Fortress Envy 12kW with Three eFlex G2 5.4kwH Batteries and Durarack Bundle

The Fortress Power Envy True 12 kW - a whole-home, all-in-one 12kW inverter solution. Paired with the Fortress Power eFlex 5.4 kWh, the eVault MAX 18.5 kWh or LFP-10 MAX batteries, the Envy features a 200A AC passthrough providing up to 12kW (50A @ 240V) or 10.4kW (50A @208V) of whole-home backup power or small commercial. The Envy features a built-in generator input with AC/DC coupling, on- and off-grid capabilities, plus a 3 MPPT output allowing for a maximum of 21 kW PV array. The Envy is equipped with a built-in APsmart Module Level Rapid Shutdown Transmitter and Button, along with Pre-built AC & DC breakers allowing for fast installation and commissioning. Use our online monitoring app to access your system from anywhere. The Fortress Power eFlex is a 5.4 kWh scalable energy storage solution based on safe and energy dense prismatic Lithium Iron Phosphate cells. The digital processor Battery Management System (BMS) includes high amperage contactor disconnects and advanced Closed-Loop inverter communication, as well as individual cell voltage monitoring, temperature monitoring, and cell balancing to maximize reliability and longevity. Canbus, modbus, and wifi communication enable internet-of-things compatibility. The IP65 case ensures direct water spray and dust will not penetrate the battery internals from all directions. The unit can be wall mounted, floor mounted, and server rack mounted for hard-to-reach access in renewable, marine, RV, mobile, telecom, railway applications and more. DuraRack Indoor & Outdoor for Fortress eFlex 5.4 kWh Lithium batteries - Expand your energy storage with the new Fortress Power DuraRack! This iron enclosure stores up to 4 eFlex 5.4kWh batteries. The DuraRack paired with multiple eFlex batteries can build a 48V UPS server rack or provide storage capacity to home solar arrays. The DuraRack includes integrated busbars and a DIN rail heater mount. This enclosure can be free-standing or pad mounted and is safe for indoor and outdoor installations.
