need to start from battery.
2) NEW: Dual active protection on BMS level.
3) NEW: Automatic address setting when connect in multi-group.
4) NEW: Support wake up by 5~12V signal from RJ45 port.
5) NEW: Support upgrade battery module from upper controller via CAN or
RS485 communication.
6) NEW: Enable 95% depth of discharge, available for the inverter which
completely follow Pylontech latest protocol to operate.
7) The module is non-toxic, non-polluting and environmentally friendly
8) Cathode material is made from LiFePO4 with safety performance and long
cycle life
9) Battery management system (BMS)has protection functions including over-
discharge, over-charge, over-current and high/low temperature
10) The system can automatically manage charge and discharge state and
balance voltage of each cell
11) Flexible configuration, multiple battery modules can be in parallel for
expanding capacity and power
12) Adopted self-cooling mode rapidly reduced system entire noise
13) The module has less self-discharge, up to 6 months without charging it on
