FET is developing and expects to complete in 2024 a storage battery module based on the air-conditioned and sealed container whose patent was released in recent months. This battery module is based on the BMOD10 rack in the version with BMSS-BC and is available in two versions of 15kWh and 30kWh. The nominal voltage is 50Volt. These modules can be applied independently or in Cluster solutions in which the module can be inserted or excluded dynamically without compromising the functionality of the Cluster. This module is completely waterproof and thermal regulated with a temperature range extended from -20°C to +70°C. Particularly suitable for open field applications and in severe environmental conditions on photovoltaic storage systems or on energy back-up systems to support emerging energy communities. The electrical interfaces include a DC bus for discharging and energy recovery, a charging-only PV bus and a control bus typically in CAN or RF standards, placing themselves in the H&S architecture developed by FET.
