WARNING:
The maintenance charge is a safety function of the battery to avoid damages. For this reason, the xStorage Home 3P hybrid inverter
can activate grid charging if the available photovoltaic energy is not enough.
WARNING:
During the maintenance 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 maintenance process.
WARNING:
During the maintenance charge the EPS mode is disabled. It is automatically restored at the end of the maintenance process.
WARNING:
Maintenance 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.
The maintenance charge brings the state of charge from the minimum value to a value determined by the BMS based
on the state of health of the cells. The charging current is also determined by the BMS module based on the health and
temperature of the battery itself.
The duration of the maintenance 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) especially during the winter when the available solar energy can be very low.
During the winter period or after long periods of inactivity, the battery may remain at the minimum state of charge for a long time
with the risk of a deep discharge phenomena with consequent risk of structural damage to the internal cells. Therefore, to avoid
damages of the battery, the control module integrated in the battery (BMS) may require the xStorage Home 3P hybrid inverter to
carry out a maintenance charge.
