Note: The Wall series - Phoenix's household unit, and the only IP65 battery in their lithium range, so it can go outdoors or in a damp plant room where the rack model cannot. Phoenix print usable energy directly at 4.83 kWh against a 5.37 kWh nameplate, so no derating guesswork. Note the two current figures: 50 A is the recommended continuous charge and discharge, 100 A is the maximum - size sustained loads against the 50 A figure, not the headline. Parallels to 16 units, which Phoenix quote as a 5.37 to 80 kWh range. 53 kg on a wall bracket, so check what you are fixing it to. Phoenix validate this to 6000 cycles and back it with a 5-year warranty, and rate it for 1C charge and discharge - so it will take its full nameplate current continuously rather than needing to be nursed. Smart BMS with cell-level management, protection against short circuit and over charge/discharge. Charge 0°C to +55°C, discharge -20°C to +60°C, storage -20°C to +35°C, humidity 5-95%, up to 2000 m. 16-cell string. Phoenix batteries are made by Century Engineering Industries (Pvt) Limited in Karachi under licence from Kukje Industry Battery Co. Ltd of Korea.
