Warranty Period
see Limited Warranty terms
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
shutdown * (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
