The server rack cabinet was used for 6 x 3.5Kw battery packs for my solar PV system. The installers who originally installed the system had just stacked them one on top of the other with no air gap between creating a real risk of overheating and fire. The new rack now has them installed with an inch/25mm space between for air flow. A much safer and visually impressive configuration. There is also space for further Battery modules to expand the energy storage. Ordering and delivery went smoothly and the rack arrived about half-an-hour before the engineers arrived to do the reconfiguration. Brilliant!
