Part of HIS connect® Solar Wiring System
HISbox® DC CombinerPower Plant
Your benefits:
- Optimized solutions, tailor-made to your plant requirements
- High level of safety through high quality, perfectly matched components
- Increase the plant cost effectiveness by heating tests carried out in our test laboratory
to check the best configurations during operation
Enclosures
High stability and reliability fitting for challenging project realisation. High impact resistance, high IP protection rating, door lock, integrated canopy, stainless steel mounting lugs with an integrated pressure equalisation element (prevents a build-up of condensation). UV and ozone stable, perfectly suited to outdoors.
Protection against lightning and voltage surge
Lightning and voltage surge arrestors for 2 pole isolated DC systems 1500V DC with remote signalling contact, temperature monitored protection elements and optical display for status monitoring fitted to the unit. Increase your plant security and reduce potential loss of productivity. Moreover, the replacement of components is very costly. Finally, with this, you will fulfil possible requirements of the financing banks, investors and insurance companies.
String protection
As well as the requirements of the product standard, the specific requirements of the plant must be taken into account. Both the protection of the linked system components and the use of the correct temperature coefficients must be taken into account. HIS has checked numerous configurations in its own test laboratory because a half job does not provide complete plant protection.
Isolators
DC isolators are designed for safe switching particularly when there are difficult switch off conditions in photovoltaic plants without affecting safety, efficiency and simplicity. The manually operated isolators are a cost-effective and reliable solution for the most diverse areas, especially where there are high ambient temperatures.
Power Supply
DC-DC converter, which has advantages such as high efficiency, high reliability and high safety isolation. This DC-DC converter provides a stable operating voltage for the load device. Its multiple protection features can enhance the safety performance of the module power supply and the load under abnormal working conditions.
Monitoring
Optimize your revenue by using high quality measurement technology. The identification of residual images is therefore enabled on string levels. On the one hand, this reduces the maintenance costs and at the same time, increases the operational reliability and cost effectiveness of your plant.
