Dyness Stack100 High Voltage Storage System 30.72kWh 6 Modules LiFePO4 with BDU
This is the complete 30.72kWh Dyness Stack100 system: 6 S51100 battery modules of 5.12kWh each, the BDU control unit with its base. One order code brings everything the tower needs, so nothing is pieced together by hand and nothing is left out.
The modules are wired in series, so the tower runs at high voltage: with 6 modules the nominal system voltage is 307.2V. Each module holds 16 LiFePO4 cells rated 100Ah at 51.2V, takes charge and discharge currents up to 100A with a 125A peak for two minutes, and is rated for 95% depth of discharge and more than 8,000 cycles.
Communication runs over CAN/RS485 and the system works with the high voltage hybrid inverters from Deye, Solis, Goodwe, Solplanet, Solinteg, Sunways, Hoymiles, SAJ, ATESS and Sinexcel. Installation and commissioning are work for a qualified electrician.
The complete system costs less than the same components bought one by one. To see each product on its own and get a quotation, visit SolarGear.eu.
