For more than 15 years, GWL a.s. has been testing, researching and supplying only the highest quality LFP battery cells. Under the Amvolt brand, GWL has developed complete battery storage system in a wide range of sizes and applications. Available as final products or as production blueprints for localized assembly anywhere in the world.
The main principle of the Amvolt battery storage concept is technical openness. We try to free our customers from vendor lock-in, i.e. dependence on a specific supplier. Our battery packs are most often used for energy storage to reduce electricity consumption from the grid and increase self-consumption obtained, for example, from solar energy. It is therefore a solution to increase the level of self-sufficiency and independence from the grid.
Customers of Amvolt Battery Packs are mainly installers of solar power plants with the storage (from single-family homes to large industrial sites and everything in between) who are looking for an alternative to often unavailable or poor quality closed battery storage solutions.
In contrast to closed "shelf" storage solutions, Amvolt storage systems use prismatic LFP battery cells (easy to replaceable individually), to which we have a good strategic approach, and the electrical components (BMS, protection, etc.) are handled in the form of industry-standard modular devices.
Amvolt battery storage systems, whether Battery Containers or Battery Packs for indoor usage, are assembled in a modular and tailor-made manner. We use industrial LFP (LiFePO4) prismatic cells of world-renowned brands Winston or Elerix, which are supplied by our parent company GWL a.s.
The cells are characterized by high safety and long service life, they are non-flammable and non-explosive. The usual lifetime of a cell is up to 8 thousand cycles, but even after that, the cells can be used for many more years without any problems. In the event of damage to some of the cells in the storage unit, the other cells can be reassembled and used again or the individual cells can be replaced – so the entire storage unit is not damaged, as is the case with closed battery packs and containers.
That's why for each Amvolt storage unit, we always recommend purchasing spare cells with a capacity of 1–5 % of the total capacity. You can learn more about LFP battery cells in the Technology section.
