What the project is
NEW – DISCOVER OUR NEX RS SOLAR BOILERS. The NEX RS series (https://www.nexol-ag.net/nex-rs) represents more than just solar electricity – it creates warmth and comfort sponsored by the sun! This project introduces photovoltaic water heating through smart, retrofittable heating elements that work directly with electricity from photovoltaic modules. In essence, these heating elements can be easily installed into existing systems, delivering renewable and sustainable energy that reduces energy costs while keeping water hot and ready.
Main Benefit
Key figures and facts include:
- SIMPLE INSTALLATION: Direct use of DC electricity from PV module.
- RELIABILITY: High quality components offer dependable hot water on or off the grid.
- INTELLIGENT: Heats the top of the storage first to deliver continuously shower-ready water.
- FLEXIBLE USE: Works with both DC and AC electricity and autonomously decides which source to use – solar is always preferred!
Design and Functionality
The NEX-R series products are designed with a plug-play approach that simplifies installation. As soon as the sun begins to shine, voltage builds up in the solar modules and flows from the series-connected solar modules to the Nexol Energy Controller. There, the voltage passes through the DC/DC converter with virtually no loss before reaching the DC coil of the AC/DC screw-in heater. Depending on the performance of the modules, the screw-in heater immediately begins to convert all available energy into heat, quickly warming the storage tank. This straightforward yet innovative process allows anyone with a bit of technical skill to install a renewable energy solution, making it an ideal addition to pre-existing systems.
Installation and Retrofitting Capabilities
The plug-and-play design provides a flexible solution for retrofitting existing heating systems. These smart elements can control one or two heating elements and heat the storage tank in layers, significantly shortening the heating time and increasing comfort for the end customer. This installation method is not only simple but also builds on the idea that renewable energy should be accessible and efficient. The design allows a skilled end customer to carry out the installation, merging modern convenience with sustainable practices as easily as flipping a switch.
Advanced Energy Control
At the core of the project is the Nexol Energy Controller, which intelligently governs the energy dynamics for reliable performance. When the sun is out, voltage is collected from the solar modules and efficiently converted to heat. And when the weather turns cloudy or the sun goes behind the clouds, mains power serves as a backup for reheating the water without any risk of overheating. The system’s design prevents overheating through the natural regulation provided by the solar modules, so even winter frost is no problem. This robust energy management technology highlights the commitment to safety, efficiency, and environmental friendliness.
