Title
4.3 HV Lithium-ion Battery
The xStorage Home 3P HV hybrid inverter can be connected to a high voltage lithium-ion storage battery
(HV) to store the energy from the PV panels and to optimize self-consumption.
The xStorage Home 3P hybrid inverter can operate with various high voltage (HV) batteries which have
been specifically tested and approved by Eaton to ensure the safety and optimal operation of the system.
4.3.1 Calibration charge
Based on the state of health of the battery and to get an accurate and reliable state of charge (SoC)
indication, the control module integrated in the battery (BMS) cyclically requests the xStorage Home 3P
hybrid inverter to carry out a calibration and to charge up to 100 %. This allows to make the best use of
the battery, maximize the useful life of the internal cells and to optimize battery performances.
WARNING:
Connect only the battery models approved by Eaton to the xStorage Home 3P hybrid
inverter. Contact your Eaton sales representative to get further details.
The calibration charge is primarily carried out by the energy coming from the solar panels which is
entirely destined for this purpose. If the energy available from the solar panels is not enough then
the remaining part is taken from the grid.
The duration of the calibration charge depends on the energy available from the solar panels and
on the health of the cells of the battery. This process can take a long time (hours and / or days)
especially during the winter when the available solar energy can be very low.
The calibration charge status is shown on the display status bar.
WARNING:
During the calibration charge, normal system functionalities are disabled, and the
battery cannot be used by the system. All system functionalities are automatically restored at the
end of the calibration process.
WARNING:
Calibration charge is required by the battery integrated control module (BMS). The
xStorage Home 3P hybrid inverter cannot in any case disable the command from the battery.
WARNING:
During the calibration charge the EPS mode is disabled. It is automatically restored at
the end of the calibration process.
