerns that arise in relation to floating PV systems. The special features of our products ensure that the combiner boxes for floating PV are able to withstand the harshest ambient conditions reliably and sustainably. Features include absorbing PMMA sun protection to protect the combiner boxes for floating PV from high temperatures and Multivia cable glands for optimum watertightness. Our products can meet all requirements.
PV floating DC combiner boxes are designed for harsh environments!
Thanks to the pre-mounted PMMA cover, our combiner boxes for floating PV do not require any additional preparation work before being installed. The innovative PV connection makes the entire solution plug&play-capable. Our combiner boxes for floating PV plants are made from GRP, which means that they do not need regular repainting. This is a decisive advantage over metal housings.
PV floating DC combiner boxes are specially designed for environments in Class B as per IEC 61439 (Edition 2) and 60058-2. This means that they are suitable for operation in extremely humid and corrosive environments. This means that they are suitable for operation in extremely humid and corrosive environments. This means that they are suitable for operation in extremely humid and corrosive environments.
PV floating DC combiner boxes can be operated in direct sunlight without the need to install an additional sun protection element. The pre-mounted PMMA cover also improves the performance of the system.
PV floating DC combiner boxes can be operated in floating PV plants on freshwater surfaces. They have been extensively tested and are certified for long-term operation in these specific environmental conditions.
Our combiner boxes for floating PV have already enjoyed success. In the Netherlands, Floating Solar BV has created three artificial islands with the largest and most dynamic floating solar farm in Europe. They plan to increase the number of islands to fifteen in the future. Due to the harsh environmental conditions and the long desired lifetime, the used combiner boxes for floating PV must also meet the most stringent of requirements. Our range has been tested and meets all electrical safety conditions. Find out more about the floating solar photovoltaic system in the Netherlands.

Our laboratory is accredited in accordance with international standards. It operates independently and is recognised by institutions, registration services, and other institutions and authorities. As a member of the CTDP program, Weidmüller is regularly audited by UL, especially regarding test methods, quality management and documentation.
PV DC combiner boxes are tested according to IEC-61439-2 and are constructed on the basis of the test results as well as assembled for the specific application. This ensures that each of the requirements of the target application is fully met.
The perfect complements to our combiner boxes for floating PV make your utility scale PV installations even more efficient. For example, our PV string monitoring systems can be used to collect and analyse data in order to allow you to precisely monitor your floating PV plants. Our PV AC combiner boxes are primarily designed for the requirements of large plants. They can be used to combine PV string inverters reliably and cost-effectively. Or you might like to benefit from our PV communication boxes, which you can use to connect up your floating PV plants with reliable and secure communication. More efficiency and productivity thanks to perfect complements for your floating PV plant.
