Pylontech ReefMagic PRO 7.5kWh 73V High Voltage LiFePO4 Battery Module
The Pylontech ReefMagic PRO 7.5kWh module is the element of the ReefMagic high voltage storage tower, and one of the highest energy-per-module batteries in our range: the answer when plant room space is tight and consumption is high, in homes and commercial buildings alike.
A tower takes 2 to 10 modules and reaches 75kWh. Putting up to 6 towers in parallel takes the system to 450kWh, so the same battery covers a house, a shop and industrial use. A single module does not work alone: it belongs in the tower with the others.
Pylontech declares a maximum charge and discharge current of 50A, about 3680W at the nominal 73.6V, with two overload steps on discharge: 55A for 15 minutes, about 4050W, and 65A for 15 seconds, about 4780W. The peak therefore sits above the continuous rating, as it should, and fifteen minutes at 55A covers prolonged start-ups with room to spare. The cells are rated for more than 8000 cycles at 25°C and a 15-year design life.
What sets it apart is smart heating for extreme cold: the battery keeps delivering power through harsh winters, where unheated batteries fall back. The enclosure is IP65 with C5-M corrosion protection, so the ReefMagic PRO takes coastal air and severe weather in its stride. Declared depth of discharge is 95%. Installation and commissioning must be carried out by qualified personnel.
