This domestic client had a 5 kVA hybrid solar powered system with 8 x 105Ah lead acid batteries, which lost their capacity long before anticipated. After conducting a thorough research and learning about the benefits of Sirius supercapacitor storage, the client found that the Sirius supercapacitor energy storage modules would be the ideal solution for their needs. So, their previously installed system was replaced with Sirius supercapacitor storage. After only a month of installing the initial system, the client was so impressed with the performance that he placed another order to expand the new system. He and his wife now enjoy the gratification of having their security system up and running even during a blackout.
