Battery systems are comprised of multiple individual cells combined in strings to achieve a specific aggregated voltage output, whilst the active area (cross section) of the battery determines the energy storage (amp-hrs) capability. Battery solution providers constantly find themselves balancing the inherent pros and cons between the number and size of cells for a specific application.

Where the greatest historic tension has risen is between the inverter preference for high dc-voltage so it can achieve high conversion efficiency (requiring a large number of individual battery cells) and the battery desire for a few large cells so it will be cost effective, long-lived, reliable and easy to site/maintain.

Marathon LR offers a breakthrough in this paradigm by efficiently and effectively providing a bridge between the battery and inverter technologies allowing providers to source a smaller quantity of high amp-hr batteries and still take advantage of high efficiency inverters.
