The 30kWh storage battery module is a lithium battery housed in a climate-controlled standard container, structured according to F.E.T.'s approved patent. It can operate autonomously or be integrated into a cluster with other modules in the family. The cluster is an electrical and mechanical structure capable of accommodating battery modules, even in hot-swap mode, simplifying both system expandability and maintenance under normal operating conditions when composed of multiple modules.

The battery module can be recharged directly from a dedicated photovoltaic bus and does not require the lithium cell equalization function. The sealed container, protected from dust and atmospheric agents, is equipped with a static heat exchanger that maintains the internal battery temperature within the most convenient operating limits.

The battery modules have a nominal voltage of 50Vdc and a maximum continuous power of up to 20kW with a capacity of 30kWh. It can operate in a temperature range from -20°C to +70°C and with humidity above 80%. The module dimensions are 800x600x800mm (DHL), and it weighs approximately 90kg. The expandable cluster structure can accommodate additional battery modules. With a single module, the base structure and wiring connections are provided.

Currently, the battery module is offered at €11,500, while the cluster structure is available at a one-time cost of €800 per system for B2B supplies. We accept pre-orders for lots of 10 and 100 units and are available for continuous supply contracts. We are also considering offering it to end customers at an indicative price of €10,800, including the cluster structure.
