2.7.3 LV Direct Parallel Connection WITHOUT Certified Inverter BMS Communication (Open-Loop)
As per the Limited Performance Warranty document, a CAN communication between inverter and battery
is mandatory as per the Models listed in this manual.
Note that for installations WITHOUT certified Inverter BMS Communications, it Is not possible to
benefit of the performance warranty
The 5K3-XP Low Voltage Hub must not be used without Certified Inverter BMS Communication.
The
Low Voltage Hub must not be used without Certified Inverter BMS Communication. The LV HUB starts only with the
Inverter CAN HANDSHAKE message, thin imply the CAN BMS protocol in closed loop.
Performance Warranty is not applicable for non CAN-BMS connected batteries

Note Without CAN communication, it is not always possible to perform a correct calibration of the cells due to the lack of interaction
with the inverter. It is therefore possible that the SoC 100% threshold is not reached.
It is recommended to use the minimum and maximum settings indicated, and to monitor the charging process to ensure that
the battery does not go into protection mode for Low or High Voltage, Temperature or Current.
Some inverter Logic or Battery protocol Logic could not allow the battery to reach the 0% in order to prevent the inverter shut
down * ( DC Powered)
Use conservative settings in order to respect the Limited Warranty Parameters and avoid damages to the battery, such
Overvoltage, Undervoltage, Over or Under Temperatures
