- Highly flexible – for decentralized or centralized plant designs
Highly flexible – for decentralized or centralized plant designs
No matter, whether you would like to use the REFUsol 100K in decentralized or centralized plant designs, it is a perfect fit for both variants. The roomy ConnectionBox is available with either fused direct string connections for distributed designs, or with a single DC input for centralized designs.
Installation just in time – for maximized ROI
The ConnectionBox and Inverter can be delivered independently in separate shipments: in effect, the ConnectionBox is installed during cable work, the power conversion unit (inverter) just before commissioning. Hereby costs are optimized and risks reduced.
Always compatible – worldwide
The REFUsol 100K can be connected to any grid voltage between 380 and 480 VAC, offering maximum power between 83 and 100 kVA.
REFUcube
No either / or decision.
Key features of REFUcube
- Reduced costs and risk
- Easy installation thanks to plug & play preparation
- Reduced maintenance
- Available in power classes – from 0.5 MW to 3 MW
Reduced maintenance
Thanks to the natural convection cooling of the REFUsol 46K inverters and the intelligent ventilation concept of the container don’t require fans or air conditioning for the inverter compartment. This means the need for maintenance is kept to a minimum.
Ease and celerity of installation
The REFUcube comes already as pre-wired container, internally all DC cables, AC wiring and distribution as well as data communication are already installed. It can be transported easily to and handled at the solar plant location thanks to its low weight and compact design. The REFU CombinerBoxes are positioned close to the solar panels and therefore allow short PV string cables and only one cable pair (+/–) from each DC CombinerBox to the container.
Risk reduction
The REFUcube ensures an optimal compatibility of all components in the system and is conceptualized as a plug & play solution. The integration of string inverters allows on the one hand an easy replacement in case of problems, while on the other hand guaranteeing a continuous operation of the remaining inverters. Therefore the overall system availability will be close to 100 %.
Cost savings
The design and easy installation of the REFUcube provides several areas of cost savings: the reduction of cabling, minimized set-up and installation effort as well as reduction of commissioning costs.
