Products for ground-mounted photovoltaic systems

Find out about our impressive product highlights. We face your challenges with the perfect combination of innovation and experience. This means that you can rest assured that our range of products for pv parks will meet all of your requirements. Our solutions allow you to operate your plants efficiently with low electricity production costs (levelised cost of electricity/LCOE). With our PV string monitoring system, you can keep an eye on your plant, and our various combiner boxes meet the requirements placed upon them by the most diverse of usage environments. Our products allow you to create utility scale PV plants that precisely meet your needs!

PV DC combiner box

Our PV DC combiner box can be used to efficiently bundle, protect and combine central inverters in PV farms.

PV DC combiner boxes for high-power panels

Our PV DC combiner boxes enable easy connection in PV plants with monofacial and bifacial modules or half-cell modules. The used circuit breakers enable a higher current consumption.

PV retrofit combiner boxes

The installation of our PV retrofit combiner boxes makes it possible to obtain data at string level in PV systems with existing, unmonitored PV-DC generator combiner boxes.

PV floating DC combiner box

Our innovative combiner boxes for floating PV systems combine, protect and monitor DC strings in extreme environmental conditions. We have the perfect solution for your floating plants.

PV AC combiner box

Our PV AC combiner box allows PV string inverters in large PV plants to be combined reliably and cost-effectively.

PV communication boxes

Connect individual power plants of your utility scale photovoltaic system using reliable and secure industrial communication with one of our PV communication boxes.

PV string monitoring system

Our new PV string monitoring system is integrated into the DC combiner boxes of utility scale photovoltaic plants with central inverters. It was developed to monitor the current and voltage of individual strings and to determine the SPD and breaker status in the combiner box of PV plants.

PV weather boxes

Reliable information on all important weather parameters: Temperature, irradiance, wind speed and direction, precipitation, relative humidity, and much more can be permanently recorded.

The perfect solution for every concept

Whatever the concept is for your ground-mounted photovoltaics, we have the ideal solution. Looking for a compact, cost-optimised solution for creating or optimising your central inverter PV plant? Our high-quality DC combiner boxes are the answer. Or perhaps you want to equip your string inverter PV plants with AC combiner boxes that provide reliable, robust protection against voltage surges and short circuits. Our range includes this product, too. And there's more: Our string inverters are really easy to separate from the system when you need to perform thorough maintenance. Inverters, half-cut cell technology and solutions for bifacial modules – our product range can meet all requirements.

Reference projects

Our past projects show that our large-scale photovoltaics products are really successful in the real world. For example, we've already been able to participate in the installation of a floating solar photovoltaic plant in the Netherlands. Our solutions for floating PV projects have been tested and meet all electronic safety requirements. This helps to ensure that the PV farm will withstand harsh ambient conditions and achieve the long desired lifetime. Because the project has been so successful already, it is planned to increase the number of islands in the future.

Our satisfied customers are the best proof of the quality of our solutions. Here you will find examples of successfully implemented projects.
